thanks.
Code:
cnc@debian:~/linuxcnc/configs/CNC-ANDI$ sudo halcompile --install load_conv.comp[sudo] password for cnc: Compiling realtime load_conv.c Linking load_conv.so cp load_conv.so /usr/lib/linuxcnc/modules/

percent = round(amps/0.12);

is for 12A at 100 or 150%?

I would set the 100% mark to the spindles 100% duty cycle amperage rating. some spindles have the capability to run at levels up to 150% or more amperage for short periods of time. but either way 100% should be the max continuous amperage rating allowed in the drive/motor manuals

ok thanks, my spindle is 400V 4.5kw 10A

so i set this percent = round(amps/0.10); for 100%

so my VFD has a Digital current output, i will wire this to my mesa 7i76e input.

so find found this hal code

Code:
loadrt load_conv addf load-conv.0 servo-thread # net vfd.Rott => spindle.0.speed-in setp qtpyvcp.spindle-load-indicator.max-val 125 net spindle-current => load-conv.0.amps net spindle-load qtpyvcp.spindle-load-indicator.in-f <= load-conv.0.percent net spindle-current => qtpyvcp.spindle-load-indicator.in-f # net spindle-speed-fb => qtpyvcp.spindle-encoder-rpm.in

so i must set my input pin to spindle-current?
is that right?

I´m Happy. Thanks.

I’m trying to wrap my head around this . 
I installed Linuxcnc from the main iso for 2.9.2 ,    Is that upspxe -dev?
Do I have todo any thing to my install to use load_conv.comp.  Can I just install what’s needed ?
Sorta don’t want to have to start over just for spindle load gauge since the only other thing I need todo for my machine is m6 remap.
