You need a zip tie on the head (extruder)

[Fabio]

I received my Sovol Zero, calibrated the filament (PETG High Speed) and printed some things, all ok.

Then I printed Benchy, which came out pretty good indeed (for a 8 minutes print):

It finished without a problem.

However, I started a new job and I heard terrible noises while the Zero was trying to home the head:

The problem (tip code 101 y) is that the black (electrical) cable is quite long and loose and it had lowered due to the shaking of the Benchy superfast print, and now it was getting caught on the left part of the gantry, so the Y axis couldn’t step back enough to reach the Y endstop sensor:

The solution, banally, is a zip tie (not even tight) to raise the cable a little bit:

No more problems.

Sovol has been informed, maybe they’ll add them at the factory, anyhow, I suggest you to do it.

Cheers.

Mine had some black klips provided with the tool kit and some black cable ties. I fitted them before running the first print. Just followed the procedure I did for the SV08. However, the installation manual seems to have omitted the instructions to tie the bowden and CAN cables together !.

Can you post a pic of the clips please…??

[Mindrover]

Sure,

[Fabio]

Mine had them too (quantity 3 actually), but it wasn’t clear what they were for, thanks for sparking the idea. This is my first Sovol printer (and 2nd printer, I had a CEL Robox that only gave me problems and frustration).

Yes, it seems they serve or can serve this scope, although honestly they don’t look very good:

I think I’ll use the zip ties.

[Mindrover]

They are designed to release if something gets caught, which is a good idea. If something gets caught with the zip ties then it will rip everything apart. I recommend using the clips. I’ve had them on my SV08 for months and had no issues.

I should be OK now:

Talking about manual that says or doesn’t say things, mine said there should be a “isolation column” for the filament sensor, but I found none in the package.

Does anybody have a STL file for that? Or the measures, so I design one with OpenSCAD?

Cheers.

[Mindrover]

As far as I know, the “Isolation Column” is just a swivel that was replaced with a simple washer between the filament sensor and the mounting point to allot the filament sensor to Swivel. I’ve not seen nor used the “Isolation Column” the refer to in the manual. (I think this was just an oversight in the manual. I’ve personally move the spool holder to the side and re-mounted the filament sensor. Aurora Tech provide the free stls for the project..

Sure,

Thanks, it was what I thought they were…but mine didn’t come with them.

EDIT: Found them, I came across them today in a box. I installed just one.

I don’t use the reverse Bowden tube. I feed filament straight down through the open top and directly into the extruder so I don’t have a PTFE tube to support the CAN bus cable but my cable isn’t flopping. This might have to do with the curl in the cable (how near or far it was to the center of the cable spool) and whether any twist was introduced when the cable is installed. The CAN bus cable on my Zero presses up against the top back extrusion and isn’t close to getting caught behind the gantry when Y homing, but thanks for this thread to warn people for whom it might be a problem.
