Belting set up

Nope. You only need one side for each as “adjusters”.

Have a quick questions with the belts. Like everyone else, I’m pretty much guessing on the tension on the belts. I’ve found that my x carriage still moves ok once I have the belt on…

However, my gantry will not move at all (the whole frame moves before the gantry rolls along the Y-axises). Are my belts too tight? Or is this normal and they will move fine once the motors are powered and moving the gantry from both sides in unison?

Sounds like the Y stepper motors didn’t get the cross over in the wiring that they were supposed to get @NathanGredler

Check the instructions for how all of the wiring is done on the Y axis stepper motors and double check that against your wiring.

Specifically where it says this:

When you get the end through the same hole on the left Y-Plate strip it as before. Now you’ll twist these wires with the left Y-Motor wires. Twist them as follows: red to white, blue to red, green to green, and black to black. Insert them into the terminal block one pair at a time. When you’re done your left Y-Plate should look like this:

At this part of the instructions:

Edit: you’ll also want to check that your V-Wheel eccentric nuts are at their loosest until you get to the end where you “tune” it all and tighten them.

Sorry @sketch42, should have specified - I’m still assembling and have not done any wiring yet. This is me trying to move it free hand by pushing on the gantry. Just trying to figure out if this is normal before I move onto the next step in assembly. Thanks!

Ah, no… It should move freely. Check that the eccentric nuts are at their most “open” position.

Yeah, that sounds like your v-wheels are too tight, not the belting.

@NathanGredler, they should move like this:

@sketch42, @PeterJames… Thanks for the input… will check the v-wheels when I get home. It would glide perfectly before the belt though!

Hmmm… If it glides perfectly before the belts then ther may be wires touching on the Y-stepper motors… Make sure that the wires aren’t touching anything or each other because they could turn into generators that way, and cause quite the resistance if feeding each other.

@sketch42 – First I made sure the V-wheels were loose. When that wasn’t the problem I disconnected both belts from the dynamic side. Taking a closer look at everything, one of the motor shafts seems to be locked up - or close to it. It was very hard to rotate. I made sure the wires were separated and not touching, and VIOLA. You were right, maybe I’ll just go ahead and hook those up to the terminal block and get it out of the way. Thanks!

Awesome! Glad you got it sorted.

Yeah, I did the same with mine… I skipped ahead and did the wiring to the terminals and then came back and continued in the instructions.

If you’d like to see what I did during my setup, I posted about it here:

Already got them and machine up and running great. Thanks.

Happy carving.


I cut 3 equal lengths (I have the 1000mm) and ran the x-axis belt through both tensioners. I have what feels like a lot left over. I measured the length of belt, and it’s about 4’5". Am I just to snip off several inches of excess?

After you have your belts routed and tightened, it will be easy to clip off any excess.

Please, I need clear instruction on this. How exactly am i to cut the belt for 1000mm x-carve. I got new 1000mm x-carve i am asseblying at the moment.

The instructions say 7 feet for the X and repeat twice for the Y axis. I simply used scissors to cut my belting to size.

Yep scissors or wire cutters should do the trick and the measurements for each size machine should be clearly labeled in the instructions.

Edit: just double checked and the instructions say to cut the belting into three equal lengths.
