Im working on this stage https://wiki.e3d-online.com/Printer_Commissioning Having issues at the tightening of the axis stage. I'm doing up the y axis now, but at the end it says to test the smooth running of Y, and I noticed it doesn't want to stay in position at the back. Is this normal? I thought some cables might be pushing it back, but it's all free. Something seems to be pushing it back. See towards end of my video here: -- update: cant seem to upload a video, are they restricted here? Space issues probably... I'll try and describe the issue. I move the extruder to the back of the printer, and when I let go, it slides back forward a bit. Like something is stopping it from staying in place at the back. No issues with this at the front. What could be causing this, are the bars not straight? Too close or too far at the back? I have looked carefully for cables or anything, but it seems good. Thoughts welcome. Can provide video too if someone can suggest where to put it.
