While trying to get a new BLTouch working with my stock R2, I struggled to get the stock R2 firmware to work correctly with the BLTouch, and decided to give this firmware a go, since it's already BLTouch enabled. After getting the motor speeds corrected, and my z probe offsets entered, it seemed to work like a champ.
The problem I'm having now is that the printer goes for about 30 minutes or so through the print job, then blows the 3A fuse (250v 3A slow blow). I was mostly printing ABS through my first dozen fuses, and I thought it might be something to do with the higher temp requirements. So, I just kicked off a print with PLA, and it blew my last fuse about 30 minutes in.
I changed two things when doing this upgrade:
1. Added BLTouch
2. Used this firmware
I used to occasionally blow a fuse before, usually after forgetting that the motors were enabled and pushing the bed down while removing a print. I've since added the turn off all motors G code to my end of print sequence to avoid that.
So, is there any chance that this firmware is doing something that's increasing the load on the PSU and the fuse that's in the power strip? Seems like a long shot, but thought I'd ask. If not, I'll explore my fuse issues on the other thread I've got open on the topic.
