Interference or noise causing small changes in jog

CrossFire ® Troubleshooting

anyone having or had a issue with jogging lock up?
every once in a while during a jog between cuts or when going to 0,0 one or both drives will lock up. sometimes not detectable to the ear, but up to 2.00 off on cut location. I have disassembled everything and it even happens with just the stepper alone.
after making sure all parts are free and no binding issues (including the coupler screws), I have found a way to make it happen. Just opening a web browser is enough to lock up both steppers.

file is break-in jog end to end

I have reached out to LS and am getting good responses. I just want to see if you’all know an easy fix, like airplane mode (failed)

you may have a fast processor…but your RAM is pretty low to multitask I think.
I run 16G in my laptop of ram and I can surf youtube and watch videos…and still cut…my old desktop was around 4 and it did what you showed…

This is interesting. I had wondered about multitasking while cutting. I don’t do anything else with my laptop while cutting, perhaps thats the solution?

SSD and the 16gb…should do it…

remember when we all thought 64k was great memory on a PC…and had the old floppy disk…or the tape drives…

Double sided could store a whopping 500K bytes and it really was ‘floppy’!

My first computer had a 20MB hard drive and 2 of the 5.25 floppy drives

It looks like it was the computer that had all the issues. I have not had a glitch with the new laptop.
I want to thank the people a Langmuir Systems that helped with emailed tests, by finding out what it wasn’t, the computer was the only thing left.
Now just to connect a new torch relay and I’ll be cutting away.
Thanks everyone
Bob
