Re: Mach2 lathe, Steve and Art

Hi,
Somehow I'm missing the usefulness of all this touchoff stuff. Can you explain how it is different from just clicking in the DRO and entering the position you know you are in, ( Work Radis plus guage thickness)?

Hi Art,
Thanks, but in the example of running at 2000 rpm with the Z axis needing to move at 100ipm, it would take only 1/100th of a minute to cut a one inch long thread. I haven't done any calculus for a long tome but it seems to me that I'd have to start way before the thread and the deceleration would still ruin it. If I'm right what kind of Z axis acceleration would one need to be able to cut at that speed?

I am looking into the spindle now, but I was wrong about the offsets. Or at least mine seems to work. Try this in this sequence. Put in a piece of stock. Jog to the edge, If the stock is 30mms thick, type 30 into the Touch Correction box and turn it on. The LED shoudl flash. Now press Touch X on the Fixture offsets at the bottom. Does the display on X now read 30? Now jog to the face of the stock with the Z (and X if you have to). Type in the length of the stock (say 124), and enter 124 in the touch correction, now press TouchZ on the fixtures offset down below. Does the Z readout now say 124? If so you are now zeroed to the stock. This is the method to zero all this. Let me know if this example does something different to you. Now, as to some of the strange stuff happening to you.... N30 G0 X20.0 Z40.0 ' Tool change position N40 M6 T1 ' CHANGE TO TOOL # 1 N50 G43 H1 Line such as N30 and N40 are screwing you up badly. Having a ' in the line causes the interpreter to ignore the entire line. the ' character is illegal or can be translated to "This line is a comment", so your M6T1 is being ignored as is your G0X20Z40 line. This will cause the G43H1 to react very badly because it will think you are (and you would be) at 0,0, not 20,40 See if the touching off works after you remove the ' characters. Thanks, I'll let you know about spindle. Strange thing is, if the LED is flashing, then it MUST be on. Or so I thought. Check your pin settings on this while I check the code.

That may be causing a transverse to 0,0.Worked fine up to now (sort of ;) There doesn't appear to be a standard "lathe syntax" Fanuc 6TM is T00<TOOL>00 Fanuc 20TAM & 21ITM is T<TOOL><OFFSET#> Okuma OSP5000 <TURRET>T{<COMP-NUM>}<TOOL><OFFSET#>{<TRT-TURN> etc, etc. It only does it at the start of a file, not on subsequent tool changes, Art has pointed out that offsets are screwed, something else I noticed is that tool offsets are being included on the display screen so the part looks nothing like it's supposed to. Tool offsets are now saved for lathe & mill separately though ;) Hard to tell what else needs sorting until spindle will run from Gcode. -- Steve Blackmore |

The profile should not have overwritten, but I have seen instances where the system overwrites anyway. ALWAYS backup your .xml files before installing a new version. Sorry, Art www.artofcnc.ca ----- Original Message -----

Re: Ok, What's the trick to installing Mach2 special driver for non-apic b

I have the latest driver, I downloaded it at the same time I got RC10. As I said in another post, I even went so far as to re-install Windows 2000 and I was still getting the BSOD when I tried to start Mach2 or the driver test program. I will try again this evening. I had to deal with a very upsetting family matter this morning so the last time I tried it failed but I am sure it was my fault. I will make sure I pull every thing down again when I get home and go from there. Life would be so much easier if I had a motherboard that did not require the special driver! Thanks for the reply.

John:
Whenever you get a "wrong driver" message it means the driver is too old or too new. In RC10, you MUST re-download the special driver for non-apic boards again. It was updated at release time. If you get this after downloading let me know. Thanks, Art |

Steve,
I'm not sure but aren't you using the mil tool change syntax (M6 T1) instead of the lathe syntax (M6 T01xx)? That may be causing a transverse to 0,0. Just a thought.

Re: Thread picture uploaded
Art,
Seems a good assumption for all but tapered threads. Comsider pipe threads: If cut "backwards" and "upside down" (which is common for many threads, especially blind types) using constant SFPM, the spindle will increase in speed as the diameter is decreased... Just a heads up... (probably can "fix" it with a "Don't do this"<G>) Ballendo --- In mach1mach2cnc@..., Art <fenerty@a...> wrote: LatheHeads...The design assumes the spindle will not speed up above the starting RPM during a thread (hopefully a goodassumption) so time |

Ok, What's the trick to installing Mach2 special driver for non-apic b
John Guenther
Art,
I have tried several times to install this driver with RC10, I even went back and completely reinstalled a fresh copy of Windows 2000 and I still get the blue screen of death when I try to run the driver test or Mach2. I had this working with RC7.1 but RC10 complained about using the wrong driver so I thought I would remove and reinstall it. Well, that did not work for me so I have now reloaded Windows 2000 and it still does not work. What have I done wrong? I believe I have followed the instructions in the manual exactly but I must be doing something wrong. Any help from you or anyone else will be deeply appreciated.

Mach2 RC10 lathe major bug
Steve Blackmore
Spindle & coolant do not appear to work from within gcode
Type G0 X10 Z10 M4 M8 G0 X0 Z0 M5 M9 in MDI and they work, spinle enables at correct speed and turns on & off, as does coolant Copy the above into a text file load as Gcode and run, X & Z axis moves but spindle and coolant pins are not enabled although diags flashing leds saying they are?? -- Steve Blackmore |

Mach2 lathe
Steve Blackmore
Thanks Art - display is much improved! With my current spindle speeds
theoretically I can do .45mm pitch threads at 2000rpm, which is fine for me. I haven't tried it in anger because of the following: I still have the positioning problem, you wrote previously The touch off, should be done in your example by entering 30 in the touchWhich is very confusing - the diameter stated in my original mail was 10?? Length was 30. I've tried several ways this morning to get it to understand the diameter and length but it still wants to go to 0,0 first before going to tool change position at X20 Z40. This causes the tool to power into the work! Using the example Taig collet file I sent you how do I get it to accept the actual corner of the work is Z31 (the extra 1 is for facing pass) and at X7.5 (work dia is 15) If you do the offsets you can see the tool moving to 0,0 before line 30! Here's the first section to tool change % 'tcollet N10 G21 N20 G90 F53.34 S700 M5 N30 G0 X20.0 Z40.0 ' Tool change position N40 M6 T1 ' CHANGE TO TOOL # 1 N50 G43 H1 It may well be me being stupid, but can someone carefully, step by step, talk me through this please! -- Steve Blackmore |
