I've experimented with various versions of the Arduino IDE and Repetier Host on an old Mac laptop. The combo that seems to work the best is Arduino 1.0.6 (with the pins_arduino.c file added) along with Repetier Host 1.2.0. I'm able to compile and upload, and then I can control the motors, heat the machine, and extrude plastic.
But I just can't seem to get the configuration right. It seems like every movement goes much farther than it should. For instance, if I set the _MAX_LENGTH values to 360 and lower the nozzle down to the glass, the Z value will still be about 123 or so. And if I try to jog it over towards the Z column, for instance, by the time I get to Y70, the arm is just about parallel with the column. Also, the farther I move the platform from the center, the higher it goes. At the edges it's raised more than a cm.
It wasn't always this bad. I seem to remember it moving fairly accurate distances and staying pretty level. Here's what I've tried so far:
- Repetier-091-ROSTOCKMAX-master (with inverted Y axis)
- Firmware-master (with modified v2 settings)
Does anybody out there have a Rostock MAX v1 that hasn't been upgraded and is properly configured? If so, please share your settings or give me some idea what to do. Thanks.
