Mach SDK plugin questions and answers. / Where Is The Actual Plug-In SDK?

« on: February 22, 2015, 04:48:49 PM »

I've looked, and can't find it....  I know at one point I have a ZIP file with all the documentation, include files, samples, etc.  Where is that now?

Regards,

Terry,

Except, unless I'm mistaken, loading a new program will turn off the spindle and coolant, etc., and you'll lose a lot of "state".

You can even do it with a simple CB macro, using file reads and the "code" statement.

Hi Nate,

It beats me but I think you have ruled out everything but your machine electrical's and the tuning of your servo's.
Are all your voltages correct and being maintained during the run ? - Are all your electrical connectors truly sound ?

Tweakie.

It has AC servos, powered directly off the 220VAC line, so supply power is not an issue.

What baffles me is it would have to be a problem in BOTH the X and Y drives as both are going to the wrong position.  But what would cause it to only happen on coordinated moves?

Very odd problem indeed....

Ray L.

Ray,
 Watching this run Single Step, you can see that the rough pass plunges straight in, but it stays at depth and does the S shaped lead in to the finish pass.
If I see it right.
Russ

Russ,

Yes, that is exactly right.

Russ,

That's the transition between the roughing and finishing passes.  The actual lead-in and lead-out are just straight Z moves.

Ray said this was a bed mill. Is it a commercial metal cutting mill ? Or more of a hobby level type ?
 
Just curious.
Russ

It's a Novakon Torus Pro - Perhaps not quite "commercial" level, but a big, strong machine - 25" X 15"Y 12"Z travels 1.5HP, 6000 RPM.  It's no wimp.  Same machine I use to run produfction parts for my PDBs and ATCs, and will do close to 4 cu. in/min. MRR on 6061 all day long without breaking a sweat, while giving better than +/-0.001" tolerance.

Is the 0,0 part position at the center of the square ? or elsewhere ? (at a corner)
Might try it both ways just to see if there's a difference there.
I would, but can't right now.
Russ

It's generally been off to the left, but perhaps not always.  I'll have to check.

If it’s any help to the discussion I have just been and cut two 50mm squares, one on the X-Y axis and one at 45 deg. They were both cut ‘on the line’ with a laser so turned out 49.4mm x 49.4mm but they both measure identical.

Tweakie.

Doesn't surprise me.  I'm sure this is something in this machine, or Mach3 install.

OK next test Does it cut exactly the same IF you reverse the order of cut From  CW to CCW. IS the offsetting of the cut the same ??

(;-) TP

Terry,

Good question!  I think we tried that, but not 100% sure.  I'll make sure we try that.
