Pressbrake CNC Control Setup Questions

I have had a re-think, and this version of press.comp might work better. Or, at least, differently.

I am a bit concerned that the behaviour of the brake axis under homing will now be different, though.

if this doesn't work, then try setting the axis home positions to zero ( the press.axis.1.home-offset 50 line) just to see what changes.

reminder: sudo halcompile --install press.comp
 

Ok, I did some testing.
Backstop axis: If I starting homing with the home switch true, It moves at search velocity towards positive.
When it moves off home switch true and at the first index it does a very rapid jerk and proceeds with homing and completes homing. (Homing in the opposite direction resulted in a fast rapid move toward positive end of travel, not good!)
Screen Shot:
 
Also this last change causes the position after homing to be 0 right at the index, not at the point of index + home offset.

if this doesn't work, then try setting the axis home positions to zero ( the press.axis.1.home-offset 50 line) just to see what changes.

If I set it to zero homing doesn't work.
I'll keep doing more testing on my end to see if I can give you more info.
Thanks,
EW

Hello Rod:

I saw your message about the icon controller

Can I talk about it with you a little more?

Sure. You can send a message to me here.  www.vmn.com.au/contact

Hello Guys this would help me a lot as i have a old press brake with a dead old controller. Everything else is good. I know where all the pwm outputs and encoders go as well as signals for the main board, so i can deal with all pwm and IO, because i got the wiring diagrams and paperwork from the manufacturer. 

I have just  tried installing this as a simulation but didn’t succeed as i got an error when running ./bender

how would it work to run it as an actual machine, with a 7i92tm + 7i76e?

i can create a new config with this boards using pnc conf, then modify it as the ones you’ve sent right?

what i don’t understand is what does .comp do to my hal file and if i need to have done anything previously to run the installstion.


 

Can you show what error your getting?

I have not been using the simulation since my setup uses imperial measurements instead of metric.

You will need to have the press.com file installed.
From a terminal you will need to install press.comp.
Make sure the press .comp file is in your home directory, or in the terminal, first CD to the directory the file is in before compiling it.
