Printer out of control

Moved your thread from the R1 section to the R2 section... might get better answers here

As one who first deal with Robo via kickstarter in 2013 ... I feel your pain

 

As a wild guess (I do not have an R2 -- I do have a C2 and too many R1's)

I would check that the gantry is square. They cover that in their docs : https://help.robo3d.com/hc/en-us/articles/115001792512-Gantry-alignment

and perhaps lubricate the bearings.

The gantry being even a little out of square will cause you grief. It is easy to fix though (I managed to fix my C2 gantry without even having the docs when it first arrived).

 

If you run it for a long time un-lubricated or out of square the bearings will score the smooth rods and that will then make the bearings wear out sooner. So... check this.

On my C2 shipping had managed to knock one of the flanges free from the frame where the rods mount into the plastic frame of the top of the printer. So it was just "floating" and would move around as the print head moved around... that was clearly not good. I managed to get it back into place and then used epoxy to make sure it could not move again.

I own a R2 printer. Since the thread was posted to the wrong forum, how about giving us a chance to assist you with troubleshooting.

@mark tomlinson is correct about the mechanics of the gantry. It would be prudent to check the gantry for mechanical issues.

What type of filament are you using? What is the printing temperature? Which software are you using to do the slicing with? How are you getting the Gcode of the sliced model into the R2 printer?

Also, please read the R2 FAQ.
