Problems with X-Axis belts


#1

Hi,

I’m having some problems with the x-axis drivetrain (in other words the gantry). When moving the gantry, the belts become stuck underneath the V-wheels in the direction of travel. Please see the pictures below.

I have made sure that my x-axis tracks are straight - I have even removed the second track to only use one… I have checked that the gantry is square. I tried changing the orientation of the pulley to ensure that the belt runs vertically.

What is strange is that the y-axis movement of the z-axis assembly works perfectly.

Any ideas will be greatly appreciated.

Just my off-the-top-of-my-head thoughts:
1). Is it possible that the belt is twisted one revolution (or more) inside the vertical gantry beam?
2). Could the belt be tensioned too much? (too tight)

Olaf,

Are you able to shoot a video and upload it to the Forum so that we can see and hear what is going on with your Farmbot?

Hi Intelbotfarmer, Marc,

Thanks for the quick replies!

I loosened the tension of the belts and that seemed to fix the problem. I’ll take a video of the bot when I’ve hooked up all the electronics and post it for some more input.

Really appreciate the help!

Cheers
