[Solved] No trigger on x after full movement, with mellow tmc 5160 pro on SPI with Octopus

I'm getting this error and the AB motors are not moving

All the pins are shorted and

What happens prior to the error? Does the toolhead move part way? Which motors do you have? Are the 1.8° or 0.9°?

[rugged kayak]

No it doesn’t move at all, only the z is running which are still on the default configuration with tmc2209

My motors are 1.8

Superpower HT frommLDO

That's a really weird error to get with the motors not even moving.

Could you post a klippy log? I'm curious if there are some other errors in there.

[rugged kayak]

Here it is

[merry charm]

Weird. There is nothing else. When you hit home then, the toolhead moves up in Z right? Then does the error pop up immediately or after some time? say 5 or 10 seconds.

[rugged kayak]

Yes after 5-10 sec

[rugged kayak]

Not immediately

[merry charm]

Silly question but is there any chance the motors are actually turning but the pulleys are not? Ie loose grub screws?

[rugged kayak]

Hmmmmm I don’t think so, it would at least have some sound or something + when I move the toolhead by hand I can hear the motors turning

Also for wiring I don’t know where is AB from the coloring but for sure the first 2 pins are shortened together (the coil) and 3 is shortened with 4

[merry charm]

Ok that sounds right then. It's just unusual for klipper to think the motors are turning when they aren't. Could you post a photo of the MCU (Octopus)? I would like to see the jumpers on the board including the jumpers under one of the 5160 boards.

[rugged kayak]

Also one more question the 5160 pro from Mellow has a dedicated AABB out

I will tag you when I come back home, thank you very much for the help

[merry charm]

Sounds great. If I am not around when you're back feel free to open a ticket in #request_help . They might find this one interesting.

[rugged kayak]

Hi @merry charm

What’s up?

[rugged kayak]

@merry charm I rewired everything to the driver itself

Not I got the signal and current running through the motor

The thing is that the driver is holding the motor after homing faild

?

[severe moat]

You rang?

[rugged kayak]

Hi

I changed to tmc 5160 pro from Mellow, and after finalizing the wiring I got a weird issue which is the motors dont move while trying to home

And then when homing faild the motors get current running in it and going to hold

And the head is not movable by hand anymore

[restive plover]

For what do you need moderator assistance?

[pearl pawn]

Hmmm. Just about to go to sleep. Why are you pinging Mods?

[severe moat]

Moderators are for when people are misbehaving. I’m about to go through airport security 🙂

[rugged kayak]

Ohhh sorry sorry, I just saw Thor was a moderator and tagged you

Pardon me guys

[severe moat]

You alerted all of us plus the admin team 🤣

[rugged kayak]

Sheeeeesh … I should tag who then, if you can help please

[warped jackal]

😂

[rugged kayak]

Sorry guys 😂😂😂

[severe moat]

Like Thor suggested, opening a help ticket is your best bet.

[warped jackal]

read thor's message about #request_help

[severe moat]

Lots of round the clock volunteer help there.

[rugged kayak]

Yeah I was about to do so

[restive plover]

Thor is probably doing that thing people do when they want to get paid. He'll be here when he can, otherwise, help ticket is a solid choice

[Closed] No trigger on x after full movement, with mellow tmc 5160 pro on SPI with Octopus

[Solution]

The Mellow Fly TMC 5160 Pro needs to have dedicated VCC GND connected to it, and also the A1A2B1B2 wires should be also connected to the board terminal, it doesn’t send the signal through the onboard terminals

This was not mentioned in the docs
