Motor Steps/mm configuration
Hello,
I have a Prusa i3 R2 with Motech motors Nema 17 1.8° 4,4kg, Ramps 1.4, Drivers DRV8825, belt GT2 step 2mm, pulley with 20 tooth.
In repetier firmware i used tihs configuration:
and also
#define X_MAX_LENGTH 200
#define Y_MAX_LENGTH 200
#define Z_MAX_LENGTH 210
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
(a friend with the same hardware sent me this configuration and it works properly with his printer).
Using repetier calculator, the numbers should be ok (80) for X and Y.
I launched Repetier host and I clicked on HOME-X button and the extruder went correctly on the left side to the endstop and stopped setting the point X=0.
Then i clicked on the X button to move to the right side with number 50 for 4 times and the extruder reached the center of the X axis instead of the end and the X coordinate is X=200 and it's wrong because it's in the middle instead of the end of te right side.
If I click more than 4 times on X button the extruder doesnt't move on right side (I think because in the configuration I have correctly #define X_MAX_LENGTH 200 and it think to be at X=200 instead of X=100).
Why it happens?
80 steps should be te right number with my hardware.
Thank you,
Roberto
