I have a simple test piece of five holes. In this case I wish to define the drilling order , and hence the path, to avoid a clamp on the stock.
I first made a path of 4 holes before realising the need, so I just added a central hole at the centre.
Problem 1: I don't seem to be able to add the fifth hole to Drilling4, I go to Base Geometry; select the 5th hole and click Add. Nothing happens , nothing in report window. Looks like a bug.
Problem 2: I made a new drilling path with the 5 holes selected in the order which I wanted them processed. The path does not seem to take account of the order the elements appear in the list. This probably not a bug but possible would be a good feature.
Should the order be significant there does not seem to be a means of reordering the elements in Base Geometry. If this has not importance and is ignored that makes sense. If would be good to order them and for it to matter.
Problem 3: probably my lack of familiarity but I selected "peck" and entred 2mm. I only see a straight dive to the bottom in the Gcode. Where is the peck?
Am I missing stuff or is this all not possible at the moment?
PS I just found another issue here. It is using G81 and it seems that GRBL does not support this. I checked that I was using grbl post processor.
