@dc42 did you view the videos they show my issues?

@dc42 yep i get an error only when i dont drop my z down after it has been homed so home z, drop z down by about 15 then set work zero then i run the g code.

Do you have a g code you would like me to try ?

Shall remove the z comands and see if it will work?

Same circle at 20mm/min is it corect that it should flick on and off? Per g1 move

https://www.dropbox.com/s/nmfwcr52qj705u3/Video 25-03-2019%2C 7 41 59 pm.mov?dl=0

Circles work ok 1000mm/min

@whosrdaddy thank you but i homed before i started just didnt show it in the video and then set the work once and then realised i coudent get a good video so moved and set work zero again. Thanks tho

Added a video hope this helps also. If you look between 20 and 30s into it you can see where i have tried to do a simple HI text and the straight lines within the text dont complete, i will do another video showing that.

Thank you

I did some more tests thismorning, the only way to get a line is for me to enter g code for every 1 mm move and the laser will fire for every line of code. This is silly to do for a straight line hope u agree. I can draw a circle with the laser as there are multiple lines of code to form the circle. Hope this info helps in some way.

@bearer thank you all working
