Thanks, I think I already found a way to achieve this here. I'll do some more research, but I'm pretty sure I'll implement this.

@phaedrux Really nice printer you have there. Why did you choose these "wheels" instead of smooth rods and bushings?

Thanks for all the replies, I'll add these to my considerations.

While thinking about the problem of asyncronised z axis stepper, I was wondering if you could set two additional endstops for both stepper motors at their max z position. Then you would have to program a macro that would go to the max z position and stop each stepper motor individually as soon as they hit "their" endstop. You could run this every time you power on your printer to syncronise minor differences and therefore could use two stepper without the risk of them bein asyncronised.

I was actually planing on using an ac bed heater with a ssr. What other benefits will I be having with 24v?

So I'm guessing the 65 Ncm stepper motors will have enough torque? Also with a single stepper motor for z?

Hey everybody,

so I'm in the process of building a hypercube evolution and have a few questions that I hope someone here can answer. But first things first, I'll build the 300 x 300 x 300 build volume variant with a duet wifi as a contoller and a 12v power supply. I was searching for stepper motors and quickly realized, that I had no clue which ones to choose, since this will be my first build from scratch (before I only modified my existing printer). After reading up on the subject, I'm leaning torwards buying these motors. Will they have enough torque (65 Ncm) for my printer? The weight of the stepper motors is not an issue, since they will be mounted to the frame and not moving.

Bonus question: I'll build my printer with 2 z screws. While googling I found several hypercubes with 2 z screws but just one motor, that drives these screws with a belt, like this for example. Would one stepper motor like this be enough for the aluminium bed frame and a 300 x 300 x 6 mm aluminium sheet? Would there be other downsides to this approach?

Thanks for the help!

You are right, I was under the impression you were asking for a way, other than G30. Thanks for the clarification, this post can be deleted.

Hey everybody,

I was working on my G-Code the other day and I was wondering if there is a way to to use a second, slower pass on Z homing with the Bl-Touch? I tried G1 S1 Z-300 F100 but my printer is ignoring these z homing commands and will only z home with G30.

So is it possible to something like:

G1 S1 Z-400 F1800 ; move Z down stopping at the endstop
G1 S2 Z1 F3000 ; go back a mm
G1 S1 Z-400 F100 ; move slowly to Z axis endstop once more (second pass)

... but with G30, or reduce the speed of G30 homing in general?

Thanks a lot!

Would it also be possible to get some 5 v rgb leds connect each colour to let's say heater 3-5 on the expansion header and gnd to gnd obiously and controll the colour via M42 commands? Would the heater pins supply enough amps?

Quick follow-up question.

I stumbled upon some quite neat fans from sunon with "Vapo" (magnetic) bearings. They are advertised as being quieter than the human hearing capacity and more durable than ball bearings. Since they are about 8 bucks each I´m a bit hesitant to buy them straight away. Does anybody have experience with these fans? https://www.conrad.at/de/axialluefter-12-vdc-9-mh-l-x-b-x-h-40-x-40-x-10-mm-sunon-ha40101v4-0000-999-184264.html (sorry, it´s in german)

Thanks you David and deckingman for the quick reply!

@deckingman special thanks to you, the site provided is great for comparing different brands

So I recently ordered my duet wifi and now I´m planning to exchange a few parts on my printer while I upgrade my board to the duet as well. Especially my hotend mount and part cooling fan were bothering me quite a lot. I´m planning to use either 3 40 mm fans (two for parts and one for hotend) or one 30 mm and 2 40 mm ones.
The problem now is, that I got pretty lost searching for the correct fans. As far as I´ve seen the board only has two connectors for the fan but unfortunately most 40 mm fans have 3 wires. How would I connect these to the board nd would I still be able to adjuste the fan speed?

Furthermore, do you have any rcommendations on 30 and 40 mm fans?

Thanks!
