Thoughts after eight prints into #3dPrinting with my #SV08
-
I honestly think many of the complaints on the printer are due to the assembly instructions: it would be remarkably easy to put this printer together out of square given the instructions. Indeed, several YouTuber have described forcing the pieces together: I bet it they are all dealing with parallelograms. Assembly with a square and more hand holding would solve this problem IMHO.

The filament load, though, is a design flaw. There is something in the upper part of the extruder that catches filament in a way that you can’t see. I’ve been printing for years and I still fiddle with it. My current strategy is to use the filament load macro and push from the runout sensor (= TPU is probably going to suck).

The noise is pretty bad. My wife describes the high speed moves as sounding like an alarm going off and the printer is on a different floor and behind a door. Mainboard fan is constant and high pitched: it’s far louder than my furnace. I think this can be fixed easily though with aftermarket fans.
Software seems okay, although I’m a little miffed that it lacks on-board programmers for the microcontrollers (updates will be painful). Otherwise, I would prefer fluidd but I’ll live.

@linux_mclinuxface I don't understand printers still being loud except for fans. Stepper motors with modern drivers are really quiet, even in high performance mode, and usually quieter at high speeds than low. You like have to actively screw stuff up to make the motion system loud.

@dalias I have a theory about this printer.
SOVOL doesn’t do limit switches. They do sensorless homing, which requires higher current to the steppers so they stall out.
During high speed moves they are pushing the limits of the current handling of the drivers and/or motors and this is causing resonance (or some sort of other side effect) whine.

@linux_mclinuxface Aiaahhh that is too bad, as a Tinnitus patient myself. I think I won't be able to come near to that 3D printer.

@melroy I wouldn’t suggest it unless you swap out quieter fans.

@linux_mclinuxface @dalias So, would you recommend this printer?
I am in the market for an upgrade to my trusty old modified cr10. This has been the more affordable choice, and i'd like to not walk into a vendor lock with bambu labs. -

@linux_mclinuxface @dalias You actually want lower current during sensorless homing to avoid going "bang". Tuning for sensorless homing is turning current down as low as you can still reliably home. And then you set current differently for running than for homing. (I've set this up with both Marlin and Klipper.)
I think it's just too fast for the quiet stepper driver modes.

@newhinton @dalias The jury is still out for me. I do like it thus far, but we'll see in a few weeks how I feel.
So far, I would not recommend it for beginners, but it may be a good printer for the right person.
