Hello everyone !
I have different troubles, but I think they are all linked
My config : an home made machine used to print (3D plastic) and cut (laser), powered by Marlin 2.0 on a MEGA 2560 and Ramps 1.4. My laser is a Nejetool (model 30W). I use the latest version of LightBurn.
The laser doesnāt stop cutting between two shapes (even if LightBurn has well sent M05 command !!). In the same try, the laser correctly stop itself after the two shapes. Same problem if I add Tabs to a shape.
I am not able to use PWM on the laser. M3 or M4, whatever the value or not sent after, switch the laser at itās maximum ā¦ It seems logic because the laser TTL wire is plugged on the D4 pin. I think I should use D6, but the current is always at 1.48V on this pin (doesnāt react to M3/M4/M5 ā¦).
I have three hypothesis :
Wrong configuration in Marlin
Wrong configuration in LightBurn
Issue(s) on my RAMPS or MEGA
Do you have any ideas ?
Donāt hesitate to ask me questions if needed
Thanks for the quick answer.
Iāve done it manually, and used the āMarlinā choice.
Iāve changed my pins and I think I have a good result now !! Iāll confirm in a minute or so.
I solved the issue but I donāt understand why ā¦
I changed de PWM pin from 6 to 5 on the board and it works fine now !
I think my PIN number 6 it ill ā¦ I have to investigate. For the moment I can use my laser for the Christmas Presents !
