X-axis rod forcing outwards, damaging the machine

[veedee 4]

Hi All,

I've got two new UMO+ machines and assembled them last week. When I try to make a print, it looks like there is slack in the belts, because circles have flat sides on them. But after tightening the belts (which were already tight enough) I found out that the problem lies somewhere else.

One of the X-axis rods (the one on the front) is forcing itself out of the machine when it is rotating. Because of this pushing force, one of the endcaps that keep the rods in place is grinding away. Apparently it also creates so much friction that the print quality is greatly influenced by this effect.

I added a steel nail through the center of the endcap to try to lower the friction, but the nail has just completely eroded after a few prints. There is a severe problem here.

Has someone also experienced this effect and/or has a possible solution?

Did you calibrate the x and y axis to be perpendicular?

Yes I did.
