@blacksmithforlife 🇺🇸 @TheTik if you happened to know: the only spare part I have on hand is this cheap knockoff stepper I got from the assistance team of another brand for the Z axis of another (cheap) printer it doesn’t have any labels, it’s a bit smaller and the shaft is like 1/2mm shorter would it be a terrible idea to try it out?

(straight) Rear leadscew is wobbling

At this point I might order again from RR, hoping it won’t take like a month like last time (even though I just ordered 1kg of filament and a bunch of spares)

Italy, I was looking for European sites and the only one I found so far is 3DO, which has 10€ of shipping fee anyway, on top of making me pay 10€ more for the motor so like, 35€ total

so I guess it doesn’t count unfortunately, also it might have been damaged during shipping so I really have no alternatives

I tried homing all 3 axes and doing an emergency shutdown before the other 2 leadscrews crashed on the top but it's a huge risk for those lol

speaking of which, it might be a really dumb question but how can I check for the wobble without the leadscrew (and the buildplate of course) installed?

1) if there's any way to fix it manually (even if I don't think so) 2) what's a good place to buy them on aliexpress or european stores? this one specifically is an LDO NEMA17 (42STH48-2504AC), I could even go for a cheaper one on the short term
