That almost looks like a commercial machine! I'd have an idea: A bent piece of plexiglass connected to a spring that gets pushed away by the Y-Axis. The purpose being the protection of toolholders from shavings. Compressed air is sometimes not enough to guarantee clean surfaces.
Fantastic work. I definitely want to know more about this machine, like many people below. Could you also explain more about the atc spindle? Such as what components you need to get for the whole system to work (vfd, pneumatic components, etc). Thank you
This is a fantastic machine!! I would also like to know more about the details of your build as far as the spindle and pneumatics to operate the tool change. It would be great to also talk about your probe and what model it is, and the machine frame and gantry. You said you would create another video explaining more details. I anxiously await that video. Thank you very much. Great build!
Ok ok, I think it's really time to grab that next video! I see so many questions in the comments. The probe is from drewtronics.org but I'm seeing they changed a bit their model and increased their prices. I promise to release another video in the coming weeks!
Thank you, yep I thought about adding a cover. So far I did not have any problem with chips getting stuck inside the tool holder. That's why I've been a bit lazy in designing one. But of course it would be more reliable with a cover.
Wow, this DIY CNC shocks me. Great job. Thank you. Look forward your next video about its details. I am also interested to see more information about how the frame structures was built.
I posted a new video about the build of this machine. Ballscrews are 16mm diameter x 10mm pitch for X and Y, and 5mm pitch for Z. And linear rails are 20mm wide.
nice job on the build, Is it possible for you share and post a video on the electrical pneumatic schematic required for the atc.And what was required for setting up Mach etc. post your post processor code etc
Yes, that's my next video I think, more details on the ATC mechanism and control. Then one about the control software, I'm using LinuxCNC and not Mach.
Make a cover for your tools that automatically uncovers them when it changes tools - it’s bad to get debris on the tool taper or inside the spindle taper
Hey Yann very nice setup sir, I'm extremely interested in knowing what parameters you utilized to get your Drewtronics touch probe to work , as I'd definitely like to set my cnc up to operate similarly like yours as well as the ATC setup, if you don't mind sharing that info
I too would like more details on your DIY CNC. Looks like an 8020 design support structure but can't see much else. Also the tool changer is a must for a machine of this size...which is?
It's based on 40x40mm aluminium extrusion. The gantry is 160x80mm. And both pillars on each side are 80x80mm. And the table is a mix of 80x80mm and 80x40mm. The usable table size is 1400x1000mm. I know I need to realise another video! I just have to find some time and grab my camera to show a bit around the machine and explain a bit more how I built it :)
Great work, you've inspired me to up my game, thanks. Any thought on vacuum extraction and or coolant? You seem to be getting great results without but for aluminium I love the fogbuster system and for dry cutting I'd really want to get rid of the chips. To keep the ATC spacing sensible and still have a vac boot isn't the easiest thing to lay out... Love the retractable probe and the auto align is the icing on the cake 10/10. Cheers Owen S.
Thank you for your comment, glad I could inspire you :) I have an air/mist coolant nozzle, you can see it on some of the video shots. But at that time my main compressor was broken and I did not have enough air pressure for both the air mist and the tool change. For this particular part I did not get any jamming or recutting problem, but it's always better to have at least an air blast. Regarding the mist, I tried with air+alcool. But I did not like the smell that filled the air in my garage. It was hard to fine tune my low quality nozzle to get the proper air+alcool mix. But milling dry on this particular alloy works great. I guess it depends a lot on the aluminium alloy. The vacuum chip evacuation would have to be retractable for tool change, but it's hard to obtain the correct clearance with my tool holder. And I like to see what I'm cutting. So I did not invest effort in designing a good vacuum chip evacuation. And I'm only milling plastics and aluminium. I don't mind manually air blowing my table to clean it. But if I was milling wood I would have definitely designed one.
I'm curious how well this spindle holds up in the long run. I run a pid controlled porter cable. It's great and has fantastic torque down to 6k rpm, but the manual tool changes have me wanting to upgrade. I mill aluminum with it pretty well, it seems like yours does too. Very nice!
TheDbsharp you question is: do you really need fantastic torque at 6k RPM? On aluminium you can run at 20k or 30k RPM using “HSM tool path” and get the same removal rate with less torque requirement. And bonus is that you also have less radial forces and less gantry deformation. Running fast is a win almost everywhere :)
Great machine and the tool changer and the retractable probe its amazing. A question, how do you dapt the programm of the gcode to the tool change secuence, I am building somethig like your machines.
Beautiful machine, may I ask what software you are using? Had the same idea but don’t know how to integrate such a probe and configure my current software (UCCNC) to do something like that.
Very good. Like the vertical retraction of probe. When the parts finished one side and flipped over, you don't need to do any parallellism and straightness alignment works. The probing routine does the adjustments. How can it be achieved and what software you used. Or you make it yourself. Very cool. (Is it from 3d printer bed alignment software. How do you incorporate it into your probing routine?)
I'm using LinuxCNC but this can be achieved with any controller. I programmed a routine in G-Code that does a 6 points generic rectangle probing with some G38.2, some moves, some basic calculations, and a coordinate system change at the end with G10 L2 (X, Y and R). It is 100% pure G-Code. Then I did a "remap" with a custom M code (M601) to call this routine with the stock size as argument. Here is the doc : linuxcnc.org/docs/html/remap/remap.html Then when I need to probe a 200x200 rectangle I call my routine with 200x200 as argument: M601 P200 Q200
Hey Yann! I'm going to order all the aluminum for my CNC router soon when I finished my 1700mm 3D printer. Your video helped me so much with the design of the CNC! Thanks a lot for showing it. I've designed my work area to be 800 x 1400. How large did you make the Z-axis? Seems to be around 20cm , judging from the 80 x 160 profile? :)
The Z travel is 190mm and the height of the gantry over the finished vacuum table is 140mm. The extra Z travel is needed to get enough clearance with long tools. So I can really uses my 140mm even when a 80mm long endmill is mounted.
Very impressive, very much look forward to seeing your plans! What is the filter you're using on the VFDs? Do you findf it effective? I've been looking at getting one for my lathe.
On small weak machine like this one, yes it’s better to have 1 flute, a high speed spindle, and a fast feed rate so that the single flute is feed consistently. The feed is between 0.05 to 0.1mm/teeth/revolution.
I'm using LinuxCNC, and it's pure G-Code, using G38.2 to probe different points, then "G10 L2" to change the working coordinate offsets. I could add more details in my next video.
I probe 2 points on a side (actually 2 points on each side and I average), then I compute the x/y vector between these 2 points and compute the angle with an arctan. Finally a G10 L2 P0 Rx to apply that angle to the coordinate system. Here is some code for LinuxCNC: #1111 = [[#1021+#1031]/2 - [#1051+#1061]/2] ; dx #1112 = [[#1022+#1032]/2 - [#1052+#1062]/2] ; dy #1113 = [ATAN[-#1111]/[#1112]] ; dr #1114 = #[5210+20*#5220] ; current r G10 L2 P0 R[#1113+#1114]
@@YannPomarede Thank you again. Seems to be Linux CNC Specific, I can not find a reference for other conttrollers (like Mach4) to support an angle (R) in G10. Semms to be a great benefit for Linux CNC.
this is great :) how did you program the T1 T2 ... did you create macros or subprograms with the position for each tool slot? I presume there is an M-code for the air line.
I created 3 macros: one to unload the tool, one to load the tool, and one that combine both to do a full tool change. For the move to the right position I use the following: O SUB # = 132.0 ; x position of first tool # = 55.0 ; offset between each tool # = 1406.6 ... G53 G0 Y[#] X[#+#*#] ... O ENDSUB With LinuxCNC # is the number of the selected tool (T1, T2, etc...).
Great job! I was wondering what kind of accuracy and repeatability you are achieving while milling aluminum? Does that change drastically from day to day or week to week? Thanks again for sharing your videos.
Realy like ur remap of probing the alignment of piece . Do u have an ideea to make this with uccnc controller or what is the modular programing codes of this ? Thanks .
I have no experience with UCCNC but reading its "key features" it should be feasible. There is "Parametric programming using internal variables and programming mathematical expressions". You have to create a macro that moves around your workpiece with G00 and G01, that probes with G38.2 (with UCCNC I see in the manual that it's G31) and record the probe points with internal variables. Then at the end some mathematical expressions to compute the center and rotation and apply them with a "G10 L2".
Did you get a 2 pole or 4 pole version of the jianken 2.2kW spindle? Also, would you get 2.5kW or larger size spindle if you could (for aluminum milling)?
It's a 2 pole version (VFD @ 500Hz => 30000 RPM). But I did not know they had a 4 poles with the same specs. Nevertheless I'm very happy with that spindle and I would not change for a more powerful one. My limiting factor is not the spindle torque but the machine rigidity. The max amperage I'm observing (on the VFD screen) is 2.9A (@ 200 Volts => 2.9*sqrt(3)*200 = 1000 Watts). The spindle rating is 6A. I pushed it once to 3.5A milling PVC but I felt it was a bit too much for the machine (noise and vibrations). So in the end I'm only using half its max power... Milling PVC, with a 6mm single flute endmill, I'm confident cutting 10mm DOC * 6mm WOC * 0.15mm/tooth @26000 RPM that's a feed rate of 3900mm/min. It's fast enough for my needs. Milling aluminium I'm using even less power. I think I'm around 2A max. And I go 10mm DOC * 0.5mm WOC (same endmill). I might be limited by my fixturing that vibrates if I go harder. But of course it depends a lot on your tools. I always use single flute 6mm max endmill at high speed (between 20k RPM and 30k RPM). This demands less torque on the spindle and is less stressful for the machine. If you want to mill with multi flute, large diameter tools, at low spindle speed, you won't have enough torque with this spindle. But you will also need a stronger machine.
@@YannPomarede Thanks for the fast reply. I am currently deciding on the best Jianken spindle to get for my needs, which is why I decided to ask you a few questions. Yeah they can customize almost any spindle to your needs (2 pole or 4 pole for most of their spindles). The machine rigidity has been something that I see a lot of people struggling with when they build with aluminum extrusion, so I can see how a 4 pole spindle may be too powerful. Fortunately, I will be using steel for my gantry and epoxy granite for my base, so there should be little issue with too much vibration since the granite will be my dampener. Have you thought about making your base extrusion heavier by using sand? It might be worth a try to see how much the vibrations are minimized since the base would be more stable; less likely to move so much during milling. Anyways thank you again for the response. You have a very nice DIY CNC router. Keep up the great work!
No, I bought it from drewtronics.org, but if you have a lathe, it's not that hard to build. But I built the probe holder (3d printed parts) + the probe retraction mechanism.
@@YannPomarede Thanks for the reply. I see their workshop was destroyed by the Californian wildfires :-( They're setting up in a Texas now. Yeah, I might end up making one myself, although if drewtronics are still selling their probe for $170, once they're back in business, I'm not sure it is worth the effort.
Ha, I didn't know they lost their workshop :-/ The one I bought was even cheaper, without the LED. But I might buy the wireless one for my next machine project. It's not in the same price range, sure, but it's more simple to program and use. It's just a normal tool change.
I bought it 10 months ago at 1365 € shipping included

Man, this looks like an amazing machine! 😍 Want to know everything about it 😋 Would you offer us a full presentation? Meanwhile, would you tell us what control software and electronics you use? Thank you in advance and congratulations for this piece of engineering and crafts👍
Thank you for your comment. It's crazy to see such enthusiasm. At first I posted this video to show the machine to some friends but it has now reached a broader audience! Yep, I'll try to make a video explaining the build more in details. The control software is LinuxCNC and the electronics are: - Mesa 7i96: FPGA board to generate smooth stepper steps + some I/O, ethernet connection to computer - Mesa 7i84: Expansion board with more I/O - Leadshine DM556: Stepper driver with a good DSP, RS232 port for tuning - Leadshine 57HS13: Stepper motors - Leadshine SPS407: 42V / 7A unregulated power supply - 3.5kW VFD for the vacuum pump - 2.2kW / 500Hz VFD for the spindle
I'm interested in assembling a DIY machine but i'm afraid i won't achieve the accuracy and repeatability i'd desire. What kind of an accuracy/repeatability are you achieving with this setup for the contour and depth? Tenths of a milimeter, hundredths for diameters, workpiece contours? How accurate is your probe? With your experience building this machine do you think it's possible to create an affordable DIY cnc that is accurate to an order of +/-5 to 10 microns. Meaning could a diy unit reliabily machine a circular slot with a diameter of say 17,53(+0.03/-0.03)?
I would say that +/- 0.05mm is easy to achieve without effort (with a light finish pass of course). More than that is becoming difficult because I have some backlash in the ballscrews (0.05mm backlash). You can compensate for it of course but still... On a square contour i can reach a repeatability of +/- 0.01mm but it needs a couple of iteration between measurement, offsetting tool path and milling. If your talking microns, it’s still possible DIY but it requires a careful design, and a router style CNC may not be the best choice. The probe is repeatable to +/- 0.02mm
And to answer your last question, I’m not sure I could reliability machine your circular slot at +/- 0.03mm. That would be very close to the limit, but I don’t know on with side of the limit :)
@@YannPomarede Thank you for taking the time to answer. I was playing around with the idea to emulate a Haas VF1/2's basic design as seen in this video: th-cam.com/video/1s7tPqFtBRE/w-d-xo.html going for a simplified steel base plate, saddle and column, table and spindle head to ensure rigidity. Steel itself is not expensive and i have access to CNC machines at work in the shop. Not a router design. I'd only really need a unit that could cut accurately workpieces up to 300 x300x300mm in size so that would simplify the matter immensely. Rail enclosures could probably be 3D printed for a light duty design and sealed with some sillicone and stuff like that. The cutting would likely work out fine with no coolant or with a preassurised air for evacuating the chips from the pocket based on my previous experience. The desire would be to create a miniature full feature medium precision mill (some tool changing) that could have some commercial purpose either in making parts or even marketable. The issue is mostly the rails and the actuators. Did you use first/second hand brand names or chinese knockoffs and what preload (if any) did you get. Besides that, do you have any tips on what to be really careful about if i wanted to design and build such a high precision machine? Another issue would be the cost. How much did your project cost approximately? I know how much i'd like to pay and i'm afraid i wouldn't be able to achieve that without chinese preloaded cheapos.
The exact one in this video is reference A1L6_17 on this website: www.htk.fr And I also bought some other tools (and also tool holders) here: www.aliexpress.com/store/1159132
nice, i also wanted to build myself a cnc, but it would have been way to expensive (because of 5 axis and every axis would have glass scales with servos and rotary encoders as well as a custom ATC spindle with chain tool magazine laser tool probe and custom 3d touch probe)
It does not need to be a fancy one, I just bought components separately: a mini ITX motherboard with CPU included (Celeron J3355), 4GB RAM, a SSD and ITX case. The high frequency step generation is done with an external FPGA card (Mesa 7i96). So I did not need ultra low real time latency as when you're using the parallel port to directly drive the steppers. Here the communication between the PC and Mesa card runs at only 1000 Hz over the ethernet port.
@@YannPomarede understood. I'm planning to built a cnc like this, so I'd have some questions in my mind. 😅 Your machine works really good and seems to be big enough for my future plans. Have you got a blog or a facebook page to have more info?
It seems to be kind of bs. Vacum fixture? Ok. Sort of probe. Maybe. But when he turned piece over and probe the edges WITHOUT clocking it? This will never gonna work out.
If you look closely you will see that a probe 6 points around my workpiece and I adjust X, Y and the rotation of the coordinate system. I don’t need to square the “vice” or the workpiece ;-)
Amazing! Wow! I have the JGL100 2.2 kW Spindle version, but still not installed! What breakout board do you use? Do you use Mach3/Mach4? How did you program the tool change and the auto probe?

What vacuum pump do you use for this table?
Are you gonna be selling parts to build a c n c
How have you done the auto probing and re alignment? Whould be great to see that!
I'm using LinuxCNC, and it's pure G-Code, using G38.2 to probe different points, then "G10 L2" to change the working coordinate offsets. I could add more details in my next video.
@@YannPomarede thank you for the Tipp. For coordinates of work Zero this is understandable, but how do you compensate the angle of work piece?
I probe 2 points on a side (actually 2 points on each side and I average), then I compute the x/y vector between these 2 points and compute the angle with an arctan.
Finally a G10 L2 P0 Rx to apply that angle to the coordinate system.
Here is some code for LinuxCNC:
#1111 = [[#1021+#1031]/2 - [#1051+#1061]/2] ; dx
#1112 = [[#1022+#1032]/2 - [#1052+#1062]/2] ; dy
#1113 = [ATAN[-#1111]/[#1112]] ; dr
#1114 = #[5210+20*#5220] ; current r
G10 L2 P0 R[#1113+#1114]
@@YannPomarede Thank you again. Seems to be Linux CNC Specific, I can not find a reference for other conttrollers (like Mach4) to support an angle (R) in G10. Semms to be a great benefit for Linux CNC.
@@ravenvg Mach3 and UCCNC support G10
please can you tell me which Spindle you use
I already answered this question just below :)
this is great :) how did you program the T1 T2 ... did you create macros or subprograms with the position for each tool slot? I presume there is an M-code for the air line.
I created 3 macros: one to unload the tool, one to load the tool, and one that combine both to do a full tool change.
For the move to the right position I use the following:
O SUB
# = 132.0 ; x position of first tool
# = 55.0 ; offset between each tool
# = 1406.6
...
G53 G0 Y[#] X[#+#*#]
...
O ENDSUB
With LinuxCNC # is the number of the selected tool (T1, T2, etc...).
Fine job, you got us drooling. Lol
Great job! I was wondering what kind of accuracy and repeatability you are achieving while milling aluminum? Does that change drastically from day to day or week to week? Thanks again for sharing your videos.
super, but teach me I also want to implement my new cnc with a tool change
Hi, what is your controller
dat is dope AF
This is not DIY level, this is way more advanced and capable then high level cnc routers from china
Amazing job, you can help me with autoprobe in LinuxCNC ?
How does the atc work making a cnc on my and would like to know
Realy like ur remap of probing the alignment of piece . Do u have an ideea to make this with uccnc controller or what is the modular programing codes of this ?
Thanks .
I have no experience with UCCNC but reading its "key features" it should be feasible. There is "Parametric programming using internal variables and programming mathematical expressions". You have to create a macro that moves around your workpiece with G00 and G01, that probes with G38.2 (with UCCNC I see in the manual that it's G31) and record the probe points with internal variables. Then at the end some mathematical expressions to compute the center and rotation and apply them with a "G10 L2".
Do u use a solenoid for probe moving up and down ?
No, it's an air cylinder, with a solenoid valve to actuate the air cylinder of course.
Did you get a 2 pole or 4 pole version of the jianken 2.2kW spindle? Also, would you get 2.5kW or larger size spindle if you could (for aluminum milling)?
It's a 2 pole version (VFD @ 500Hz => 30000 RPM). But I did not know they had a 4 poles with the same specs. Nevertheless I'm very happy with that spindle and I would not change for a more powerful one. My limiting factor is not the spindle torque but the machine rigidity. The max amperage I'm observing (on the VFD screen) is 2.9A (@ 200 Volts => 2.9*sqrt(3)*200 = 1000 Watts). The spindle rating is 6A. I pushed it once to 3.5A milling PVC but I felt it was a bit too much for the machine (noise and vibrations). So in the end I'm only using half its max power...
Milling PVC, with a 6mm single flute endmill, I'm confident cutting 10mm DOC * 6mm WOC * 0.15mm/tooth @26000 RPM that's a feed rate of 3900mm/min. It's fast enough for my needs.
Milling aluminium I'm using even less power. I think I'm around 2A max. And I go 10mm DOC * 0.5mm WOC (same endmill). I might be limited by my fixturing that vibrates if I go harder.
But of course it depends a lot on your tools. I always use single flute 6mm max endmill at high speed (between 20k RPM and 30k RPM). This demands less torque on the spindle and is less stressful for the machine. If you want to mill with multi flute, large diameter tools, at low spindle speed, you won't have enough torque with this spindle. But you will also need a stronger machine.
@@YannPomarede Thanks for the fast reply. I am currently deciding on the best Jianken spindle to get for my needs, which is why I decided to ask you a few questions. Yeah they can customize almost any spindle to your needs (2 pole or 4 pole for most of their spindles). The machine rigidity has been something that I see a lot of people struggling with when they build with aluminum extrusion, so I can see how a 4 pole spindle may be too powerful. Fortunately, I will be using steel for my gantry and epoxy granite for my base, so there should be little issue with too much vibration since the granite will be my dampener.
Have you thought about making your base extrusion heavier by using sand? It might be worth a try to see how much the vibrations are minimized since the base would be more stable; less likely to move so much during milling.
Anyways thank you again for the response. You have a very nice DIY CNC router. Keep up the great work!
Nice machine. Did you build the probe too?
No, I bought it from drewtronics.org, but if you have a lathe, it's not that hard to build. But I built the probe holder (3d printed parts) + the probe retraction mechanism.
@@YannPomarede Thanks for the reply. I see their workshop was destroyed by the Californian wildfires :-( They're setting up in a Texas now. Yeah, I might end up making one myself, although if drewtronics are still selling their probe for $170, once they're back in business, I'm not sure it is worth the effort.
Ha, I didn't know they lost their workshop :-/ The one I bought was even cheaper, without the LED. But I might buy the wireless one for my next machine project. It's not in the same price range, sure, but it's more simple to program and use. It's just a normal tool change.
Why don't you use drills to drill holes?
The cutting forces are much higher with drills. And this machine would not be rigid enough to drill into aluminium.
Really nice Video.. Nice built!
Can you please tell me which kind of Spindle you use?
Thank you really much!
Thank you. The spindle reference is JGL-80/2.2R30-20 from www.jian-ken.com. 30000 RPM / ceramic bearing / water-cooled / ATC ISO20 / 2.2kW / 12kg
Yann Pomarede It looks a great spindle, can you tell the price of one of those?
I bought it 10 months ago at 1365 € shipping included
Man, this looks like an amazing machine! 😍 Want to know everything about it 😋
Would you offer us a full presentation?
Meanwhile, would you tell us what control software and electronics you use?
Thank you in advance and congratulations for this piece of engineering and crafts👍
Thank you for your comment. It's crazy to see such enthusiasm. At first I posted this video to show the machine to some friends but it has now reached a broader audience!
Yep, I'll try to make a video explaining the build more in details.
The control software is LinuxCNC and the electronics are:
- Mesa 7i96: FPGA board to generate smooth stepper steps + some I/O, ethernet connection to computer
- Mesa 7i84: Expansion board with more I/O
- Leadshine DM556: Stepper driver with a good DSP, RS232 port for tuning
- Leadshine 57HS13: Stepper motors
- Leadshine SPS407: 42V / 7A unregulated power supply
- 3.5kW VFD for the vacuum pump
- 2.2kW / 500Hz VFD for the spindle
Where did you get your probe from?
I'm interested in assembling a DIY machine but i'm afraid i won't achieve the accuracy and repeatability i'd desire.
What kind of an accuracy/repeatability are you achieving with this setup for the contour and depth?
Tenths of a milimeter, hundredths for diameters, workpiece contours?
How accurate is your probe?
With your experience building this machine do you think it's possible to create an affordable DIY cnc that is accurate to an order of +/-5 to 10 microns.
Meaning could a diy unit reliabily machine a circular slot with a diameter of say 17,53(+0.03/-0.03)?
I would say that +/- 0.05mm is easy to achieve without effort (with a light finish pass of course). More than that is becoming difficult because I have some backlash in the ballscrews (0.05mm backlash). You can compensate for it of course but still...
On a square contour i can reach a repeatability of +/- 0.01mm but it needs a couple of iteration between measurement, offsetting tool path and milling.
If your talking microns, it’s still possible DIY but it requires a careful design, and a router style CNC may not be the best choice.
The probe is repeatable to +/- 0.02mm
And to answer your last question, I’m not sure I could reliability machine your circular slot at +/- 0.03mm. That would be very close to the limit, but I don’t know on with side of the limit :)
@@YannPomarede Thank you for taking the time to answer.
I was playing around with the idea to emulate a Haas VF1/2's basic design as seen in this video: th-cam.com/video/1s7tPqFtBRE/w-d-xo.html going for a simplified steel base plate, saddle and column, table and spindle head to ensure rigidity. Steel itself is not expensive and i have access to CNC machines at work in the shop. Not a router design. I'd only really need a unit that could cut accurately workpieces up to 300 x300x300mm in size so that would simplify the matter immensely. Rail enclosures could probably be 3D printed for a light duty design and sealed with some sillicone and stuff like that. The cutting would likely work out fine with no coolant or with a preassurised air for evacuating the chips from the pocket based on my previous experience.
The desire would be to create a miniature full feature medium precision mill (some tool changing) that could have some commercial purpose either in making parts or even marketable.
The issue is mostly the rails and the actuators. Did you use first/second hand brand names or chinese knockoffs and what preload (if any) did you get. Besides that, do you have any tips on what to be really careful about if i wanted to design and build such a high precision machine?
Another issue would be the cost. How much did your project cost approximately? I know how much i'd like to pay and i'm afraid i wouldn't be able to achieve that without chinese preloaded cheapos.
Где можно купить?
Je suis très intéressé par ta fabrication et j'aimerais que nous en parlions si possible

Hello, are you interested on sale the macros?
Perfect..
Can you tell me where i can buy 6mm 1 flute cutter ?
The exact one in this video is reference A1L6_17 on this website: www.htk.fr
And I also bought some other tools (and also tool holders) here: www.aliexpress.com/store/1159132
Is it Linux cnc ?
como comprar
do you sell cnc router?
nice, i also wanted to build myself a cnc, but it would have been way to expensive (because of 5 axis and every axis would have glass scales with servos and rotary encoders as well as a custom ATC spindle with chain tool magazine laser tool probe and custom 3d touch probe)
ราคาเท่าไหร่
Amazing project. How much does it cost in material? there's a reference to replicate this machine? Congrats for your work!!
Everything included (with computer, vacuum pump, compressor, accessories, vacuum table, etc...) I think it's around 8000 €.
@@YannPomarede thanks for the answer. Which kind of pc did you use?
It does not need to be a fancy one, I just bought components separately: a mini ITX motherboard with CPU included (Celeron J3355), 4GB RAM, a SSD and ITX case. The high frequency step generation is done with an external FPGA card (Mesa 7i96). So I did not need ultra low real time latency as when you're using the parallel port to directly drive the steppers. Here the communication between the PC and Mesa card runs at only 1000 Hz over the ethernet port.
@@YannPomarede understood. I'm planning to built a cnc like this, so I'd have some questions in my mind. 😅 Your machine works really good and seems to be big enough for my future plans. Have you got a blog or a facebook page to have more info?
nice!
It seems to be kind of bs. Vacum fixture? Ok. Sort of probe. Maybe. But when he turned piece over and probe the edges WITHOUT clocking it? This will never gonna work out.
I don’t understand what you mean by “clocking it”? Could you explain?
th-cam.com/video/cn05fX55pqc/w-d-xo.html
If you look closely you will see that a probe 6 points around my workpiece and I adjust X, Y and the rotation of the coordinate system. I don’t need to square the “vice” or the workpiece ;-)
Amazing! Wow! I have the JGL100 2.2 kW Spindle version, but still not installed! What breakout board do you use? Do you use Mach3/Mach4? How did you program the tool change and the auto probe? If you want to see more of my actual work, please see her: facebook.com/NTG.Innovations/
