Plasma CNC to launch first cut - Need help
7 Attachment(s)
Hi To everyone and Thanks to the organizers of this forum, Mechmate CNC Project.
I have recently built Mechmate CNC plasma soon going to to test first cuts. Need your help to prepare G code for floating Z axis and probe fixed CNC plasma. This is so far I achieved, Ref homing Z axis working, https://www.youtube.com/watch?v=hlvK...ature=youtu.be Testing Z axis Floating Probe without G code -- is FINE https://www.youtube.com/watch?v=D09Y...ature=youtu.be The main headache is now M899 + Probe is not working with G code. M899 is not feeling anything when Mach3 reads G code, Its directly jumping to N0140 G01 Z1.5000 F300.0, from N0110 Z4.0000 https://www.youtube.com/watch?v=Suo4...ature=youtu.be I tried to put different thickness materials to see if Probe works, But useless, Below First part of G code, Macros which dropped on macros/plasma folder also there. What might be a problem in this? I am attaching also 2-3 photos from Configuration Menu. Mach3 THC.scpost , I have also attached SheetCam post processor Please tell me where I made a mistake, N0010 (Filename: Test.tap) N0020 (Post processor: Mach3 THC.scpost) N0030 (Date: 22/08/2016) N0040 G21 (Units: Metric) N0050 G53 G90 G40 N0060 (Part: Test) N0070 (Operation: Outside Offset, 0, T1: Plasma, 1 mm kerf) N0080 G00 X56.8112 Y58.7335 Z40.0000 N0090 Z4.0000 N0100 M889 N0110 Z4.0000 N0120 M03 THIS IS TURNING THC trigger relay on N0130 G04 P0.5 N0140 G01 Z1.5000 F300.0 At This height it is cutting N0150 G03 X60.0112 Y55.5335 I3.2000 J0.0000 F600.0 N0160 X60.0112 Y55.5335 I0.0000 J9.5000 N0170 X63.2112 Y58.7335 I0.0000 J3.2000 N0180 M05 THIS IS TURNING THC trigger relay off N0190 G00 Z40.0000 Macro M899 Offset = -5 'set your offset in mm here message("Detecting of material pos.") code "G31 Z-100 F600" While IsMoving() Wend Call SetOEMDRO (802, Offset) ' Set the Z axis DRO to float head switch offset sleep(500) code "G00 Z-2.5" Macro M3 DoSpinCW() Macro M5 DoSpinStop() |
Is mach3 licenced? In demo mode THC dont work.
Edit: I watched video. With this Ivan ....... licence Mach still works in demo mode. Try with valid licence, it may make change to mach 3 behavior. |
Yeap it's licenced. I have not yet connected Plasma Source and THC's power supply.
I dont know if i can test THC's work without plasma, as I know THC works with arc. lets see I will try tomorrow, Mistake has been found with help of good master guy named Danilo, Member of this form, problem was macro named M899 supposed to be macro M889. Post processor was issuing the whole G code under M889 code. so I changed it 889, it started working :), simple unnoticeable mistake took the whole 2 days, :D Also Z axis home switch is also advised to shift up. so home position will be when torch is at the top of Z axis, that is easy I will drill another hold and shift it there, |
