Yes, you need to both connect to the proper pins that connect
to the internal hardware encoder _AND_ modify your hal file so
it uses the hardware encoder rather than the encoder component.

 That is, you will no longer have anything in the hal file that
refers  to GPIO 13 or 15 nor loadrt's the encoder component

tommylight-
The spec sheet on the opto says it's rated for 5-24V input, with a 30V max, so it should be OK. The output is 0-5V, so that should also be OK. I'll take a look at all the signals again when I get back to the lathe.

PCW-
It's been a while since I wired up all of this, so forgive me if I don't remember it all.
The 7i92 was flashed with G540x2D.bit

It appears that I mis-connected the "A" signal to the DB25 P13 / HAL 16 and the Index to DB25 P11 / HAL 14.
I'm going to move the wires around and connect them to DB25 P10 and P12 to see if that has an effect. Is that what you were referring to when you talked about Firmware?

Tormach will be more pissed, cause if I manage to do this right, it will directly compete with the 440 and 770 as a higher performance alternative if you don't need to make heavy steel cuts.

Run external script on NGC file load?

Category: Gmoccapy

Hi Guys,

I would like to run an external program automatically upon loading a file. Are there any hooks for doing with this LinuxCNC / Gmoccapy?

My goal is to compare the tools in the CAM generated file to my current tool table and make sure there are no mis-matches.

Thanks

-Jim
