Cube3 running with e3DV6 hotend!

And a video, no endstops yet:

If you would go the TRinamic route, you could avoid having to add endstops.....

But AMAZING JOB! Congratz. The sound of the raising bed is even alien! haha

Thanks a lot! ^_^ Well, sensorless would be great, but TMC2130 is not yet supported by smoothieware, as far as I know...
Could be my future upgrade!

Before you convince yourself you need sensors... have you confirmed that it is actually a belt-jump happening for homing the Cube 3?
I suspect it just hits the torque limits of the motor and what you are hearing is the motor, not a jumping belt.
Just a thought.

Could be, I just feel safer with sensors. A friend of mine is printing the endstop mounting brackets for me, so hopefully today I'll do the first proper homing! ^_^

You are having way to much fun, Kiza! :cool:

In fact, yes, I am ^_^

Z-endstop still needs some work though. Does not fit when transparent extruder cover is installed.

By the way, does anybody know, what are the settings for movement/extrusion? Steps per mm in Cube 3 firmware.

The bearing is 10mm OD... so (Pi*10)/(step angle*360) minus the allowance for filament crush in the driver "gear" since it represents a slightly smaller OD. This could be significant. So you could base the diameter on as little 9.5mm OD.

New Z endstop, corrected. Everything fits perfectly now!

What, no colorful heat-shrink on the solder terminals? :p

Maybe turn the y-axis switch 90*CCW (tray switch)? With wires, that may just be cleaner.
From an ME point of view, we like to let the switch signal but not interfere.
However, you are in a tight spot on both X and Z.
And you have hard stops.

oh, and maybe connect x and z to a single plate so you don't need to disturb the rail screw.
