Steve,

Is the pocket available on Hobby or just Industrial?

i use a head shift for different tools on the head.

mc.mcCntlSetPoundVar(inst, mc.SV_HEAD_SHIFT_X, 0.000) --head shift to 0.000 in x
mc.mcCntlSetPoundVar(inst, mc.SV_HEAD_SHIFT_Y, 0.000) --head shift to 0.000 in y
instead of 0.000 put the distance you need from the spindle to the camera
then do a g0 to the position the head was in

Mach4 General Discussion / Re: mcAxisGetMachinePos is unreliable. How do I reliably get machine coordinates?

I think all your tool change should be in machine coordinates.
I always put a g53 before movements in an atc.
Then just tell it where to go.
When the tool change is done I put a g54

Mach4 General Discussion / input to stop machine

« on: March 26, 2024, 08:18:07 AM »

We have a new machine and I am going to be putting a pressure sensor on so if the air pressure gets too low the machine will stop.
What would be the best place to put the code?
PLC Script?
Signal Script?
Any other place?
Open to any ideas.

Thanks,
Bill

I always suggest using the Feed Hold before Stop
It is a controlled slow to stop

It looks like they are closed at the drive.
You should be able to use any controller you want.

I hate to say this but you get what you pay for sometimes.
If you want true encoder feedback you will need to pay for it.
I dont know about the PMDX but I do know the ESS does not have encoder feedback.
I use the ESS and a PMDX126.
All open loop stepper motors.
If they are tuned correctly they will not loose position.
If the motors are a closed loop to the drive then you do not need a controller that closes the loop.

Then i would think one of 2 things.

Bad code in your custom screen
or
different versions of the software between the desktop and the operating computer.

If it is neither of those your guess is as good as mine.
