Hi cmcgrath5035,
Thanks for the quick and useful responses! Sorry I didn’t come back earlier.
I did encounter erratic operation. One of the Y-axis (the one with the broken cap) didn’t run at quite the same moment as the other Y-axis motor. In fact, it looked like it did one or two steps backwards first, before running in the right direction. That caused the X-axis to run a bit crooked everytime I gave a command for the Y-axis.
I went to the local electronics store and bought a leaded cap with similar capacitance and after some fiddling I managed to solder it onto the board (I soldered the cap to some wires first and soldered the wires to the board after that).
Anyway, the ShapeOko runs smoothly again!! Very Happy 🙂
Thanks again!
