Bridgeport Torq-Cut TC4G Retrofit

I was thinking that when you click the CW or CCW on axis gui that there was no output at all. I did contact the new owner of the Matsurra I did a retrofit on a couple years ago and when they click either of those the spindle does not turn at all. I click them and you get an output of ~ 0.006vdc on the analog5 output and the spindle rotates ~1rpm.

From what I have found is that it has always been like this and I guess the past retrofits just did not care about the (in my case) 0.006vdc output so I never noticed it.

I did try an old hard drive I had from 3 years ago that had an old build of LCNC on it. The CW and CCW do the exact same thing as the new version. Like I said I guess I just never noticed it is all.

As far as the M19 goes... that was my misunderstanding as I never used M19 on my older machines with ATC. I always used the output of CL to exercise the orientation input on the VFD. Found that out after reviewing my old configurations and have not updated the thread accordingly. So I will take that egg on my face for that one.

On another note... getting further along on the configuration. Working out the way lube bugs now and then will begin with the ATC after I order some new prox sensors. The current ones or NPN and the 7i77 does not work with them unless I use a pull up. So I will just purchase (4) new sensors that are PNP and be good to go on moving forward with ATC.

Still owe y'all some pictures of the electrical cabinet. I will do that this weekend.

Appreciate everyone's input so far.

Read this several times by now, so here is what i think as i can not confirm any of it:
Is there an encoder on the spindle?
Is that encoder set properly and checked using halshow to make sure 1 rotation is actual 1 rotation?
On one of the retrofits i had everything set and wired and configured in hal, it would do the same thing, namely run at a very low speed when clicking forward or reverse. It was not used for anything in hal, the speed was always spot on so i did not bother with it, it is still in use every day.
The other one had roughly the same setup but the spindle feedback went to the drive and from there to Mesa boards, drive had it's own Orient logic and sensors and everything, was quite a while back so i am foggy, never used buttons but i do not recall it ever spinning without telling it the speed in gcode.
The above is not of any help, but i am out of ideas for now.
What pin is controlling the spindle, spindle-on or spindle-cv/spindle-ccv?
Is the drive 0-10V or +-10V ?

1) Yes there is an encoder on the spindle and is used only for feedback to LCNC
2) The spindle motor has its own encoder in the motor and is only for the spindle drive
3) Yes, 1rotation is 1 rotation
4) Spindle is +-10v
5) Using analog5 for output
6) Pin 1 and Pin 2 on 7i77 out to VFD which are used for CW and CCW (FWD and REV) using spindle.0.forward and spindle.0.reverse in HAL
7) Orientation for ATC is handled by the drive itself and not LCNC

The M19 orientation question I had was a misunderstanding on my end. (Lets disregard that question and discussion for now..haha)

4 and 6 are redundant in this case as +-10V should be controled by spindle-enable.
7i77 has the spindle enable separate from other enables, so try using that and leave the fwd/rew to be controled by +-10V.

I will double check the spindle being 0-10v or +-10v in a few. I may have incorrectly answered that one as I was tied up with a few things right at that moment and did not give it the full attention it deserved.

Ok, just checked on this real quick and here are the pins used on the VFD

Pin 3 = +/-10vdc
Pin 4 = 0vdc

When you mention the 7i77 has its own enable is that what you are suggesting I connect my wiring to for speed control or are you suggesting a HAL connection to something? I am figuring it is a HAL connection as enable on the 7i77 will just short out as it is a closure I thought.

Currently I have the enable lines connected to the enable circuit of the VFD. Then the analog5 out to Pins 3,4 on VFD. Attached is a snippet of the manual that shows the function of Pin 3 for +-10vdc. The VFD still requires a FWD or REV signal it seems to function.
