Yes this type of extrusion is called a v-slot 4080 cbeam. I had it left over from other projects, although it is overkill for this project. On the other hand, I didn’t have any flex issues! I thought it would be interesting to integrate the belt within the frame to provide more usable travel area!

Thanks Pete!! That is very tempting 🤩🤩

Thanks for your comment! I have roughly calculated to come to a maximum of $750USD. This includes everything such as hardware and electronics, however only with plastic 3D printed parts. An additional cost for machined metal parts!

@@NEWTechCreative Thanks! That's a bargain tbh - Well done! looking forward to see updates :)

Thank you! Let me know if you need the yaml setup file?

Great point! I didn’t even consider this. Thank you for bringing to my attention 👍

😆🙏

Thank you! Great to see the new Ortur H20 machines coming out 👍👍

@@NEWTechCreative If you like this machine, we can always send you one for testing.

@@NEWTechCreative Do you have more ideas about laser engraving machines now? I can't wait to communicate with you.

Thanks for your kind offer!

Absolutely! I did have that in mind 🤩

Sure thing!

@NEWTechCreative appreciate it dude! Haha 😂 good video btw

Awesome idea! I never had thought of that. This would be a great way to support belt if it has enough attraction. I might try I out. Thanks for this 👍👍

Dude! Thank you for your comment! Love the your thinking, direction and ideas. I was working on a small program a while back that could easily adapt a rotational axis mainly for drag knife or concrete extrusion machine and this would be perfect for what you’re suggesting. Essentially the program uses the current and future locations to calculate angle of z axis before moving and adds extra gcode as needed. This is a nice rabbit hole to go down for fun 🤩 Thanks for your support and ideas 💡

Thanks for your feedback!

Yep super unprofessional..... the video is way lower in volume than the screaming intro music.

I too am making a large corexy and would like to know what counts as affordable.

@kurtnelle I went and put my parts into PCB way after making that comment, so for printed aluminum like his mine cost about 70 USD according to the auto quote for two carriages which honestly seemed a little steep considering they are basically c channel but if you pick ABS the price tanks to less than 20 USD.

When manufacturing one off parts, no matter the process of can seem expensive, however compared to what it would cost traditionally for a one off item, they are incredibly reasonable! You might be able to get away with 3d printing the parts if you have access to a printer 🤩🤩

@NEWTechCreative yes that is true.

first of all. no the plotters were not much faster. second, our toolheads are much move heavy. plotters also were no corexy machines, they are analog to what we call bed slingers.

This is very true! Nothing like reinventing the wheel 🤩🤩

Yea accelerating a piece of paper isn’t comparable to accelerating a print bed. Also the same applies for a pen vs a tool head

Right?! We need to stop tinkering and making because there are or were commercially available options 40 years ago! It's about the adventure and the results are modular platforms that can be built to do a great number of things. That didn't stop me clicking on your link to see what I could learn from the OG's, though. :)

Checkout on Aliexpress and search for ‘Right Angle Acrylic Bender’ 👍👍

500mm corexy printers have been a thing for years and at least one upcoming model has 600mm.

this is just not true... there are a lot bigger printers than 350x350mm... and rack and pinion? thats super expensive and heavy... not really needed for light weight machines like this

Good point! The only issue with rack and pinion is it adds to the weight of moving axis.. however far more effective with precision 👍👍

@@SaHaRaSquad keyword: at best there's a reason tronxy500 is not popular, it's too slow for its size

@@PorkChopForLifeMC "light weight" have you considered... 3d printing the rack? you can even make it herringbone

Very interesting! I will have to look into this. Thank you 🙏

also, what power did you use for the 3mm clear acrylic?

Thanks for your comment! The distance calibration can vary from machine to machine. It’s best to do the ramp test to check. There were some additional materials that the machine came with, however unsure if they were for measuring focal point. I believe I ran the acrylic at 9mm/sec at 85% power… I’ll have to check actual settings.

@@NEWTechCreative awesome, thanks! the 3mm acrylic in the video looked awesome

There is a switch at top to turn on. If that doesn’t work, it needs to be charged or might even have a battery fault - also check that everything looks plugged in!

Thank you! Whilst fluidnc is built mainly for milling/laser (diode/C02), there have been many folk who have been successful with plasma! Maybe check out the fluidnc wiki and the fluidnc discord for more info 🤩

Yes that is correct! The esp32 only has a small amount of storage. You won’t be able to upload more than one or two small gcode files to the flash storage 👍

​@@NEWTechCreative I have installed the SD card module, but it can't be read even though it matches the schematic, is there anything else that needs to be added or do you think I made a mistake? please give me a solution

@@syarifhidayatullah5858 please send me an email to newtechcreative@gmail.com and provide an image of your setup and yaml file to assist further. I assume you have setup your yaml file correctly. Not that some Sd cards don’t work especially newer higher capacity cards. Best to use older 4gb cards.

@@NEWTechCreative ok thanks😁

Yes absolutely! Just wanted to show possibility of importing for illustrator.

Yes the dxf drawings should be on my thangs profile. If you can’t find, please send me an email to newtechcreative@gmail.com

Great question! If you haven’t had a chance to view this wiki, check it out. wiki.fluidnc.com/en/hardware/3rd-party/MKS_TinyBee This shows gpio.2 for the ‘S’ (signal). There is a pinout IO diagram where to find it there as well. You will need to hookup an external 12v to laser and split your GND to one of your GND pins on tinybee and to your 12v supply. If you are powering your tinybee with 12v, you can wire the board and laser from same power supply, otherwise find a dedicated 12v to power your laser separately. Over voltage will fry your laser module. When you see the example on the wiki, copy and paste it into your own yaml as it provides the hz and speed map already. Here is the section to copy for yaml: Laser: pwm_hz: 5000 # on 3D Touch connector (has pdwn + PWM) output_pin: gpio.2:high:pd s0_with_disable: true tool_num: 1 speed_map: 0=0.000% 1000=100.000% Let me know how you go!

​@@NEWTechCreative Thank You so much! I managed to get the laser to fire and the axis all moving in right direction and homing the way I want! I only tested at 1-6% power and see a difference. I will test it better tommorrow once I get wiring cleaned up and old laser out... The bad news is I had a accident and will be repairing my Lasertree 4-LDS control board... the 12-24v input to the adapter card had reverse +/- and I might have cooked the laser module. I am upgrading at the same time to the Laser tree K30 I couldn't turn down the pre black friday sale on now! I am tiding up wiring and looking to activate the fan via the fan 1/2 outputs on the Tinybee. I have seen the pinout diagram shows this to be IO147 and IO 148. But the example I have seen says - # FAN1 enable_pin: I2SO.16 I have also seen someone say they added a fan using this: #fan user_outputs: digital0_pin: i2so.19 I have tried a few things but can't seem to figure it out. Does this need to be in a specific spot in the config? How would one use the "fan1" output and does it come on all the time or only at a certain point? Thanks again for all your videos and help! It has been one of the best references I have found about tinybee. In fact I learned about it from your fluidnc flash video!! I returned the MKS DLC and got this 6 axis card!

Thanks for your message and sorry to hear about your laser board. Hopefully the new module will work ok. Yes you are on absolutely the right track for the fan output pin. The mks labeling of pins is quite different from the fluidnc pin labeling. Digital outputs work with the m63/4 p0 command. If you type m64 p0 into your commands, this should turn the digital_pin high (on) and typing m65 p0 will turn low (off). The digital_pin:1 will be controlled by m64 p1 and m65 p1 etc. if you use m62 and m63- this will be in sync with motion. Hope this makes sense? You can insert this into your gcode or make a macro to have a quick access button to turn on and off fan when needed. If you need more help with this, feel free to send me an email to newtechcreative@gmail.com

lol

Thanks for your comment! After using the machine for more time I realized that the small ‘blow outs’ were caused by the honey comb bed under the material and if I raised the acrylic material away from bed with some scrap pieces of acrylic, all the small ‘blow outs’ disappeared and had a great finish.

Thanks for your reply! I will consider getting this machine.

Absolutely… ensure you have your extraction hose well away from you and others as leather smells worse then burning hair.

Great question. There are some aspects that can influence clarity in finishes for engraving and yes you can get reasonably clear surface finishes with the correct line interval and multi passes at different directions etc. there is also post processing options to further smooth surfaces. I’ll attempt to have a play for you and show results sometime today.

Great insight 🤩

🎾

@NEWTechCreative please more of those shots from the basement ,thanks 🤣

I agree that this board has some design issues. However, I’m not entirely clear on your point about the copper plane. Most boards will have a copper plane or ground plane, which also assists with heat dissipation. If you are referring to the black section under the ESP module on this board, this is an antenna area.

Must be ground to complete the circuit for inputs 👍

Absolutely! As long as you keep it around the size of an A4 piece of paper 👍

Great question. Yes you can run 2x motors off one driver, however the driver can only output max 5.6A and under power your motors (2.8A each). Best solution is to buy another driver and split step and direction from y axis from the uln2003A chip (yes only one needed per axis output). Alternatively you can purchase a dedicated esp32 CNC board that has additional outputs to control y axis separately and save additional wiring.

@@NEWTechCreative Oh awesome thanks. I was concerned that the output from the ULN2003A chip might then be underpowered as well for the Driver to work properly, kind of like before adding the ULN2003A and just running off of the 3v that the ESP32 puts out? So thought maybe I might need another ULN2003A chip added as well somehow? But you figure that shouldn't be an issue? Thanks for your feedback, I really appreciate it!

No problems. I like your thinking - very logical! The one uln2003A chip will be more than sufficient to run both Y axis drivers.

@@NEWTechCreative Perfect, thanks man!

I would disagree. GRBL is much better suited for this machine due to compatibility with more programs, wider support for beginners and cost effective.

Purchase here: www.rootcnc.com/product/root-controller-rev-3/

@@NEWTechCreative thanks

Yes. You can run gcode and control directly from the root controller - no pc needed. Only need a device to connect and control via the onboard webUI

As I mentioned in first episode, purpose is to explore building a coreXY machine using materials I had and kinematics…. The build is the purpose and no specific use at this stage.

Thanks for your comment. Some limit switches or sensors have a 5v function for the 3pin setup, however if only using basic switches like mine in the video, only need to wire one side to GND and other to Signal.

Great question! I’ll have to test out… haven’t had a chance to play with images as yet! I expect that it would be straightforward to do so.

Oh sorry to hear! Definitely a different experience from me. Can I help at all?

I think you’re spot on!

Thanks for your message! Difficult to say without seeing your yaml file and a video of what’s happening. Feel free to email newtechcreative@gmail.com or jump onto my discord discord.gg/NDe9uPZf to get to the bottom of the issue.

Yes plans are now available! www.patreon.com/Newtechcreative/shop/matilda-cnc-build-files-307737?Link&

Oh awesome Pete! I hadn’t seen this kinematics. Great idea 👍👍 dual head… maybe we shall see 🤩

Not too sure as yet 😂 my main purpose was building a large scale coreXY machine to explore the build process and possibilities of a larger belt driven machine. Purpose yet to come 🤩🤩

@@NEWTechCreative that's amazing! Build the machine, THEN figure out what to do with it. Love it!
