Wrong position during vector laser cut #955

Closed mdeel-online closed 4 years ago

mdeel-online commented 4 years ago

Hello, at first... sorry for my bad english

I have a new toy. A Totem Laser engraver and i have one Problem only at vector laser cut. I hope you can see the problem and know what i mean. The laser does not move to the right place during cutting. It just starts in the middle. I don't have the problem with normal operations. 20200415_172736_resized 20200415_172811_resized 20200415_172820_resized 20200415_172828_resized 20200415_172849_resized 20200415_172855_resized 20200415_172925_resized 20200415_172931_resized

I have found the cause and here it is explained in detail. Please note that the first G0 code must remain on G0. Otherwise the switched-on laser moves to the starting point

Now the question is to activate the old commands in the Lasergrbl?

It looks like I have the same problem ... but why only few people face this ... as everyone use the same LaserGRBL. and arduino load ?

@mdeel-online.

I noticed in the images you posted of your GRBL configuration you don't have Laser mode enabled ($32). In grbl menu, grbl configurating change it to $32=1. You can read what it does here: https://github.com/gnea/grbl/wiki/Grbl-v1.1-Laser-Mode

Also $120 and 121 seem a bit high for Acceleration. If it's too fast it can lose steps.

Perfect thank you thats the Problem. 120 and 121 works fine at value 2000 and 32 its on now. Great Help from you!!!
