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

@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.

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.

deckingman

@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).

To work for me would need to connect a BLTouch, Duet Magnetic Filament Sensor, 50w heater, PT1000 RTD and an endstop. Curious to know if this is possible. Thanks!

I have a fairly similar setup, so I truly understand the 'test case'. I won't be able to get to it tonight; should only be a day or two... he said...

I'm about to convert my tools from thermistors to PT100s (like a PT1000, but no amp board needed). And I have a BLt. I can test this as well. Filament sensor will work on an IO port, and heater will work, those are pretty inherent to a tool board. Again, may be a day or two.

Would the BLt be your Z Probe? The switch endstop, for what axis is this?

Yes to all.

It should be possible to use the temp1 pins to connect a switch-type endstop, but I'll need to check whether the firmware supports that.

The combination that doesn't yet work is using an endstop switch connected to the main board to stop a motor connected to an expansion or tool board, when the same axis doesn't also have a motor connected to the main board. This will be fixed in firmware 3.02.

Ah, the reverse case. Thanks David.

@Danal If you still have time to test that'd be great but not so urgent, for me anyway.
