Trying to figure out what's causing this - the machine is an older PRT48x96 with the 4G upgrade. I find the 4G control board to be more intolerant of voltage fluctuations and static than my previous control board but it's basically been good having the extra speed.
On running a new file I created, it starts going to the first spot to cut and then it makes horrible noise and jumps the X rails. Even before contacting the material I'm cutting.
I've rarely had this happen and usually only when the bit strikes something or if a static charge messes up the control box and it misses steps. Nothing obvious like that this time.
Thursday it happened 3 times in a row (on the same file).
I could move and jog fine using the keyboard, so that told me the motors and control box should be OK. I didn't try a diagonal move though - just X moves.
After the second time it happened I dropped the motors down away from the rack and did a move X and found out one motor sounded slightly different. Pressing the wago connection together tighter changed the sound so I figured it was time to cut and reconnect the wiring to the wagos. I did that on both X motors on each wago (so 4 in total).
I made sure the gantry rolled smooth with the motors dropped away from the rack.
Got everything set up again, tried to run the file and got the same problem again. The file is very similar to many files I have run previously without issue. In looking at the file, there are tons of nodes but this hasn't been a problem before.
It's one design that is repeated 32 times on a sheet of material.
Any suggestions what else I can look for or try?
I will be trying another similar file to see if it continues to jump. I'm also creating another cut file for the same item and will try that too but I don't see anything unusual when I view the nodes in either file.
I'll be emailing Shopbot for suggestions also.
