So this is a new one for me , during a cut my Z axis tends to jog up on its own messing up my cut. And solutions ?
Some of us are trying to ask lots of questions and get all the details up front so that none of us are surprised.
The more information that you can supply, the better we can try to help. We need this:
• any recent changes: new electrical equipment, generator problems, circuit breakers tripping, flickering lights
• CAD program used
• CAM program used (SheetCAM or Fusion 360)
• metal thickness/type
• work lead attached to shiny/clean metal
• work lead, torch cable, THC cable and printer cable to the enclosure are not touching/crossing paths nor coiled up
• copy of the gcode of your test file
• photo of how your torch is mounted
• photos of your consumables
• What plasma cutter are you using? Are you using OEM consumables? Are they standard or fine-cut consumables.
• What is the brand of the consumables (not the machine they are labeled for)
• air quality and quantity (pressure gauge at the plasma cutter), what methods of drying employed. You need 6 CFM @ 90 psi and it needs to be dry.
• Smart Voltage on nominal voltage
• Have you had any successful cuts with the current setup and metal type/thickness?
• Can you fire the torch manually thru FireControl?
• Are you couplers tight?
• Is there any connection issues with the IHS contacts in the z-axis carriage?
• Have you lubricated the lead screws?
• Are you using a laptop and is it plugged in or running on battery only? Battery fully charged?
• Cut height: have you measured what your cut height actually is when you set it at 0.06 inches for normal consumables or 0.14 for Hypertherm SYNC consumables?
Meanwhile, you could check out this thread. Maybe it will give you some clues:

I came across a post on here the guy didn’t have the same problem but what he did was re wire all the connections in the z axis eliminating the butt connectors that was causing a lot of interference. I did this today and have not had it jog up on me.

Excellent! Keep us posted.

The IHS circuit is a normally closed loop. Any loss of connection in those wires is going to tell Firecontrol that the IHS switch is open. As a safety measure, Firecontrol will lift the Z axis by .060" any time that connection is open during a cut.
