Duet 3 Tool Board

@tekkydave More than old enough lol and still work on kit that use SCSI Buses so well aware of bus terminations

Anyone old enough to remember SCSI hard disk? They had a SIP resistor pack in the last drive on the 50w ribbon cable.

I must be old, I remember the IDE drives and even 5 1/4" floppies...

But I never used the big 8" stuff...

Dougal1957

@timcurtis67 you never worked PDP11's then? Mind I can go back even further to the times of an IBM 1130 which used EBCDIC punched cards or a frantic Argos 500 with handlers and punched tape.

Anyone having the stp files for the 3 and 4 pin JST ZH + the 6 pin (stepper output) + the button?

I`m making a simple (not 100% accurate) ToolBoard 3D model that I can use in my designs + when designing a housing for it

I did! [Cue "You were lucky!" spoken with a Yorkshire accent].

I also remember when we asked one of our customers for a copy of their backup disks (this was before email) so we could diagnose the issue they reported. Next day it arrived by post... a perfect photocopy of a pair of 8" floppy disks!

A page with pixels and a 8"" floppy represent about the same number of bits.

Seriously, I may missed it, what are the dimension of this board?

Double sided 8 inch floppy? Luxury!

@dc42 double sided double density 1.2M

@dc42 Although I don't see a statement to the effect, I'm assuming IO0 is meant for the Z probe and IO1 the filament sensor yeah? Can IO1 be used as an X endstop instead?

Am I understanding correctly that having 4 tool boards would allow up to 10 stepper motors to be controlled (6 from the Duet3 and 4 additional from the tool boards)?

I'd say that is correct - providing those additional 4 motors are all extruders. Funnily enough, @dc42 has just posted something on his WordPress site to that effect https://miscsolutions.wordpress.com/2020/03/02/converting-the-e3d-tool-changer-to-duet-3-with-hemera-tools-part-1/

afaik the only special function is IO0 needs to be used if connecting a PanelDue, beyond that you can configure any input to be a end stop or z probe or whatever.

Yeah, that's on the main board but I know in the past there have been restrictions around having an axis's endstop on the same board as the stepper driver(s) so I wanted to make sure that if the axes motors were on the main board that the tool board's IO1 could be used as an X endstop.

Verify by trying it, but reading all the release notes, this should work.

I don't have one and can't use one if it doesn't work

I have fond memories of the 1130. I can still remember the great sounds the card reader and line printer made in unison when a coldstart card was read.

I just remembered the sound of cash registers of that era as well. Things are so damn quiet now.

I have one main board (6HC), two expansions (3HC) and four tool boards (1HC). I'd be happy to give it a try for you. If you don't mind, could you describe the "test cases" you wish to see?

That would be great! In my case, I have all of my motion (CoreXY) motors on the main board and while the Y endstop is fixed on the frame, the X endstop (actually it's a dc42 IR sensor) is on the tool carriage and senses when the tool carriage approaches the far left.

Right now it's wired back to the main board along with the Z probe, temp sensor, and extruder heater. I just want to make sure that if the IR (or any) sensor was connected to IO1 on a tool board (actually it's just an "I" since there's no "out" pin) that it will work as an X endstop.

@Danal Similar as @gtj0, I'd be interested to know if any of the inputs on a tool board could be used as an X or Y end stop (simple NC micro switch).
