Firmware fix?]]> https://www.soliforum.com/post/116219/#p116219 I have 2 3d printers and every thing works heating, melting, and the plate heats, but as it get's to the point to start printing it goes to the home corner and stops and starts making a loud noise, if I leave it the noise stops and the head tries to go to the start point but doesn't get there it starts to zig zag and just move around a little at which time I stop it. I have tried every thing I know to get it to work but even my other printer is doing the same thing????? Any help ????? Thanks Ron.

Yeah... actually I've found a whole lot of play in it, so better hold off on advice until I just tighten things up big_smile

Does marlin or repetier have this?

Firmware fix?]]> https://www.soliforum.com/post/115288/#p115288 I wondered about this skew for 2 years and finally figured out why squares don't come out square.  When I installed Lawsy's replacement carriages I ended up with a slight skew (not because of inherent problems with the carriages, but something about how I printed them, or stuck the rods in).  That is, my X and Y axes are not 90 degrees to each other!

Is there a firmware fix for this?  Any suggestions other than printing new carriages, getting new rods, and reinstalling?

(there is also a Z-shift in this print, but that's a problem for another day)
