BeagleBone Black saw length stop

Hi guys. I’m looking for input on this project. Any help is hugely appreciated!

I’m in the planning phase of building an automatic length stop/pusher for my cold saw (later on I’ll start working on further automating the saw but for now the length stop is enough).
Something like a Tigerstop is what I’m going for (see video)

I’ve got a good handle on the mechanical aspect of the build.

What I’m looking to accomplish is two modes

Absolute mode work flow:
• punch in a position for the carriage (stop) to travel to,
• operator clamps the material
• cut
• unclamp
• remove piece
• punch in new position
• repeat

Push mode work flow:
• Load material
• End trim cut
• Punch in cut length
• Carriage pushes material to length + saw kerf parameter
• Cut
• Unclamp
• Punch in new length
• Carriage pushes material to length + saw kerf parameter
• repeat



This is what I’m thinking of using for hardware.

The machinekit port for the BeagleBone.

Thanks for any and all input!

Thanks Andy.

I think the Glade GUI and Python sounds like a good idea.

One other idea: Could a NGCGUI macro work to enter a single cut or a short list for a single piece of stock and then basically run in single line mode? ala your lathe interface?




Thanks for your input!

Just use MDI commands, so you can enter as much as you like. If you need to change matirial, just give an M1 comand.

Thats all.

Sorry to revive/hijack an old thread, but I want to build a gui for doing this very thing.

I am curious if the fellow who started this thread ever got anywhere with his project?
