having an issue. with z and x axis wonder if anyone has had this problem or can help me. Trying to get the bugs worked out of my machine. I have a design of stars that should fit on a 9.5 inch wide board. It starts on the left and carves them in but when it gets to the right side my measurements are off. by like a half an inch. Also when the router is done it returns home it doesn't end at the same point. Also on my z axis if I tell it to do the design 3/16 of an inch deep buy the time it gets done its only 1/16 of an inch deep. My surface is parallel to the x axis and everything is level. I have checked all the screws for tightness. Belts are tight and everything. I can't figure it out. Also my x motor is getting hot like 135 degrees. compared to 92 degrees on the y motors and 112 degrees on the z axis. Any help would be great I am getting grustrated. I have run about 12 test pieces and everything keeps coming out different even though I am using the same design. Thanks, Atkinson934
first you need to calibrate HOWTO Calibrate your CNC Machine for MACH3 or GRBL normally if an axis is losing steps is will do so in the easy direction, Z will drop because going up is harder to do. but your's go up. this means your drivers require a delay between the direction change and the next step and the current delay is too short.

The Motor I am using is as follows: Open Builds MT-2303HS280AW-OB 1.8 degree /step 170420 The Drivers are Wantai DQ542MA Dale
You say the X axis motor is getting hot is the carriage binding up ? What machine is it ? OX ? what power supply are you using ?
It is the OX. Yes motor gets hot. No binding that I can tell. Carriage slides with no problem and little force. On my test last night the X motor went from 69 degrees room Temp to 134 degrees when the carving was done. i dropped my power setting on my driver and that lower the temp down to 100 degrees when it was done. but I can tell the carving quality suffered. I am going to bump it up to the next setting. to see what it does heat wise as well. I tracked the temps from start to finish. At start, then 25%, then 50% and finished 100%. Tracked on all 4 motors, it was an interesting test. Dale
