Hello all. So I’ve had my Zero for a little over a month now and it’s certainly very fast but the print quality has left a lot to be desired. In the attached photo, I printed the same container on the Zero (in white) and on a Prusa MK4S (in black). You can see the clear ringing on the print from the…

The video made me have an existential doubt: is the Zero really CoreXY or is it H-Bot? By the way, for those who don’t know the difference, I’m linking this video, here it’s very emphasized anyway: https://youtu.be/-HLCfR7mnVA Clearly, the linear guides of the Zero are very rigid, yet it seems t…

Core XY. Both belts run clear across the back. The rollers are stacked on the Z axis which they couldn’t show in the simple 2D animation. [image]

There is an STL on the USB drive for the Zero called “Hot bed calibration block”. They tell me there will be a video for how to use this sometime in the future. [666]

Yeah I was wondering how to use that file but couldn’t find any info on Sovol’s wiki about how to use it.

Updated my OP with new info for anyone interested.

@pr1nter - What filament is that and what temperature are you using to print it? Have you followed the recommendation of the input shaper when setting the maximum acceleration value? I suspect it will be less than 10k for everyone, that 40k is just marketing and will result in ringing calibrated …

Thanks for the reply Vergo. So this is my first actual Klipper machine so just assume I know nothing about how to calibrate stuff in Klipper. Not new to 3D printing as I’ve owned Prusa’s and Bambu’s for a number of years, but haven’t had a Voron style printer with straight up Klipper before. AFAIK, …

Point of note: If you have done flow rate calibration leave the E rotation distance alone or you’ll have to redo the flow rate. They are intrinsically the same thing. Example: Say your rotation distance is 10.00mm and your flow rate is .98. The slicer sends a move that calls for 1.00 mm of fila…

Another update. I finally heard back from Sovol CS the other day and they recommended checking the belt tension to make sure it’s at 110hz for both the X and Y axis. One of my belts (left side) was way loose at around 70-75hz so that was likely a contributing factor to my print quality issues. Tight…

I’ve been through a similar process and it took me down a rabbit hole of issues. I tried all the tuning processes I’ve used on my Vorons and SV08. I also went over the physical build with a fine tooth comb and found a plethora of loose screws and poorly adjusted parts, not least of which was the pi…

See Z-Offset is not saved - #14 by Liberty4Ever for some IS shaper discussion. Yes it is off topic but sometimes we get distracted.
