I have a ShapeOko v1.4 with a grblShield v4. When I start carving, the distance moved is off.
For Z (up / down), but the distance is correct.
For X (left / right) and Y (forward / back), each inch moved in the program translates to 5.7 inches on the ShapeOko.
On the grblShield’s original setup, Z has a jumper on the left two pins, and X and Y don’t have jumpers. When I remove the Z jumper, one inch translates to .25 inches on the ShapeOko, so it seems like the left two pins translate to a X4 setting (not X2 as indicated in the following image: https://camo.githubusercontent.com/3a051e30398faa3e25d8ca0c3b321cdc217845d9/687474703a2f2f6661726d392e737461746963666c69636b722e636f6d2f383337372f383530333639383934355f643833623332373734652e6a70676).
When I put the jumper on the left two pins for Y, 1 inch translates to 22.5 inches (not the X4 as exemplified by the tested Z settings. I’m going to try other jumper settings, but since putting the jumper in the same position for Y as Z didn’t produce the same results, I’m doubtful other positions will be better.
I’m not entirely sure how to proceed. Any advice would be sincerely appreciated.
Thanks,
Jason
