Hi! I'm building a adapted OX cnc. Everything is wired and jogging around works just fine. I'm using a 24V power supply with a CNC xpro V3 board, nema 23 motors, mechanical limit switches and universal G code sender. I'm experiencing following problems: 1. Jogging on 1 axis is working fine. However, when I give the command to run on more than 1 axis the board or software sometimes freezes, all axes come to a sudden stop. On the board, the motor LED's are lid up, closing and reopen the COM port doesn't help. It doesn't reply on any command... I have to unplug the USB and restart the board. 2. I often get an ALARM message in UGS, first I thought it was a false hard limit trigger. I used a oscilloscoop to check the noise, I is well bellow 500mV. To be sure is changed $10 to value 19, so I can see the state of the limit switches. The response is always limit 000 except when I trigger it So why does GRBL goes into alarm? I ran the software on a Mac, now I'm testing it on a Windows but the same errors occur. I hope someone can help me because I'm out of solutions... Anyone has experience with upgrading CNC xpro V3 to grbl 1.1? Does it works fine? And what about Candle instead of UGS? Thanks in advance! Hope to find some solutions here so I can go carve some things!
