Scribing is explained in the QTplasmac manual here Spindles >= #3 can be used for any other feature that has a spindle. M3 $1 S1 = Start the scribe after loading T1 to apply tool offsets for the Scribe. Without trying to cut it, see how you can get the holes centre spotted and the inside and outside profiles cut in the Sheetcam simulation.Another spindle question - What are the spindles actually used for? At first I assumed they were used to select offsets but looking at the manual I see you need to use tool offsets as well. I set the max diameter of the holes in the drilling operation to 20 mm (0.75 inch if you are that way inclined) Here's my metric test file if you want to play with something. I suspect the intent of the original PP we followed was to allow a drilling operation with the named tool to spot with plasma (eg "Centre Spot') and would also support a drill if say there was another tool that was called "10mm drill" if a drill spindle was used. You have to use a drilling operation to locate the hole centre. I tried other methods but could not get sheetcam to move to the centre of the holes. Use a drill operation where the holes to be spotted fall within the minimum and maximum diameters in the drill operation Move holes to a new layer so they are not cut on a normal jet operationĢ. To spot the centre of a hole regardless of the tool used, you need to do two thingsġ. I am at work now and had a play in sheetcam ignoring any tools. If you don't have a drill mounted on your machine, its intuitive to me. The whole intent of using a centre spot is to drill a hole later. IMHO the drill operation should be removed as a centre spot option and kept for a drill spindle down the track. To me it is unintuitive to expect a drill operation to be a plasma centre spot.
