I have started having an issue tonight where my tube stops firing in the middle of my job. I can hold the test button down and it fires as it cuts, but the board (X5) itself isn’t sending the signal? The LCD says 100% (I’m using a pot), but there isn’t anything happening. I’ve upgraded LaserWeb, and I’m using the CNC firmware. The job I’m running starts out vector engraving at 25mm/s, and roughly 4mA. When it gets to the cut I have it set at 10mm/s and 9mA. It’s during the cut that the tube stops firing. I don’t think it’s the water being too warm, as I just tried again after the machine was off for 6 or so hours. I’ve double checked my connections (I’m using a K40 with a LO power supply), and everything seems snug and connected. The tube doesn’t have any cracks or bubbles, and the water seems to be flowing properly. Any thoughts?
Edit: Other strange behavior I’ve noticed yesterday and today. For some reason right after running a job LW decided that it wanted to home to 0,0, instead of 250,0 as it should. I don’t know if that’s related, but I thought I’d throw it in. The problem corrected itself after rebooting my computer a couple of times.
This is puzzling. On a whim I decided to run a cut job and tell LW 80% power instead of 100%. It now runs as it should. I noticed on the 100% job I tried right before that the laser would shoot on and off usually around corners, but the ammeter showed a power level of only 2ish mA.
It stopped firing right when the power hits 100%. I have since rebooted (three times, actually), and as of last night it decided to work again. I’m not really sure what’s up. It’s one of a few issues I’ve had over the last few days.
@Arthur_Wolf I’m wondering if it’s the PSU as I’m also having an issue with the laser firing when I move the gantry when the X5 is off. As for wiring, I feel like maybe not since I’ve double checked it and it’s all wired as it should be and has been.
