Bridgeport Torq-Cut TC4G Retrofit

Working on this spindle issue today and can not seem to make any headway.

1) Verified motor connections (Rotation is correct)
2) Verified encoder connections (All are good according to print)
3) Cleared VFD of all settings (Back to factory settings)
4) Verified configuration (Tried 3 known functioning configs and 1 new config)
5) Removed encoder from LCNC (Issue is still present)
6) Verified VFD is functioning from drive keypad/control panel (No issue with rotation)
Verified spindle does not move when analog5 is not physically connected to drive analog inputs
9) Verified there is ~ 0.006vdc analog5 outputs when either cw or ccw is pressed with no command input
10) Noticed there is always a 1rpm offset when watching items in hal configuration (Turn spindle on = 1rpm. Turn spindle up to 100rpm and hal shows 101rpm)
11) Tried spindle on analog4 and same issue as on analog5

Still no luck on this as of now. I will update more later as this gets worked through. As always any suggestions are welcome..

Had you previously set the spindle speed to 1 with
M3 S1?

Yes, but cleared that out with M30 and have issued multiple M3s100 commands afterwards. Also deleted my .VAR files just incase something was held in there.

I did notice that the spindle directions will not work correctly unless the following has been done:

net spindle-index-enable <=> pid.s.index-enable
net spindle-enable => pid.s.enable
net spindle-vel-cmd-rpm => pid.s.command
net spindle-vel-fb-rpm => pid.s.feedback
net spindle-output <= pid.s.output

Changed to this:

net spindle-index-enable <=> pid.s.index-enable
net spindle-enable => pid.s.enable
net spindle-vel-cmd-rpm-abs => pid.s.command
net spindle-vel-fb-rpm-abs => pid.s.feedback
net spindle-output <= pid.s.output

Without adding the -abs the spindle will not run in the proper directions and REV = FWD and FWD = FWD (Not sure there). The config was generated without the -abs. I found this by going through some old known configs from other machines I have done.

Could there be something there?

M30 does not clear the spindle speed, you would need S0 for that

Thats right... Thanks for pointing that out on the M30.

Ok, I did the following:

1) Issued a M3s100 command = Spindle went to 100rpm
2) Issued a M3s0 command = Spindle went to 0rpm (No rotation at all)
3) Checked the VFD keypad to see if FWD was still on = FWD is not on anymore when M3s0 is commanded
4) Looked at the axis gui and FWD (CW) is still on
5) Stopped spindle using axis gui
6) Pressed spindle FWD (CW) on axis gui = 1rpm rotation again.

Sounds like just a GUI +- speed characteristic if you don't have an issue
with
M3 S100
M3 S0
M5
etc
