MPCNC or LowRider2?

- An attempt was made to take a look at my MPCNC and compare it to the LowRider2 CNC. Although seemingly different, it is hard to point out which machine is the better one.
Also, try watching the video on 1.5x speed, helps to endure the whole thing

My summary: These are great hobby machines to learn about CNC routers and they are useful for prototyping. They are not good for production i.e. earning money from their output.
If you need larger than 2ft by 2ft (600mm by 600mm approx) then use the lowrider.
I've contemplating making the lowrider one. What keeps it from moving side to side in the X? Seems like something should be squeezing against the sides of the table
The X axis does not move much from side to side - roller skate wheels do a pretty good job keeping the gantry in place, although there is some backlash. The motors will skip steps and belt will strech before the gantry itself moves any considerable amount. I have added a second pair of wheels under the table for extra support, the solution can be seen here - th-cam.com/video/8YQLOGYW_lA/w-d-xo.html
I appreciate your video. You did a good job breaking everything down. How are the aluminum tubes holding up? are there any wear grooves from the bearings? In the US the stainless tubes are harder to source and are more expensive, but I finally found a place that sells them as shower rods for hanging curtains. The electric conduit I used is pretty good, but the surface isn't the smoothest. It is stiff enough and holding up well. This will help me to decide if I will move onto a Lowrider or not. Are you on the forum? Thanks again.
I am not active on the forum, just lurking around there sometimes..
Aluminum tubes do show some wear and denting on the roller bearing contact spot, but until now there has not been a significant increase in backlash. But it can be compensated by tightening the central bearing bolt of the rail assembly
I would recommend the stainless tubes due to similar hardness of the contact surfaces to avoid problems in the future. But aluminum tubing also works
Where did you find the shower rod?
@@nathan1sixteen My tubes were found in my local hardware store - they are rods for hangers, used for custom wardrobes
What depth per pass are you using on the aluminum? When cutting aluminum use shallower depths.
I cut in 0.2mm depth but I believe I have problems with my router speed. Will try to cut aluminum on the LowRider that has the more powerfull spindle, will see how it works
Do you have an opinion about the Marlow? And have you considered if the low rider could be changed to work vertically on a wall? Thanks for the video.
Did you mean the Maslow CNC? I quess with some creativity the MPCNC could be converted to work vertically, but in my opinion the gains would not outweigh the loss in structural stability
Maslow indeed. Sorry for the typo. My problem is garage space.
I this is a great overview. I hadn't seen such a great back-to-back comparison. I'm thinking about starting with a CNC laser or router, but ultimately I'd like to go with a plasma torch.
I'm considering a laser myself. Also, I have ordered parts to make a vinyl cutter for making stickers. I will convert the MPCNC
If you are burning wood and your bits then your feed rate is to high. You need to slow it down in the software. The spindle should handle cutting wood with no problem.
How do you handle the chips? I saw a video on here earlier with some dude doing aluminum (his video is what made me finally decide to do this) and his aluminum chips would have been about 6 inches deep from one job. They were super fine chips but how in the world does one handle that? I see you have an enclosure, which I will do as well, but how do you get those chips out of there or they will build up and bust something before the job finishes?
I have not done that much of aluminum machining. While cutting, I used compressed air to clear out the cut and prevent chip welding - just manually pointed the blower end of compressor to the cutting action. The blown off chips then collected in corners of the enclosure. I am planning on adding constant directed air nozzle and close off the enclosure while cutting aluminum.
Yes, but how do you handle the chips that accumulate in the enclosure? I need to investigate this more because a standard shop vac isn't going to cut it.
Shop vac did the trick for me - just vacuumed the chips straight up after I finish the cutting. I have a dust bag in my Karcher vac and I dispose the bag in garbage bin afterwards
I have decided on a Venturi effect Vacuum because it doesn't matter that the chips are sharp and wet (with a mister) but a shop vac most people go through in under 3 years if they do a lot of metal.
Have you tried using WD40 when cutting aluminium, I've seen around YT quite a few machinists recommend it
Have not tried yet, but I will :) Thank you for suggestion!
Good Day, I'm thinking of building one but really need your advice I wanted to build one with a working area of 4ft x 3ft just to cut MDF you think it'll be possible?
Hey! I think it would be possible :) But 4ft is quite big for the MPCNC, might have some rigidity issues. Have you looked into the new design for the CNC form V1 engineering?
Hi, I'm working out bed size for my LR2. Yours looks a big enough, what size is it please?
Hey! At the moment usable work area is 1400x950mm, usable Z height 150mm. Basically, it was the biggest sheet I could fit in my Volvo
@@KarlisZalitis Brilliant, thanks for your reply. May have to change my car 🙂 I've gone with your design, double layer tubes, spindle etc. Just working out enclosure and table size, mine will be in my garden shed so noise is an issue. Thanks again
Labs video! Jautājums - kur Tu pirki tās caurules (vadulas)?
Paldies :) Caurules pirku tepat Depo - tās var atrast pie iebūvējamo skapju lietām, tās ir tās kuras izmantoju LowRider2 CNC. Alumīnija trubas pirku KSenukai, bet tās ir padārgas un deformējas zem metāla gultņiem. Depo caurules ir labākas
What is the size and work area of the mpcnc?
The cutting area is 400x400mm, usable Z height is about 50mm
Hello, I assembled my lowrider cnc skr 1.2+ TMC 2130+TFT35 V3.0.1 I need the firmware marlin 2 and configuration step by step Please help me to solve this problem
You should look into building the Gatton CNC. It is way more sturdier than either of those you have. Check it out on youtube before you make a decision. You can make it big enough to do a little bigger than a half sheet of plywood. Costs about $1200 to make one using his kit and other readily available hardware. Check it out.
I will check it out :)
1200 versus 100-300 or even less if you have any 3d printer parts around (my case).
For 1200 I'd go with WorkBee CNC.
Although it has voice sync problem, this playlist has the best CNC videos:

Its really long video :D
Can u please write a summary, what are the main advantages of lowrider compared to mpcnc and vice versa. How should I choose between them? Which one do u think is more precise?
.... it realy depends :D I guess, the main advantage of the LowRider over the MPCNC is the cutting bed size, but you sacrifice rigidity. And many more trade-off's and compromises with winners on both sides... I mainly use LowRider, but it has become rather custom build... What are you planing to do with these machines?
👌 Auf meinem Kanal dokumentiere ich gerade in einem Mehrteiler den Bau meiner MPCNC. Wenn Du Interesse hast, schau gern vorbei.
Viele Grüße von Michael 👍
Danke! werde auf jeden Fall besuchen :)
