I got my lite kit from Edward. Very happy overall with it. Got one issue I cannot seem to correct enough.
Is anyone else having issues with excessive looseness in the "Y" arm as it moves right or left across the X axis? I just printed a second lower attach plate thinking that there was an error when it was printed. The second plate has the same amount of looseness, so it is not the problem. There is enough play when I am moving along the "X" axis it lags in either X direction sometimes??? Of course with the lag the cut gets trashed/skewed a bit!! I have lubed the bearing on the wheel of the Y arm and it moves freely.
I have tried several different spacers as well (even metal ones) to attempt to stiffen it. It may be an issue with the size of the bearing wheels or something is what I am thinking?? My X axis belt is tight enough, but not overly tight!! I was thinking of slotting the holes on the lower mount plate and tighten the wheels up to the 2040 extrusion as tight as I can get them. I am also guessing there may be a slight difference in extrusions, like my 2040 may be slightly smaller?? The 2020 extrusion where the cutter mounts is solid (no slop / looseness at all). Got both extrusions from the same place.
Any ideas from anyone that may correct this would be appreciated.
