Heres some pics
Ahh, so my gut tells me that your tabs are milling, but you are inaccurate as to the Z zero of the top of your workpiece. You are showing 6 passes to cut all the way through. Your tabs only are as think as one pass. I bet you are cutting all the way through on the 5th pass, so that 6th pass is pointless and is cutting into your wasteboard. It’s leaving a tab in your wasteboard, but it’s a pointless tab. Just a guess though.
I’ll try it with taller tabs, I was thinking the same thing but I watched the bit on the 6th pass and it doesn’t move up and back down right there but maybe I missed it.
That worked!!! it’s out there cutting with tabs! How do I get it to power down the spindle at the end of the operation so I can set it and forget it. Quiet Cut Spindle using PWM controls M03 and M05 on and off.
Well, does M3 or M5 do it’s job normally if you just manually type it into the serial port console in ChiliPeppr? If it does, meaning you’ve got it all hooked up correctly, you just need to add M3 or M5 into your Gcode file at the start and end. Or have your CAM package add it. I suppose what would be really cool is to just have ChiliPeppr send the M3 and M5 at the start and end of the job automatically. Hmm. You’re giving me ideas!
Sounds like a winner to me, streamline things a bit.
If you do that. Please make an option to enable/disable that. My postprocessor already does M03 and M05.
You could alos open the gcode file generated from JSCUT in notepad, and add m05 as the last instruction…save that then open the saved fule in chilipeppr. I started a spindle controller widget for CP, but my workstation went up in smoke, and the move had put a damper on any progress for now.
Well, I’ve been thinking of adding a “Loop” checkbox to the Gcode widget that would have it start the job again after it’s completed. I know quite accurately on TinyG when a line is executed, and I know in a mushy way what line is executed on Grbl, so I know when the job is over. Therefore I could go ahead and hit the play button again for the user. Likewise I could add other start/end checkboxes like “Auto start/stop spindle” or “Auto move back to position … on done”
Yep… On his machine (Steve) you have to define a spindle speed to. So the call is S8000 M03 . This sets the speed at 8000 rpm and turns on the head. Then at the end its M05 and it shuts down!
