Anyone have any data for the stepper motors? I can’t find anything based on the part numbers printed on them. I have my SV06 ACE printing pretty well, but the motors make a lot of whine compared to my other printers, and the VFAs are bad. I sent an email to Sovol, but I don’t expect to hear back for a while.
I run my outer walls at 55 mm/s, which I’ve found is as fast as I can go with PETG to keep it glossy (on my other printers, haven’t really experimented with speed on this one). When matte, the surface shows scratches, and I’d guess gives up some strength.
First thing that comes to mind are the stepper drivers. Do these have some sort of Trinamic quiet drivers ? Can they be upgraded ?
They are TMC2209 drivers, but no tuning values were set in the Klipper config. I ended up using GitHub - MRX8024/chopper-resonance-tuner: Registers calibration script for TMC drivers, which did cut down the noise a good bit. I was still getting bad VFAs at 2mm, especially on Y. I replaced the X idler with a toothed one, which seemed to help X. I swapped out the Y idler and Y motor pulley, but those didn’t help. I probably should try the Y belt next.
