Avoiding Offset Fill scorch marks

[CutAndBurnUK (Stuart Woolger)]

Just playing with the offset fill setting and I can see it being very useful. My ownly problem is the scorch marks that occur when the laser stops to move over to the next line. I’ve played with min/max power but it doesn’t seem to make any difference. C02 80watt ruida

There’s a few settings to take into consideration to tune the motion control and laser output ramping:

Confused about best approach to min power setting

On a Ruida controller (for example) the power curve representing how min and max power function relative to speed, if it were drawn, might look something like this: [image] What is important to note about this is the configuration of the controller allows for setting the start speeds (either for Line Layers or for Fill / Engrave layers). The start speed is speed at which Min Power value is used on a layer. Any movement on a layer at or below the configured Start Speed Parameter in the contr…

And (if I’m not confusing the motion control settings / layer settings on my CNC spindle) there might also be a configuration for lead in / lead out (overlapping). I’m not at my computer right now, so don’t take this at 100%.

Thanks Stroonzo, very helpful, I will have a play later.
