@terjeio any updates on this issue? This is an example with 1 mm cut, clearance, last pass 45 degree taper:
G18 G8 G21 M3S100 G4P1 G0 X6.000 G0 Z0.500 G97 (Pass: 1, DOC: 4.000 1.000) G1 X4.000 F200.000 G1 X5.000 Z-1.000 G0 X5.000; // THIS LINE SHOULDN'T BE THERE ! G0 Z0.500 (Pass: 2, DOC: 3.000 1.000) G1 X3.000 F200.000 G1 X5.000 Z-2.000 G0 X4.000; // SO THIS! G0 Z0.500 (Pass: 3, DOC: 2.000 1.000) G1 X2.000 F200.000 G1 X5.000 Z-3.000 G0 X3.000; // AND THIS! G0 Z0.500 (Pass: 4, DOC: 1.000 1.000) G1 X1.000 F200.000 G1 X5.000 Z-4.000 G0 X2.000; // THIS ONE TOO! G0 Z0.500 (Pass: 5, DOC: 0.000 1.000) G1 X0.000 F100.000 G1 X5.000 Z-5.000 G0 X1.000; // At this point it will be 2 mm rod instead taper... G0 Z0.500
Without fix, it cut taper, then at the end of this taper it moves cutter to the center. This is a bug to use taper minor diameter to calculate clearance, taper major diameter should be used. Or it shouldn't be used at all since it unnecessary - when we move Z to start position, it immediately clear from part because of taper.
Not yet, I have been quite busy with private assignments lately.
I have uploaded new edge versions for you to try - when a taper is selected only current and target diameter is used for the calculations - and Z length is calculated as well. I have also enabled entry of fractional degrees and I flag an error if the angle is >= 90 degrees. I have not yet implemented/verified internal tapers and the UI could be improved.
What do you think?
Looks good now. How it used to be, you can check there: https://youtu.be/5Wq_Iub6t_M?t=272
Hi @terjeio, could you try to cut taper? But with real part please :)
There is a problem in this line: https://github.com/terjeio/ioSender/blob/614115d80c1f6c792112371e94f73741558cc407/CNC%20Controls%20Lathe/CNC%20Controls%20Lathe/TurningLogic.cs#L181C1-L181C100
It should be like this(see the comment):
I almost ruined the workpiece because of that. I actually ruined it anyway, but it completely my fault.
