Hi,
I am testing a classical h-bot gantry with the Repetier-Firmware.
So far, the movement direction and the endstops are working fine. However, the movement distance along the X and Y axis is not correct:
eg. command G1 X200 makes the extruder move only around +170mm in the X-direction. G1 Y200 moves the extruder only around +170mm in the Y-direction.
Settings (double checked in EEPROM):
XAXIS_STEPS_PER_MM 160
YAXIS_STEPS_PER_MM 160
I use GT2 (2mm pitch) pulleys with 20 teeth. This yields 80steps/mm for a stepper with 1.8deg/step in 1/16 microstepping mode. According to comments in the Repetier-Firmware: "For xy gantry use 2*belt moved!", which I understand as using 80*2=160 for the number of steps per mm in the settings.
How do I get the correct distance travelled along the X and Y axis?
I would be thankful to any comments and help!
