Hi. Did you have any problems of syncing those y-axis belts/motors together? I'm considering making belt-driven CNC but with only one motor for every axis. (with axle under the table) I'm little worried about that if you make the y axis with two motors, can you really sync them together properly...

I just found this comment. Sorry for the delay. I have had zero issues with the two motors being out of sync. quite literally the check of a box in mach3. Have you started?

What is the width of your belt it looks 30mm? Also have you machined and aluminum and how did that work for you? Also Since you have had this machine for a while how has the design been so far? Belts reliable? anything you would have changed? Did you change the drive type?

Servus! Einen Kilo auf einen ein Meter langen Arm gehängt gibt 9,81Nm ("die 9,81N wirken auf den einen Meter"). Das Muss man sich erst mal geben: Halt mal 20kg auf ein Meter Entfernung - Oder 200kg bei 10cm langem Ärmchen oder 1000kg bei einem Pully-Radius von 2cm ... ;-) And here for the English folks: Hang one kg in one meter distance to the center and you have 9,81N x 1 m = 9,81Nm - it´s as easy as that ;-). My steppers are nema 35 and about 15cm x 10cm in size, they have 9Nm and it is idiotic and COMPLETE OVERKILL!!! I only bought it because of very bad advice.

Hi Nice to talk to you You did a very nice cnc table and I'm interesting to ask you a question about the linear bearing open end ? Is this type of bearing not accurate or make a backlash during cutting? I'm going to build my table but I'm confused between open end bearing and profile guide rail. Do you think If I make twice 25 mm round bar with 4 open end bearing in each Y axis side ,,gonna fine backlash

Hello @@CarlosManitasV I ended up using a 15mm wide timing belt with steel core, from Amazon. It worked out well for me I added a 10;1 gearbox also from Amazon. I seen alot of talk about being inaccurate because of backlash/slop in the plantary gearbox, but it has good repeatability for my application (it's under 1/32"). The gearbox is on a nema 23 and it is strong. If you are using a nema34 I would probably go with a 20mm wide belt and it might not even need gearbox. Let me know if you have any questions and how it works out for you.

But first I would like to know go to solve those issues in belt driven cnc router's. Because here where I live, most of the cnc routers are made with timming belts and there is a lot of the same issue with them. So let's see if I can come up with a good solution for it. Thanks man!!
