PathPilot on Parallel port

Bit of a surprise but I have Pathpilot talking to my machine via parallel port, that is it is connected and recognises the e-stop config. However I have an error I can't get rid of. When I click Ref X or Ref Y I get joint following errors on those axes. The config for the data that affects that is straight for my previous config under Axis.

I am attaching my reconfiged pathpilot ini and my original tin the hope that someone can see a glaring error or omission. Getting rid of these errors is just a part of getting it 100% working so I can replace my axis based system. Any help appreciated

Cheers

joint errors are usually down to either the logic of the switches needing inverting , or interference on the low voltage wiring , on a stepper based system

Thanks, what is weird is everything worked fine 20 minutes prior on a standard Axis based PC. I'll try a few other things today to see if it will fly .

are you using the same tormach version of lcnc
for both your axis & revised versions ?

i notice in the tormach code they are using debounce component , probably for the same reason
post your config archive and i'll run it here and see if i get the same problem

No not the same versions.... my axis install is on 2.7 Debian 64bit Jessy and Tormach uses Ubuntu 10.04 with 2.6 pre. Both hard drives are in the same PC though however the same problem existed with the PP drive in a lessor machine. I did get something happening by reducing my velocities, PP actually showed some movement on screen but no movement of the machine at all and the joint 0 following error and estop

I am attaching all my PP-ified configs I am using to try and get PP running on a parallel port. About 80% of them are straight out of my axis configs/files with what I think PP needs to run the gui. Let me know if you need anything else.

Cheers

Just another thing to note is Tormach uses 2.6.32-122-rtai kernel

Check the HAL file, it is quite likely that you don't even have a base thread, so the step generator can't possibly keep up.

You may a life saver Andy... I just checked my PP version and Tormachs and they were similar. I was just about to post about that when I looked at my original hal file and I forgot to add something to my PP version from my Axis version, namely:
addf parport.0.read base-thread
addf stepgen.make-pulses base-thread
addf parport.0.write base-thread
addf parport.0.reset base-thread

Going to fire up the other PC now to see what happens when I add those lines.....fingers crossed!

Nope, still drowning. I did actually have those lines in the PP hal file. Back to the drawing board...

Do the stepgen feedbacks go back to motion?
