During printing model( model in attachment and also the time lapse until failure) at some point X and Y offset instantly got so bad (diagonal around 100mm) that printer head started to repeatedly hitting printer frame very hard. I would like to know if I’m only one with such failure and if you aware of why this could happened. Alongside with this topic I send email to Sovol.

I can’t see anything from the timelapse.

Timelapse is only to indicate that failure happened almost instantly after last recorded layer. I did instantly ran to abort print.

On a core XY “lost counts” on either the A or B motor will result in a diagonal shift.
The root cause is the nozzle colliding with the print. The question is was the collision severe enough to actually stall the motor or did something “slip”.
Check the grub screws in the belt sprockets on both motors.
Double check belt tension.
If both are good then you need to examine the model and print process to minimize curl/warping of the part. Z hop might help but is slows the printing process.

That’s may be it because first noise during failure was different. Maybe it was a collision.
I’m pretty new to VORON like 3DPrinters could you indicate on this images which screws I need to check:
I did check check belt tension twice even before first print. I used this tutorial [SV08 AB axis belt replacement and adjustment tutorial | Sovol 3D Printer Wiki](https://wiki.sovol3d.com/en/SV08-AB-axis-belt-replacement-and-adjustment-tutorial) and yes out of the box tension was off by around 70 Hz. I will look into project in the mean time.

Looking from the back…
There are 2 grub screws in each belt drive sprocket. Note the belts are not in the CAD model.
Same view on the SV08 (not max) shows you’ll have to work around the belt.
There are 2 screws in each sprocket.
When you tightened your belts did you put the X rail the same distance in mm as in the video or at the center point? If you had a longer span than the video and tuned to the same frequency as the shorter span your belts are too tight an could damage the motors and belt rollers.
@sovol3d where is the belt tension info for the Max?

as in tutorial, 150 mm from front idler center.

Perfect.
I didn’t re-watch the video and couldn’t remember if they specified a distance or to “center the gantry”.

thanks for your insight! when you say check the grub screws, what are you looking for in terms of just that they’re not protruding? and they tighten with a normal wrench? I’m having mechanical problems on prints and it was recommended I look at these grub screws - how would I do that without completely loosening the belts? or it’s assumed I would do that first? thank you for your time

> Hi everyone, My Sovol Zero recently started printing very inconsistently. I’m getting clear under-extrusion — layers are thin, gaps appear, and prints fail. Here’s what I’ve already tried: different filaments nozzle replacement calibration and cleaning checking the filament path The problem remains. After opening the extruder, I noticed that the drive gear looks worn and slightly damaged. It seems to be slipping on the filament. Has anyone experienced this on the Sovol Zero? I…
The MAX & The ZERO use the same toolhead.
