Yep, that's definitely the problem.  QtPlasmaC does not intend for G92 to be used.  In fact for the Master branch, we disabled it entirely:

I would recommend you use the peripheral offsets process to set up your laser pointer:

Peripheral Offsets

Then you can use the process described in the LASER section to set your origin.  The bonus is that you can use this to rotate the work coordinate system to account for a sheet of material that is not quite straight.

Hopefully that helps get you straightened out.  Please let me know if you have any questions. 

If its still of interest, the limit switches are normally closed, and go over a relay to the controls.

Setup:
LinuxCNC 2.9.0 using Axis, configured with Stepconf
Dell Precision Workstation T3500, 8g ram
Radeon HD 5700
Two identical Sunix PCIe parallel port cards
Mint Debian Edition 6
#1 SMP PREEMPT_RT Debian 6.1.128-1 (2025-02-07)
6.1.0-31-rt-amd64
Why do I have two parallel port cards? Some time ago, I damaged the MB parallel port.
This setup works great.

When I add a wifi card (TP-Link PCIe Wifi card AC600), the second parallel port card address changes (per dmesg). I updated the hal with Stepconf for the new address. Now in Axis, the Machine Power button is grayed out, like the estop circuit is open. Estop-in is on the second parallel port card, so I'm interpreting this as the wifi card is somehow blocking the second parallel port card.
I shutdown, removed the wifi card, updated the second parallel port card address, and it all works fine again.

Put the wifi card back in and ran ptest
forum.linuxcnc.org/18-computer/4743-parallel-port-tester   (thanks BigJohnT)
Both parallel port cards work with ptest, with the wifi card installed.

Advice will be greatly appreciated.

I was considering getting these drivers. Did you manage to get them to work, or should they be avoided?

sorry Snow.

1. no tried again with a different file.
2. yes, cut, then frame. its a time lapse.

I did some testing tonight and all is good until i zero off the laser pointer.
The code i'm using for this is
G92 x0 y0/ G0 x-2 y 104/G92 x0 y0

Is this code wrong?

Also, everything is fine, until I zero on the laser pointer. 

Hi all 
I need to order a 7i73 and shipping is $90 USD to get it to Qld Australia. This may be the unavoidable cost but I can't justify it for a $49usd board.
I'm happy to wait a couple of months if necessary and combine freight with others ordering from Mesa.
If your considering ordering and would like to combine our orders and split freight costs PM me. 
Cheers Brad.
