Hi to all!
I buyed piclaser for make photo engraving and i have some problems with feed rate when i send Gcodes generated with Piclaser.
I set my CNC to 4000mm/min feed rate and when start a job make outline fast but when start with photo slow down drasticaly.
Whit my Nichia 2.5W Laser i need more speed or all parts of job it's dark and i need to put down laser potenci with max laser value to 100
I use the last GRBL i think is 0.9J and now i use this config (i changed a lot of thing for try to improve speed):
In pixel resolution y use 0.16mm because with 0.18-0.254 the lines are to many separeted and my laser focus i think it's good and small focus point.
I use CNC Shield and use spindle pwm with S commands for control pwm.
Any idea for improve speed when print rasters?
Thanks to all for your help.
