@zigec123

I tried everything here what you suggested but it don’t work.

You have your laser configured as ilaser. Did you try the fix in post 20 of this Topic?

You have setup your laser with the “iLaser” device type. Edit your device and switch this to “GRBL”. push “Devices” button in Laser window select your laser and then click “Edit” Change your device type and accept other settings Retest.

You do not want to be on iLaser device type. You want to be GRBL. Have you tried GRBL profile?

[zigec123 (ziga)]

YES now it works, sorry my mistake. Tnx for helping me

[clairemarvin (claire)]

Looks like you have the rotary enabled. Disable the rotary in Laser Tools->Rotary Setup.

I’m pasting the Gcode for reference.

Test1.txt (1,6 KB)

I’m using an iDraw 2.0 laser engraver (https://idrawpenplotter.com)

EDIT: I realised my firmware is not the latest (V2.08 instead of V2.09) but the firmware update provided by the laser manufacturer glitches and does not work.

Thanks to anyone who will be willing to help

@MArcoseb @nedim2501 I’d encourage you both to create new Topics for your specific issues. Your issues is likely different enough from the original that the same fix does not apply.

Please make sure to include as much detail about your situation as possible. That will help people understand what you’re facing.

[MArcoseb (Marco)]
