Randomly failing in the middle of a job Encoder read failure

Hey bud

Yes this is an issue I also faced. There is a long thread relating to it here 15mm error while running code - #169 by NickyD

But long story short - for me (and others) it was solved by addressing the issue of static electricity generated by the dust from the machine as it cuts. I was initially using a cheap shop vac and discovered they generate a large amount of static when the dust flows through them. So I removed the vac hose but found I still ended up with the same errors - and theorised that the dust build up in the small space I was using was also heavily statically charged.

I used spare tiny bolts to attach copper wire around the sled and earthed that wire to my house ground via the earth on my power. The made up a spay bottle of home made anti static spray (fabric softener, alcohol and water) then sprayed both the machine and the air around the space every hour or so and found that this prevented more issues. Then I also bought an anti static vac hose and earthed that. A little OTT but I have a deadline. So far so good after about 20 hours of cutting
