Think I used the attached stl file (EBB36 mount for VZBOT Printhead v2.stl ) for the Fly mount and this for the UTOC. The cover I modified to fit my setup. I include the modified version (VZBot SHT_EB_36 Cover_Logo and Motor Cutout.step) and a link to the original file. (This has the Voron Logo though)

           

Shout out if you need anything else.

And you'll find the conversion will be a breeze

Thank you good sir.

Disaster Strikes!!

Whilst fiddling around the back get ready for the next upgrade, this happened.

 

Upon closer inspection, it looks like the USB socket securing tabs were badly soldered to the board. Both of the securing tabs show no signs of being soldered. The only things that were keeping the socket on the board were the 16 micro sized contacts.

Fortunately I have a spare board in my stash, and I had backed up most of the config files. Unfortunately, I forgot to set up the github back up for the Vz.

You should be able to swap out the controller without affecting anything that's loaded on the Pi. You should only need to flash the new controller.

Good tip thanks.

I never thought about that.

@TitusADuxass How are your solder skills? Straighten the pins on the USB C connector, clean the soldering pads on the motherboard, including the retaining tab pads, apply flux, and attach the retaining pads and then the pins one by one. From your photo, it looks like none of the motherboard pads are damaged or pulled. You'll need a fine tip on your soldering iron. If you're not comfortable with repairing fine someone with the skills to do so. This is an easy fix for someone with the right skills.

My soldering skills are okay for normal sized wires, etc. 

I couldn't keep my hand still enough to do this.

@TitusADuxass This repair is also best performed under a microscope as well. Find someone who does PC/laptop board repairs. Not sure what the shipping cost would be to Canada but I'd gladly do the repair for you.

I think I have found someone locally who does this sort of thing.

Sometimes the repair ends up being more expensive than a new board.

FWIW... You can get a hot air soldering station for ~$40 US on Amazon but then again... that will probably drive the cost of repair over the cost of a new board.

[TitusADuxass]

I've raised the issue with Mellow on their Aliexpress site.

I don't hold out much hope.

[TitusADuxass]

@Penatr8tor Back up and running now, thanks for the tip.

Sweet!

I had a problem with a Pi4B not too long ago and just swapped the board and used the same SD card... New board just booted right up.

Good to know it worked for you.

[TitusADuxass]

I contacted Mellow through their AliExpress page, they got back to me very quickly  - a new board is on its way to me.

And, the local repair shop said they can repair my old board for Ca. 25€.

A Good outcome all around

If it were me... 

I'd also pay the 25 euro. I mean why not right?

I'm sure you're already thinking the same thing.

Seeing a company standing behind its product and quickly solving an issue is nice.

I am, it's going in for repair on Monday.

[TitusADuxass]

So I went to "der Reparaturladen" (repair shop), he fitted a new USB C socket straightaway for 20€.

Sometimes the planets align in your favor. 

[TitusADuxass]

But all is not well with the 330, this should be a cube!

It looks like I've got a bit of work to do on the weekend.

They don't align the way you think they did.

Yikes!! - Some layer-shifting there alright! And it seems consistent towards negative X. Belts? Some binding? Loose motor gear? (You know we get warned about using that blue stuff on grub screws)

It could be a motor syncronisation problem, a motor and belt check is first on the list this weeken.

[TitusADuxass]

The motors were not out of sync, but there is a problem.

When I home all everything is fine.

When I home X and then Y (or just X or just Y) and then try and move the toolhead along in 10mm steps I get a Must home axis first error (for X it occurs after 30mm, and for Y it occurs after 50mm of movement).

The error is consistent, but only happens when I individually home either X or Y.
