G-Code, CAD, and CAM discussions / Re: Strange tool offset problem

Your right on there   A year ago I didn't know how to run a CNC  and now(thanks to this forum and a bit of insanity) I have rebuilt one.  I'm just trying to work out the last few kinks.   Thanks for the info,  now I can play with the post and see if I can make output something similar.

Thanks agian,

Tom

I've tried it both ways with the same results.

Shouldn't the G44 do it?...

Thanks,  I tried your suggestion but it still does the same thing.   It seems that for some reason Mach isn't automatically recognizing the Z/tool offset.

OK thats not it,  I think I am missing something simple.  here is my work-around,  start the program>Asks for tool>then I go to offsets, Tool Offset led is on but the DRO is wrong, I turn it off and it changes the DRO, I turn it back on and it is correct, I go back to the program screen and hit cycle start and every thing is fine.

  any Ideas

Thanks

I am running MastercamX and am using the post found on this site for Mach3.   I have all my tools in quick change collets and have them all ref.  But whan I run a program it ignores the tool length offset.  From reading here and the manual it seems that the post processor isn't putting in the H~ call out for the tool # after the G44.  Can some one please help.

OR I am missing something....
I am running the latest lockdown

Thanks

Yes I have and am getting good penetration.   I have read that you set these up(real ones anyways).   is there any data on feed rates?  I just guessed until I got it right.   It seems as thou you could up the wire speed in proportion to travel speed... is this right?

Thanks

It's working great!  here is some pics of of the set up.  I'm useing 3/64 wire with a travel speed of 70 ipms.  Tacks and welds both "legs" in 1 min!!

Did some tests and they look pretty good.  Will be doing the actual parts next week.

Looks great Apples!  I'll be doing my samples next week.  its 1/4 inch aluminum 6 feet long,  do you think I should tack it first by hand or just go for it?  Well clamped?
