Hello. Looking for tips on leveling the SV04.
I notice the instructions mention heated bed in leveling guide. I don’t remember this on the Ender3 Max I used before. So, now I am heating the bed to 60°C before leveling. Do you? These are the steps I am taking to level:
Adjust right extruder all the way up. Move bed adjusting screws so bed is lowest setting and rotating same knobs one turn raising bed slightly. I then go to Settings->Leveling and let machine auto-home. I then select Auto Z-align and let this complete. I then select AUX leveling and repeatedly adjust all four corners until a slight drag on paper with left extruder at all coners. After this is done without further needed adjustements, I start adjusting the right extruder and have placed this extruder at a corner. After adjusting the right extruder so there is a slight drag on the paper, I tighten the four small side screws on this right extruder (I assume these get tightened, but have not actually read this in any guide), but I notice the paper doesn’t drag as much after tightening the right side screws on the right extruder. !
So I loosen those screws again and readjust, but same thing after tightening screws. I adjust so the paper is dragging heavy and after tightening the screws I feel the right extruder is close to the same drag as the left extruder.
I then select the House icon to auto-home. I then adjust the Z axis in the center of the bed until paper drags and select Save. I select the House icon and can usually confirm proper height of the left extruder with paper drag. I then select Measuring and let the 16 point bed detection. I then select Save (multiple times). I would think I should be good, but…
Sometimes, Auto Homing doesn’t leave the left extruder as close to the bed as I left it before. It is usually 0.05mm high. Not too bad, but it is as if there is lead screw backlash and it’s not compensated. I don’t find any notable backlash, but it kind of explains the results I am finding.
I then run the dual extruder calibration test and notice that the right extruder is running too high and have issues with filament sticking to the bed. Now, the left extruder seems to be running at the correct height, but it is running into somewhat loose filament from the right extruder, but is successful for the most part.
What am I missing - Especially with that right extruder. Should I leave those four side screws slightly loose after height adjustment? Doesn’t seem right.
Also, on the calibration test, the left extruder’s filament is a bear to get off of the flex plate. I am used to the glass plate on the Ender3 where the heated bed really grips the extruded object, so I let the bed cool and the object comes right off. On the Sovol, I couldn’t get much of the calibration filament off when cool. I heated the bed to 85°C and let it sit for a few minutes and could finally scrap off the job. I realize normal jobs will usually be taller, so there is more to grab, but is the flex plate designed so the object should be taken off the heated plate asap??
Sorry so long. Thanks for any tips!!
