X and Y axis slipping when 3d printing
So I can see that my X and Y axis has slipped mid-3d print. I've seen other threads about this and have tried all of the fixes i've found including
1) Lubricating the machine
2) Replaced the stepper driver boards with DRV8825's
3) Set the acceleration speeds to 80mm/s for X and Y (down from the defaults of 100)
4) Updated to the latest Boxzy interface (v1.6.3)
While doing all of this has reduced the slippage occurances and amounts, I'm still unable to complete 3d prints with a smooth line along the Z axis.
I have very carefully configured my slicer settings such that the last print was *almost* perfect except for a single slight offset (maybe 0.2mm - 0.5mm) on the Y axis mid-way through. The rest of the print then continued at that new Y position.
Has the Boxzy team worked out what is causing this issue yet? I've seen lots of guesses in the unofficial forums as well as on here but nothing where they have officially acknowledged the cause of the problem and suggested a fix. It feels like chaging the driver boards and the accelleration speeds is just masking an underlying problem that needs to be found and fixed.
I haven't been brave enough to try the laser or milling attachments until I don't get any axis slippage (I hate to think what that'll do with a router embedded in material.
Is this a good question?
