Planning - Bridgeport Interact 1 linuxCNC Retrofit

Looks like good progress. Are you using the trigger function on Halscope?
You probably saw this thread: forum.linuxcnc.org/forum/49-basic-config...ervo-tuning?start=20
Back in 2012 a guy did the same refit that we are doing and found a 6ms command to movement delay that is probably in the servos. I found the exact same issue and my tuning looks quite similar. The results are acceptable but not ideal. I found that lowering the MAX_ACCELERATION to 4 helped a lot with the spikes, but at the cost of speed. There was no follow up for the thread so there probably was not a better resolution to the issue.

Yes while tuning I'm using the auto trigger of the scope. I set it to rising edge on my command signal.

In that thread you pointed out (I had read before), PCW did suggest inverse deadband and might help.
I wonder if anyone has implemented it before. Well I'm sure someone has, I'll try researching it.

Here is the link

I have not tried inverse deadband yet, it's on my list. I am a little sceptical that it will help, but figured it's worth trying. I spent a lot of time searching for more information and found very little.

I might have a go at reverse deadband, if so I'll post the results.

Here is an image of me placing my components into my pendant.

I mounted it this way because on the back, I'll have a hinge and spring loaded cables. That way I can access everything directly from the rear.

I'm not sure if I'll leave the plexi clear or not. I might paint it.

Ive ran into a snag I cant seem to figure out.

I'm trying to link my joystick commands to jog my axes. The outputs are 24v to the 7i77 via input TB8 pins 06-09. However I am getting no movement and looking through HAL configuration, the readings are false. Ive connected the pins via PncConf Wizard.

I haven't started tackling editing the hal file yet.


Ive posted my hal and ini files below.




Im reading up in the DOC's at the moment. Any help is much appreciated.

If you can't see any action on the hm2 input pins when you move the joystick then it is probably a wiring problem. How is the joystick connected? Perhaps the joystick connects pins to GND?
