G-Code Export doesn't work on ESTLCAM with LightBurn 1.7.08

Hi all,

it’s my first time to write a forum entry, so please don’t blame me to much :wink:
If you feel it is garbage, just delete it.
Could be similar to " G-Code Export G90?"

I use a MPCNC selfmade router /milling machine with ESTLCAM Firmware (Perfect Software for me using a router)
With version 1.7.07 G-Code export worked fine on ESTLCAM CNC.
With 1.7.08 ESTLCAM CNC didn’t load the g-code.

ELSTCAM from version 12 on needs all 3 axis “introduced”.
Difference is as follows
In version 1.7.07 the G-Code was as shown here:

; LightBurn 1.7.07
; GRBL-M3 (1.1e or earlier) device profile, absolute coords
; Bounds: X-0 Y-0 to X163.12 Y131.64

;USER START SCRIPT
M05 S0

;USER START SCRIPT

G00 G17 G40 G21 G54
G90
; Cut @ 800 mm/min, 15% power
M8
M5
G0 X14.92Y10.092
G0 Z0
; Layer CUT

In Version 1.7.08 it ist like that:

; LightBurn 1.7.08
; GRBL-M3 (1.1e or earlier) device profile, user origin
; Bounds: X0 Y-0 to X163.91 Y134.64

;USER START SCRIPT
M05 S0

;USER START SCRIPT

G00 G17 G40 G21 G54
G90
G0 X0 Y0
G91
; Cut @ 800 mm/min, 15% power
M8
M5
G0 X-15.603Y-10.164
; Layer CUT

You see that G0 Z0 is missing, therefore, ELSTCNC denies loading the G-Code
so I added in the machine settings, tab “g-Code”

G0 X0 Y0 Z0

looks like that in the exported g-Code:

;USER START SCRIPT
M05 S0
G0 X0 Y0 Z0

Now it works again und g-Code ist loaded and cutted in ESTLCNC

Hope it helps others

Do you have your z axis enabled in device settings in the new one?

Yes, as in the previous version.
And I tried it with "relative z-movement " as well.

Hi Ralph

After checking with the Dev Team there should be no changes that could justify what you are experiencing.

Would it be possible to
a) File > preferences > Bundle. Export your settings bundle and send to support@lightubrnsoftwre.com

b) Open your Device settings (Edit > Device settings)
Uncheck “Enable Z” and click OK
Then Do the reverse, Enable Z

Try export Gcode again please?

Hello Ralph,

im using Estlcam with the Estlcam Klemmenadapter on my own for about 1.5 year already.
I was able to recrate the described behavior.
The differenc is, you used absolute coordinates in the first sample and user origin in the second one.

If you have any more questions about using Estlcam with Lightburn feel free to ask.

First of all !!Great Support!!!
Unfortunately no change in preferences has taken effect.
Therefore, I deleted the pref.ini
After that changes in the Settings Dialog took effect again.

I will send my current settings tomrrow.
Z still not working, except I apply my workaround.

Hi Ernest,

thanks a lot. I will definitely come back to you. Meanwhile I bought the OPEN CNC Board V2. Here I have the possibility to switch between 2 controllers.
One flashed with ESTLCAM Firmware, other with GRBL.
Unfortunately I had have no time to install it till now.
I can report back if you are interessted.

BR

Ralph
