Home-pos VS X0/Y0-pos

LightBurn Hardware Compatibility
1

I am using Genmitsu 4040-PRO MAX and LightBurn 1.7108 program
I have problems getting full working area. 400x400 mm
The working area I can get is 360x336 mm
It may be because my 4040-PRO Max does not have
Home position and X0/Y0 equal
X0 = 72.33 mm measured from Homepossition
Y0 = 55.33 mm measured from Homepossition

How can I get full working area 400x400 mm?
I cannot see anywhere in the machine manual or anywhere
in the LightBurn program settings how Home and X0/Y0
can be programmed as the same point.

When I read the answer by giving the console function the question with “?” I get the following answer at Home / X0Y0

Homing
<Idle|MPos:0.000,0.000,0.000,-4.000|Bf:35,254|FS:0,0|Pn:RHS>

Going to X0/Y0
<Idle|MPos:72.326,55.329,0.000,-4.000|Bf:35,253|FS:0,0|Pn:RHS>

I don’t know your machine specs, but did you check the work size area?

I don’t fully understand. Once you did the homing, the machine reports 0,0? Correct?
But if you send it to x0,y0, it will move inside the workspace?
In that case, you have an offset stored in the firmware.

Or is the zero position you would like to have moved inside the work area and you want this one to be 0,0?

Enter $# in the Console window and look at G54. It should be all zeroes. If not, enter in the Console window G54 X0 Y0 Z0 and that should clear it up.

Thanks for help. Problem solved.

Sture…

Can you share how it was solved for the benefit of others?

I was investigating how the program Candle handled zeroing of X/Y/Z.
There I found this and typed into the LightBurn console

“G92X0Y0Z0” Zero XYZ
Then “$#”
Give:
$# < [G54:-17.495,-10.000,0.000,0.000]
[G55:0.000,0.000,0.000,0.000]
[G56:0.000,0.000,0.000,0.000]
[G57:0.000,0.000,0.000,0.000]
[G58:0.000,0.000,0.000,0.000]
[G59:0.000,0.000,0.000,0.000]
[G28:0.000,0.000,0.000,0.000]
[G30:0.000,0.000,0.000,0.000]
[G92:17.495,10.000,0.000,0.000]
[TLO:0.000]
[PRB:0.000,0.000,0.000,0.000:0]
