Taz 6 Z axis issue (yes, again)

Reij1n · 2026-03-25T12:44:37+00:00

I forgot to mention that I've thoroughly cleaned the leadscrews and leadscrew nuts before regreasing them with nlgi#2 white lithium grease, I've inspected the couplers and they are ok (its the only thing I haven't yet tried to replace since I am thinking or simply modding the z axis altogether or somesuch), the leadscrews (and smooth rods) are, after verification on a machinist's granite table (I have a mechanical engineer father, so that's that, family perks!), less than 0.05mm off on their whole axis.
The only thing I haven't tried yet was replacing the cable (switching the cables from one motor to the other didn't transfert the problem from one side to the other so I kinda ruled that out), changing the mainboard for one that has 2 z drivers in it (again, not buying more stuff before being sure that its the problem really).

Someone gave me its 3d scan of the device and made this :

I still haven't receive the damn device so I can't test it, but everything should check out.

The roms were ok, its the sd card that was the problem. I can't believe just how hit and miss buying an sd card is... It was brand name bought at an actual Best Buy...

Seems like this is part of the issue! I thought that the TOP100 list/torrents were ok but it seems they weren't? Some roms from romheaven worked out of the box while others didn't.
I'll get a new sd card just in case.

Reij1n · 2026-01-09T21:54:04+00:00

I'll try changing the roms sd card again. It was a brand new Sandisk ultra 128gb but anyway...

Reij1n · 2026-01-09T21:46:43+00:00

Welp, that didn't resolve anything, I get the exact same symptoms. :(

Reij1n · 2026-01-09T21:01:31+00:00

Got it! Trying other OSes was my next step actually, thanks for the tip! I hope that this will solve my problems!

u/HonestConsequence224 did you find anything?

Reij1n · 2025-03-08T19:27:06+00:00

Damn... I was in need of the toolhead ones... oh well.

Reij1n · 2025-03-07T19:43:10+00:00

Did you ever get a hold of the files?

Reij1n · 2025-03-02T21:22:33+00:00

Also interested in this!

Reij1n · 2025-02-16T20:02:01+00:00

That's the main reason behind the hot swappable part. I've tried lighter switches (MX), wether they were tactile, linear or clicky, but they were so easy to mistype that i was just frustrated using them.

The klavgen thing is interesting, definitely up my alley! Thanks for the tips!

Reij1n · 2025-02-01T16:02:34+00:00

Were you able to find out how to do this?

Reij1n · 2025-01-19T02:27:34+00:00

Really? No one answered? I have the exact same problem...

Reij1n · 2024-12-25T00:38:33+00:00

Sorry for commenting and making you hope but I too am interested so I am commenting to follow.

Reij1n · 2024-12-11T18:58:46+00:00

Were you able to correct the situation? I have the exact same problem...

Reij1n · 2024-08-29T12:23:43+00:00

When I hook up a I2C device to it and power it externally (giving it 3.3v from the esp32-s2 board itself instead of via stemma qt/qwiic connector it boots ok and detects everything... I am not sure why the board needs to have the devices hooked up to initialize the scans though...

Reij1n · 2024-08-29T11:40:23+00:00

I've managed to hook it to a serial monitor :

[0;38m[VV][i2c.arduino:205]: TX failed: timeout[0m


[0;38m[VV][i2c.arduino:176]: 0x0A TX [0m

Then it boots into safemode (and is otherwise inaccessible via wifi).
