Thanks Andy! I will try to play around and will come back.

Either way will work, there is no technical advantage of using 2 external
inverters.

Pullups/pulldowns on the 7I92T don't really matter for this specific signal
since they are overdriven by the Schmitt trigger

(the pullup/pulldown mode may matter for other signals)
 

A voltmeter will do, you just need to jog the MPG
so you can measure the high and low states.

I guess I am going to need an oscilloscope?

I would check the swing of the A,B MPG signals, relative to ground.
The input threshold is about 2.5V with ~20% hysteresis so needs a good
say 4V swing to work reliably.

Thanks mate, must have been posting at the same time.
Anyways I've added this thread to the RPi Index thread under Linuxcnc General Questions.

The 'def get_handlers(halcomp,builder,useropts):' function has the wrong indent.
It should have no indent just like the class definition.

I've noticed that some probing routines in Probe Basic change the distance mode from G90 (absolute) to relative (G91). Took me while to figure this out 

Some routines do it only when there is an error during problem while a few others always leave the machine in G91 even after successful probing.

Is this by design or is it something that should be looked into?

It does not 

 

I have been struggling to understand why my gvcp handlers are not being called. I'm running LCNC 2.9.4. Maybe I don't have syntax correct or missing a configuration item. I've attached my .ui and .py files for reference. Would someone please provide guidance?

Kind Regards,

I think I found most settings in linuxcnc.org/docs/html/examples/spindle.html
Lets see how far I get.
Only thing is that my encoder is a 2000 pulse encoder and in the example its a 100pulse per rev. encoder. We wills see...

  Hello to everybody
I retrofited two mills , one is complet functional , it work fine , Cincinna Milacro , and other one it is on demand , Leadwell VMC40.
The first is with 7i92+7177+7i84 Mesa Cards , and the second with cards from Yurtaev.com (mithsubishi) , pci card.
On the second mill , when I try to configurate the carousel for homing ,carousel  starts moving , but when I push the estop  to stop the rotate ,  don t stop !, even from desktop estop or power btn . So, I try this for the first one mill to check it ,and ,  unfortunately is the same issue.
The same is when M6 Txx  is requared from MDI , don t stop when estop is pushed , on both of mills.
The carousel have geneva mechanism , both of them with home pin and index pin .The configuration is from examples that are in Probe basic files(M13)
Any advice for eliminate the issue ?
Thanx in advance

On the bench it works.

Important is to know that the signal is inverted.
Option 1 use a second schmittriger to re invert. As example.. from 1Y to 2A and from 2Y to motion card.
Option 2 change signal in hal from in to in_not.

This is not really LinuxCNC related but something I should have done years ago, 3D-printed T-slot covers. It makes it much easier to vacuum up all the chips of the table.

 

 

It took three iterations to get the profile right, here are the test pieces I went through.

 

Here is the complete set that I installed.

 

They are printed out of flexible TPU filament and took about 4,5 hours to print on a Bambulab P1S printer.
