I'm running the latest version of Marlin on an Arduino Mega with a RAMPS 1.4 controller. The printer itself is home-brew.
I'm still in the early stages of learning how to use this equipment, although the frame and steppers were from a CNC mill that I later converted to a laser cutter, so I'm very familiar with G-code. I've put larger steppers on the X and Y axes, they are from Stepperonline, 17HS19-2004S1. They behave well in all the manual tests I've done (sending G1 codes through Pronterface) and have printed several small "calibration" objects flawlessly.
Now I'm trying to print a case for the LCD control unit, and I'm seeing the Y axis shift to the right bu about .5 mm intermittently when the Z axis increments. I've tried different current settings on the A4988 thinking that the Y stepper wasn't getting enough current when the X and Z axes were both moving at the same time, but it hasn't helped, and I can't duplicate the problem manually with G-codes. I've also tried a couple of different designs, but they all exhibit the same problem. The first layer prints OK, then the perimeter of the case is printed at layer 2, but the Y axis is shifted slightly to the right. If I let the print continue, it will print several layers at the new Y-offset, then shift th the right again.
Any ideas, please?
