Announcement: Duet 3 Toolboard revision v1.1

droftarts

@khenderick Schematics are here, if you choose the hacking option:
v1.0: https://github.com/Duet3D/Duet3-Toolboard-1LC/blob/master/ToolBoard_1LC_v1.0/Duet3_TB_1LC_Schematic_v1.0.pdf
v1.1: https://github.com/Duet3D/Duet3-Toolboard-1LC/blob/master/ToolBoard_1LC_v1.1/Duet3_TB_1LC_Schematic_v1.1.pdf

You don't have to miss out; you can connect the accelerometer to a SAMMY C21 board (and connect that to the Toolboard CAN) or direct to the mainboard.

The v1.1 tool board schematic linked to above isn't quite right, because the board are modified during production:

the INT output of the accelerometer is no longer connected to PA19 of the microcontroller;
INT is instead connected through a silicon diode to PA00.

@dc42 I saw that one guy on twitter made a back toolboard 1.1 Where did he get the gerber files from?

@pcr he did not get the gerbers

@t3p3tony Sure?;) Looks Not Like diy

@pcr I am sure Brendon or I will explain at some point

I wanted the new revision, even though I am hardly at the point I understand everything I need to do before input shaping, with that even a version away and my existing boards aren't even a few months old.

But it turns out an easy decision to replace if you just forget to power the board down while doing some adjustments, slip with a t-handle hex and somehow manage to touch two things that shouldn't be touched.

As the boards red light disappears never to be seen again, a gingerly walk to the computer for the local parts store where its already been confirmed they have a v1.1 in stock.

It arrives in slightly more than 4 hours, unless it doesn't, but lets not think like that.

@droftarts Thanks. Seems it will be hard to patch an accelerometer to v1.0 unfortunately. That might be a suggestion for a future revision; make the I2C pins available on test pins.

Adding a Sammy C21 will be more realistic. Without highjacking the topic too much; having a toolchanger, would adding one to the toolhead make sense, so it would be used for / shared by multiple tools? Or would supporting such thing in the firmware be unlikely?

@khenderick adding one to the carriage should be sufficient

I suggest having one that you can move between tools. However, if all the tools are the same (e.g. all Hemera with standard hot end) then they should all have the same resonant frequencies, and you should only need to calibrate input shaping for one of them.

I write here not to open a new post.
Is it possible to connect an inductive probe (Omron TL-Q5 NPN ) powered at 24v to the IO_3in port of a 1LC v1.3 board?
How many voltage does the IO_3 port tolerate?
