The DXF files I am exporting from CorelDRAW on the Design Lab computer seem to be clean when they import to RD Works.
I do make sure prior to export that I remove fills and make all lines hairline. Filled objects must be ‘closed’ ie, the nodes are connected all around the perimeter of the object. If they are not, the comp adds a wild line to auto connect the open object.
One thing I am still trying the get right is making multiples easily, ie telling RDWorks to make 16 duplicates of something 4x4 with a certain distance between them. I can make the field, but it wont cut them.
so @pierre and I did a quick inspection today after the workshop. The laser is out of alignment. It also not hitting in a round circle shape as you would expect. This may be due to damages mirror or lens, or hitting side of one of the mirrors on the way. We need to set a few hours aside and do a full inspection and realignment of the mirrors.
I do not think it is unsafe to continue to use the laser for now, however you may notice reduce cut quality.
