I just finished my first MPCNC build and am having trouble with testing it via manual control in Repetier-Host. When I plug my board into the wall and my computer, I have no trouble connecting. However, when I click a manual control option, nothing happens. My baud rate is set to 250000 and I have the latest firmware flashed (I think.) I don’t see any errors in the log, but occasionally commands appear to ‘stack up’ and I will have several commands waiting.
I did not buy anything apart from my wiring harness from here. I printed my parts myself and ordered electronics from Amazon and other sources.
P.S. I’m a complete CNC newbie, so please fully explain any suggestions.
Maybe not. If the 12V was plugged into a dead outlet, then the Arduino and LCD were getting power from the computer, but the motors weren’t. If the outlet wasn’t dead, but it somehow couldn’t handle the 0.5A the power supply uses, then… Yeah, worrisome.
