I recently got my first Sovol and after putting it together and going through startup (which seemed odd - more on that later), I went to print a temp tower. It failed - lots of attempts and lots of fails later (clean the bed, make the brim 10 instead of 5 mm, heat the bed to 70 instead of 60) I did a factory reset.
I recorded it - you can see it here:
Part 1:
You can see in part 1 it seems fine until around 7:35. Again, I’m new to Sovol but it seems be homing at this point correctly in the center, then, at 7:40, it seems like it wants to go to 0,0 but it doesn’t move all the way to the left like I think its supposed to.
From there - at 7:50, it thinks it goes home again, but you can see, it is far from where I think it’s supposed to be.
The rest of the process continually grinds to the right, I’m assuming because the center point at 7:55 is so far off.
I think in part 2 you can see when the process finishes, it again (i’m assuming) tries to go to 0,0 but doesn’t make it, so when I print the cable clip off the usb you can see how far off it bed levels and tries to print.
What is going on here? I’m not even to a slicer, or an actual print!?!
Please excuse my poor English. I don’t understand the error descriptions at the moment. I’m probably completely on the wrong track. Its the origin in the slicer set to the center? The printer’s origin is located at the front left.
This is a brand new printer. When it’s first turned on it prompts for an initial start self-check. Mine seems to be failing at this basic step.
Since I’m not familiar with Sovol printers, maybe the self-check is supposed to be doing what its doing but I don’t think so. I’m really just looking for someone to say, “yeah that’s normal for first start” or “no, something’s not right there".
I’m not even to slicer stage yet, I’m really just asking if this self-check seems like it’s functioning properly.
It’s been a little over a year since I put the printer into operation and ran the self-test. Since I can’t see anything in the video, it’s difficult for me to answer the question. The printer simply performs all the tests listed in the menu. This is standard practice for modern printers. Compared to older printers, some tests can be a bit confusing if you’re not familiar with them. InputShaper tests for resonances. The humming is normal. Measuring the print bed with the load cell on the nozzle is also slightly different than with a BL-Touch. If the value is somewhat out of range, the nozzle will scan individual points multiple times. You should simply let it run completely and trust that the firmware is doing it correctly. Any intervention will only distort the result.
At this point - 7:55 - the printer is supposed to have homed to center (it thinks it went to x:150,y:150 - but you can see from this screenshot, it’s far to the right, more like x:250,y:150).
Because it thinks it’s at 150:150, it proceeds from there and tries to step 150 to the right, but of course it’s almost at the right edge already so just grinds against the right side.
Here’s a better quality video with better lighting.
In this one, it looks fine till around 6:10 - seems to be where it wants to be around x:150,y:150, then it looks like it wants to go to x:0,y:0 but it doesn’t make the full X distance, and from there it’s off. At 6:32 I think it thinks it’s in the center again (x:150,y:150), but it’s definitely not.
Yes, z2 on the bottom right, z1 on bottom left and my board looks like what you posted.
Also, yes, after ramming itself into the right side enough times, it starts going left and ends up “correct”. It was good advice to trust the process and give it a whirl so I:
Loaded up Orca (including importing sovol’s profiles from github into orca slicer), I loaded a test print, .4 nozzle, .20 layer line default profile, no changes to any settings, and I’ve included the result. Aside from the terrible first layer (probably just a filiment tuning issue - I chose “generic PLA), you can see where after the first layer the whole print shifts and the next layer squares are off.
I have no idea how you know which point it’s currently moving to during the test. In my opinion, it’s aligning the X-axis with the print bed and correcting the two Z-axis lead screws.
My last thought would be to check the menu for a firmware update. Often the test is performed before the printer detects that an update is available. Afterward, another test is necessary anyway.
Orca has made significant progress and adopted Sovol’s profiles. Generic PLA noticeably slows the printer down. Use Sovol SV06 ACE Plus PLA. This will utilize the printer’s full capabilities.
