ZY Plotter 2.0 Y axis friction problem

#1

Hi!

Recently I bought a XY Plotter 2.0 and I’m quite happy, but there is one issue that is preventing me to create perfect drawings. One of the sides of the Y motion (the one that has the X motor in it) seems to have higher friction than the other side (I tried the bars before assembling and they seem to be okay). This is making one side start moving while the other is just stretching its belt. I already tried to tighten this belt but no success.

The result is that round motions loose their round shape to slightly become an egg. Haha

Any suggestion on how to solve that?

Thank you!

prüfe bitte die Einstellungen der Dip Schalter auf der Treiberplatiene. In MDraw sollten alle drei au HI stehen in Benbox nur die ersten beiden.

please check the settings of the dip switches on the driver board. In all three MDraw au HI should be in Benbox only the first two.

I would suggest you check all four belt pulleys and the collars securing their bearings to the idler shafts to make sure the collars aren’t pressing the bearings too tightly, and that the pulleys are directly in line with the securing points on the sliding carriage.

It might also sound counter-intuitive, but have you tried slackening the tension slightly on the belt that is too tight, so that it has the same tension as the other belt? Neither of my belts are especially tight.

@Gundelputz , the switches are all set to High. Thank you!

@Adrian_S , I’ll try making the changes you suggested tonight. Let’s see. :slight_smile:

I have the same problem. The plotter used to work perfectly until few days ago the problem started. Basically the the motor of the y axis so start to move slightly out of its rotating axis. Egg motion or small yawning motion.

First step I switched the motors, but both motors are working fine…

Second I dissembled the holy y shaft and reassemble it in the hope make sure everything is in a straight line… this did not fix the problem…

Next step I want to change the shaft (D4x512mm) and 4mm coupling… the problem is now I can’t find the D4x512mm shaft on the web site… I already wrote an email, but sofar there is now answer.

I have been now 7 days without my plotter… sad story sofar…

Hope for help or ideas.

Cheers
