Hi guys im struggling getting my opt laser attachment working on my CNC ROUTER PARTS[AVIDCNC] 4848PRO everything is in order as of pin config and outputs as the laser does test fire through mach4 just struggling to get a cycle to run i have been given a post processor off someone who has the same machine and laser and also uses mach but i cant get in contact with him anymore just wondered if anyone had any knowledge or a post processor that will work i am also working off Vcarve Pro thanks.

Are you usingthe M62/M63 commands for switching your laser ?
Which Motion Controller are you using ?

yes the m62 and m63 commands are in the pp file and using the ess smoothstepper.

You have probably done all this already but just in case…

For laser use Mach4 and the ESS operate at their best when used as defined pairs. The latest known working ‘pair’ is Mach4 v.4517 and ESS v.260 – perhaps check that you are using those builds before proceeding, then follow the laser setup instructions (including the macro additions) provided by Warp9 on their website.

Various Mach4 development builds can be downloaded from here;

The ESS / Mach4 laser setup details and required macro’s are here;

You can download my Vectric / Mach4 / Laser, post  processor from here; https://www.machsupport.com/forum/index.php?topic=36640.msg251176#msg251176

Hope this helps.
