Cutting 1/8" lite ply. 5 passes @100% power and 4mm/sec. Using same parameters in both programs.
Vendor provided software cut all the way through.
With LB cuts half the thickness. That was after 7 passes.
My gut tells me that somehow the power settings from LB do not match the actual laser 100% power. Since I am using the same hardware and different software, can’t draw any more conclusions at this time
I read some postings on here that alluded to the controller not putting out all power when set to 100%.
I believe your S value should be 255 - you’re using a relatively old version of GRBL that doesn’t support laser mode. I’m not very familiar with the 1.0b version, but changing that setting is worth a try.
Prior to 1.1f, GRBL would pause with every power or mode change, which makes engravings stop constantly, and 1.1f or later will also reduce overburn when you slow for corners. It’s an improvement.
Can’t upgrade firmware. Found out it is not compatible with laser module. Anyway, seems it is working better now. Thinking the S=255 is the real difference.
