  • Look on github for Rappetor’s SV08 mainline repository. You’ll need a new mmc or sd card (both are ok) and a “five bucks” STLink programmer, but then it is quite easy to put mainline klipper on your sv08. The mainboard is a cb1 clone with the “main” ST microcontroller for driving the steppers on the same board (for cost reduction, probably)

    That’s the prerequisite for using a probe. like a btt eddy on a SV08, for example.

    Other than the SV08 has a few issues like super noisy board fan which can be very easily be taken care of. (Funnily software control of the fan is possible, but just not done in the default firmware)

    My mods are mainline klipper, btt eddy, new (printed) extruder shroud with better airflow, a microswiss hotend and a second camera (USB webcam for second viewing angle and better resolution).

    Out of the box the SV08 has a bit of problems keeping a consistent Z offset due to missing temperature calibration for the probe. More reliable solutions (ported from voron) like klicky are available. I chose eddy - but haven’t perfectly tuned it in, either. I’ll try the eddy-ng firmware (github) next week.




  • They might just try a cold pull or two before changing the nozzle. (Depening on the printer. On my Ender 3 Nozzle swaps were a no brainer - 2 minutes, on my current SV08 they are 15 min of work and 45 min of soaking the old nozzle in Isopropanol to get the thermistor out without ripping the cables)



  • I had inconsistencies in my print on an Ender 3pro with sprite, no kind of manual or ABL level fixed it.

    It turned out one of the eccentric v nuts at my gantry was too tight, so it didn’t run smoothly - the right side of the gantry lagging to the left. (Ender 3pro has only one z screw)

    So check for mechanical problems, lubrication of the z rod etc.

    For the V wheels - they need to be adjusted so thight that you can just turn them manually with one finger then one ministep thighter.
