Engraving - in and out

[NickWL]

Using a K40 with DSP, CorelDraw and LaserCAD:

I think I'm being dumb, if so then so be it... How to I change engraving from 'innie' to 'outie'? i.e. from cutting away the image to cutting away the background?

hi there
you need to invert the image

Thanks Walt -

Thanks to Walt the innie-outie problem is solved ... only to reveal the next problem!
This is a K-40 with a complete DSP (Ligtobject's of course!) replacement control system, drawing done in CorelDRAW and fed to the machine via LaserCAD.

The x-axis keeps skipping anything from 1 to 3mm to the right, easily seen at the perimeter of this circle where it has happened several times (although the topmost 'skip' is - confusingly - to the left!). If this was on my 3D printer I'd say I was printing too fast but I'm not yet familiar enough with this system to know whether the same analysis applies.
Does it?

try to set the stepper driver to a lower setting. check your belt if it is a bit loose tighten ion the right site of the carriage

Thanks Walt - by 'stepper driver to a lower setting' do you mean the current capacity of the hardware module? Or a setting within LaserCAD?
Thanks

hi
no the stepper driver have dip switches where you select the um steps what is the name of the stepper driver??

The stepper drivers are M415B from Lightobject, the relevant DIP switches and table are shown in the attached pictures.
The first 3 DIPs are set to give a current of 0.63A.

take it down to 8 and try
