General Mach Discussion / Arc's in planes other than G17

« on: March 22, 2010, 05:54:28 PM »

Trying to program a helix in G18 (which would be XZ plane, axis of arc parallel to Y axis).  An example of the code would be:

G00 X0.375 Y0. Z0.375
G18
G02 X0. Y0. Z0. I-0.375 F10.

IJK is set to incremental, and I do get an arc on the toolpath display.  However there is no difference shown between G02 and G03. Both would generate what would be a CCW arc.  Now it's entirely possible that I missed something stupid, and I did try multiple computers with multiple profiles and the issue repeats itself.  Although I mentioned cutting a helix, which is the end goal, I have cut back the code to just get an arc to cut.  I also tried with R values. 
I know arcs (let alone helix's) in planes other than G17 aren't that common so maybe this hasn't come up before.

General Mach Discussion / Shuttle plugin won't go away

« on: November 18, 2009, 09:47:01 PM »

I've been doing a lot of tuning with my Mach system lately, and getting very positive results.  I am using the latest available build Mach3 R3.042.032  with a Smooth Stepper and a G540, latest plugin for that as well. Thing is, every time I start Mach3 I get a message flashed about there being no Shuttle in the system, I go to plugin config and disable the Shuttle Plugin,  and do a Save Settings, but the next time I start Mach there it is again.  I would really like to be able to permanently disable this, and I'm not sure if I need some of the other ones as well.  Is there a way to get rid of this plugin, or at least make the setting stick?

General Mach Discussion / MPG Behavior questions

« on: April 08, 2009, 03:26:50 PM »

Ok, my goal is to build a pendant that imitates some functions of the HAAS machine I used to work on.  I am trying to figure out how the MPG will behave when used here.  On that machine you would select buttons to determine the movement per step, 0.1", 0.01", 0.001" or 0.0001" per "click" of the wheel.  Similar to the way mach lets you cycle through these in the Step Jog mode.  The wheel has 100 detents and corresponding marks on the wheel. 
I've read the Mach3 manual, but I don't have hardware to play with yet, but can Mach3 be set up to work like this?  One "click" of the physical wheel makes one step in jog mode?  From what I read, it looks like you just set up the wheel to make the machine move, but it doesn't work with step mode.  Or am I way off here?  Thanks for any help anyone can provide?
