My machine, a 6090 using a DSP controller, has a fairly significant drift problem, but only in the Y axis.
I've tried just about every fix I know of... the J1 jumper fix, greasing the drive screw, resetting the microsteps to max... etc,, etc...
And the only thing I've found that actually does work is to simply manually stop and rehome the machine to Machine Home at the default bottom left of the machine once every hour or so, that makes the step count start over and corrects the problem for another hour or so...
If I just let the machine run through the whole program with no hourly rehoming cycle it will have a Y drift towards the negative...
So what I want to do is to insert a Machine Homing cycle into the Gcode every few thousand lines so I don't have to babysit this machine all night while it's working...
Gcode G27, G28, G28.1, G28.2, G30, G53... all simply send it to the Origin Home, not the Machine Home...
I need it to go to the Machine Home so that the step count starts over... not the Origin...
Does anybody have a simple code snippet that I'm missing, that I can insert and that will allow me to get some sleep???
Thanks and I appreciate all input
