Hi all

I bought a rotating filament monitor to add to my toolchanger today, but in my haste I made a mistake in wiring. Now the coupler doesn't close on two of my toolheads.

The mistake was swapping pins 1 and 3 at the toolboard (OUT to GND). I thought I could hear the PSU fan pulsing, so turned it off and found my mistake.

Made the wiring correct, but now the coupler does not physically close on two of the tools (1 and 2). The toolhead moves to position, the screen shows C33 (from C129) and the toolhead moves away, leaving the docked tool. The screen reports the correct closed value but it does not actually move.
It does move running the macro and works correctly for tools 0 and 3.

The filament monitor was installed on tool 2.

It does still power up, and talk to the console, and everything seems ok there.

I'm guessing I've fried something, but not sure where to look first.

Help gratefully received.

I have disabled the filament sensor in config and also by unplugging from the toolboard, trying to work things out, but still no change.

@dc42 I noticed that after comparing it with another users M122. Figured I did blow the driver. I'm actually quite glad nobody said there was a silly mistake with the config.

Thanks for the offer but I've just ordered a replacement, it was my mistake to fix.

No damage that I can see, it all looks good.

@jay_s_uk Originally I didn't have the T0 at the end of config, and it had the usual "Attempting to extrude with no tool selected" error, but once selected it was ok. Then I added the T0 and it's fine once heated up.

@jay_s_uk That's made the config a lot cleaner, thanks, also took out the decimals.

M98 comes back clear of faults.

I'm thinking the driver may be dead, assuming I got lucky that everything else seems to work correctly.

@jay_s_uk Thanks, that will make it a bit cleaner.

Hi all

I've recently started upgrading my CoreXY from DuetWifi2 to Duet Mini 5 with tool dist / toolboard.

I made a bit of a boo-boo wiring the toolboard, and reversed the supply connections (24V), which blew 1 x 100uf capacitor. I replaced the capacitors with identical ones, fixed the wiring mistake and the board powers up, talks to the Duet mainboard and I've updated both boards firmware to teh latest release (3.4.3 for both).
I've been slowly commissioning the printer and I've gotten the heater, fans and BLtouch working off the toolboard.

So far so good.

I've now reached the point where I'm trying to get the extruder to work. For the life of me I can't get it to run. I'm a little lost as to how the printer knows D0 refers to the extruder E121.0. I'm not much of a programmer, I've put my config together using the config generator with a few tweaks I've seen on these forums.

When I try to extrude the paneldue shows "Busy" in the top right corner, so the printer must think it's doing something.

The extruder is a Revo Hemera, was working fine with the DuetWifi.

Worst case I'm wondering if my mistake with the power connections has blown the driver chip too. Would someone pass their eye over my config and see if I've made a mistake here? (Some descriptions are wrong as I'm still tweaking things).

Thankyou in advance.
