Ethernet Cable error? Z Exceeded?
Posted: Sat Mar 08, 2025 5:20 pm
My plasma cutter stopped working in the new year and I just left it alone until now. I should have run the report and posted the question right away, but was not able to at the time and now what all happened is a bit fuzzy.(Personal life has been busy and this is basically a hobby machine.)
A little while before that I upgraded my computer and the machine worked for a while, but one day I noticed it started popping up a "452 Ethernet Communication Error, See Tech Bulletin 270" I don't remember ever seeing the error with my last computer. I saw the error a few times but things still worked fine. I noticed that when we had moved the computer that the cable looked like it had possibly been bent a bit tight. I ordered a new cable figuring I might have damaged it. The cable I ordered was from Amazon, "Cable Matters 10Gbps Snagless Shielded Cat6A Ethernet Cable 25 ft (SSTP, SFTP Shielded Ethernet Cable, Shielded Cat6 Cable, Cat 6 Shielded Network Cable) in Black." I realize this is a Cat 6 cable but in my reading I understood they were backwards compatible. Same error either cable.
A couple of cuts made it most of the way through, but then had the above communication error and a highlighted "907 Z axis travel exceeded" I tried following the recommended steps such as running the tuner program which did not help.
Now, it fails directly after the first touch off. Since the problem is now at the beginning, not just part way through the cut I thought I must have screwed something up while trying to fix the problem. I plugged in my old computer and tried that. Same issue. Either Cable, either computer and same error. In my mind that means the issue has to be in the controller or the plasma cutter.
I've attached to reports. I ran one Jan 20th, but never got to posting the problem. I've tried a few things and decided I should run a fresh report just in case I changed something without changing it back.
Let me know what other information I should provide
Here is the info about my setup:
Acorn CNC Plasma with THC (BLack)
A retrofitted 5x10 CNC Router setup made into a plasma table with SureStep STP-MTRH-34097 with DM860E Drivers (While this is not a great setup, it has been working for us.)
Everlast Plasma with CNC package
Using a float switch
