General Mach Discussion / Weird rotary axis issue???????????????

« on: April 24, 2016, 06:41:27 AM »

Hi All, been awhile since I've been back at the forum, may I pick your brains for some ideas with this rotary issue I'm having?
Question1.)
I've been using this machine for a few years now, it's basically a cylindrical grinder, it works in the same manner as a lathe.
Xaxis is diameter, Zaxis is left and right and A axis is the rotary head (indexable axis not a spindle).
Ever since I can remember, if I run code like the following:

G90 G0 X20. Z0.
G91 G1 A1440. F2000
      G0 X20.;***********

X axis will jump out and lose position, tripping out the servo on the line with the**************
I managed to get itto work by entering a really slow feedrate instead of G0, e.g G1 X20. F20 (very, very slow though).
I'm guessing it's to do with the fact I am trying to use the indexable axis as a spindle type arrangement, any ideas why it might be doing this???.

Question2.)
A few years back I attempted to use the A axis as both the indexable axis and also a spindle that I could just turn on and off, but I couldn't get it to work.
I tried setting the pins of the spindle to the same as the step and direction on the A axis, but I just got errors about duplicating pin assignments, could someone possible explain exactly how I could get this to work?

Mach Screens / Timer display

« on: August 26, 2015, 05:24:18 PM »

Hi Guys, is it possible to put a clock on the screen (much like the cycle run time display) that I can start with an M code when a program finishes?
It's only to display the idle time since the machine was run.......

Hi camoit,
Did you find a solution, I've started having the same issue, it was working great and then all of a sudden the error started popping up?
Mine is Win7, USB smoothstepper and the latest Mach3 install.

Hi Hood, thanks, I just tried in a VB button and it works perfectly.
I was trying in a M code which was run from within a VB button, I just couldn't get this way to work.
Thanks and sorry to trouble you.

Hi guys, I've just done the same with a virtual E-Stop, when I press the button, it works correctly by resetting all the outputs and puts the machine into an E-Stop condition, but when I press the same button, it won't clear the E-Stop, do I need to use a different OEM code for clearing it?

DoOemButton(1021)
SetUserLED(1001,0)
SetUserLED(1002,0)

BTW I'm only using a custom macro so I can reset some custom LEDs I have on the screen.

Hi Stirling,
I use the rotary axis in a profile type grinder (similar to a lathe or a cylindrical grinder, but the rotary axis is controlled via a servo motor, so I can put relief on items).
Basically it's a hob grinder.
X= Ø (same as a lathe)
Z=left and right (same as a lathe)
A=Rotation (controlled via a servo)

When I use a profile that only uses X and Z the tool path profile looks good.
If I need to use X,Z and also A rotating a controlled amount (e.g 90°) the tool path profile looks good also, if A isn't moving too far.
But if I need to have A axis basically just rotating, I need to put in X_ _ Z_ _ A3600 because it is controlled via a servo motor, I cannot just turn the rotary axis on like a lathe.
So I was hoping in this instance, I could just have the code change the tool path display to not include the rotary axis, rather than turning it on and off manually in the tool path options all the time.

Is it possible to use VB script to change the appearance of the toolpath display?
The main thing I was hoping, is to enable/disable A axis rotations.

Ha Touche!

Any chance you could elaborate on how to do this?
