Definitely a new thread (since it's a different kettle of fish) would be my vote.

I have strange things happen to me all the time.  It's kharma I guess.

I'll have to watch more carefully on the next attempt as I think the problem started after a tool change.  I may have screwed up something with the tool tip radius or ??.  I guess I posted my question a bit early as I can't respond properly yet to your knowledgeable questions.  Not sure about IK's & R's.

I think the PP I use puts out IK's rather than R's,
What problem are you having? Is it internal Arcs that are screwed?
Hood

Haven't gotten as far as internal arcs yet.  That pain is coming later.

The part I worked on last weekend had 2 external fillets.  It looked good in the P/M animation and the Mach screen with no crop circles (thanks to your G90.1 tip).  When I ran the code in Mach, cutting air, all was well until it got to one of the fillets and it arced off into oblivion, had to hit the E-stop.  I had already had other self-induced problems and wasted a lot of time on stupid stuff so didn't get much time to look into it before calming libations were necessary.  I'm at work today so will get back to it tomorrow and will have intelligent (I hope) questions to ask.

Like they say, eating an elephant is done one bite at a time.  I'll keep nibbling away at it.

Does the problem mentioned here  http://groups.yahoo.com/group/mach1mach2cnc/message/138590 apply to the latest Mach post (T_Mach3Rcss.ppr) I've downloaded from the Dolphin site?  I had a weird problem last weekend and am hoping it could be related to the arc polarity or G2/G3 reversal issue mentioned in this message.

Nah, it's just an excuse to show off all those spare drives and motors he's hoarded.

I hear there's a Discovery Channel trailer parked beside his shop....they're shooting a new reality show:  "Scottish Servo Hoarders." ®

The glass is  11.5mm thick, it is toughened and laminated glass, think 2 x 5mm toughened sheets with 1.5mm polycarb in between.

Jaysus, ya gonna stick targets on those doors & do a little target practice during long runs?  That ought'a take the boredom down a notch or 2!;)

Neat idea.
However, why not just use one disc in the QCTP, then mount a Dial guage in the collet chuck?

Dohh!  Thanks MC, that makes perfect sense.  That's why I spend so much time here: to further my edumacation!:)

I’m using an ER16 5/8” straight shank collet chuck in a QC boring bar holder to hold drills in my ORAC.  Trying to align it properly in all 3 axes was a fiddly nightmare.  Here’s what I came up with that works well.

I turned 2, 7075 aluminum discs with steel shafts to fit a collet in the spindle and the boring bar holder. The discs were made with a tight press fit on the shafts and I finish turned them once pressed together and dialed in.  It out worked real well and a little juggling with a feeler gauge and a parallel had it in very good alignment and drilling spot on.

Once it was aligned properly, I locked the adjustment down on the toolholder and added its location to Mach3’s tool table.

General Mach Discussion / Editing M3 & M4 command to add delay?

« on: March 26, 2013, 02:10:34 PM »

I can manually add in a G4 pause to let my spindle get to full speed before the tool touches metal but would rather have it done automagically in case I forget to edit the code.

I can get m3 & m4.m1s open in the VB scripter window but my 'puter-foo ends there.  I tried to look through the manual but I don't have a clue about programming.  What do I need to add to DoSpinCW() to allow a 1 or 2 sec delay before the next line executes...or is that even the correct way to go about it?
