Creality 3D® 42-34 Motor for Ender-3 Series Ender-3 V2 3D Printer
A part of the review has been auto-translated.
Original Creality boxed products. Fixed my problem! I switched of my printers without disconnected the Raspberry Pis that run OctoPrint and it killed the Z-axis motors (because 5V DC was being back fed to them all night from the USB - they need pulses not continuous current - note, I had replaced the mainboards with BTT SKR Mini E3 V2.0, however it is apparently a known issue in the community). These were the only ones I could find that precisely matched the original specification - round not D-shaped axel of the correct length with correct electrical parameters - plenty of others are available but you will need to know a lot more to be able to get them up and running - therefore these were effectively plug and play. With my setup the Z-axis drops when power is removed or the print is cancelled (definitely with default OctoPrint g-code for Cancel), so be careful not to scratch your bed (I made sure I was holding the Z screw to stop this, and while clearing the bed, then rotating it to raise the print head before running a home move again so that the motor reengages before letting go) - learn how to modify firmware and end/cancel g-code to mitigate this.
It is working but i got a motor with a D shaped shaft. Thankfully customer service resolved the issue.
Great quality, delivered ahead of schedule. I would like to have had the option to buy these steppers with leads to suit dual 'Z' screws.
