OK, so I recently upgraded to z-plus foolishly thinking that my z issues would be resolved entirely (which I had attributed to missing steps when milling thick stock).
After finally getting a workflow set up for two-sided milling using an aux spoilboard, I am completely baffled by the situation I’ve run into here and am hoping someone can help. (This is a variation of the vectric cribbage board project from their website.)
At first, after removing the material from the aux spoilboard I ran the gcode to “drill” the two asymmetric holes for dowels where the start depth was equal to the material thickness and the cut depth was .6". The machine cut air. I recalculated everything (in vcarve) and tried again but the same thing happened. (I did this to avoid having to re-zero Z for this intermediate step before returning the material to cut the bottom.) OK, so I opened the gcode in a simulator and confirmed that the start depth “offset” was there, and was confused, but thought OK I’ll just recalculate it from z=0 and cut depth of .6". So I saved a new gcode file without the “offset”, zeroed the bit to the aux spoilboard and then ran that program. The machine did the exact same thing and cut air. I tried both programs out of frustration and am getting the same result- cutting air (at apparently the same height). Either I am missing something entirely, or there is some issue with the gcode and carbide motion. I don’t understand how these two programs (which I verified are different using the independent gcode simulator) one with the .8" start depth and one without, are causing the machine to do the exact same thing.
I’ve attached both of the gcode files and appreciate any help as I am thoroughly confused and frustrated after I thought that I had eliminated these issues that seem to have appeared after I started using the bitsetter.3 Bottom_Profile Dowels NO MATERIAL.nc (81.1 KB) (alt).nc (51.3 KB)
