Voron 2.4 3MB6 §EB config issues.
-
@Titus-A-Duxass because we're setting x16 rather than x64, so the values need to be dividing by 4 as we're using 4 times less microsteps

@jay_s_uk Okay, I think I understand. I need to do a bit of reading about microsteps.

@jay_s_uk My config.g now looks like this.

@Titus-A-Duxass you need to change the X and Y steps too from 320 to 80
-
@jay_s_uk Done.
-
@Titus-A-Duxass have a go at homing and see how that performs
-
Perfekt!!
I positioned it at approx. 150 for all three axes and all homed with out an issue. -
@Titus-A-Duxass great news. if you need anything else just ask

@jay_s_uk
Once again thank you for your invaluable assistance.
I owe a beer/tea/coffeee. -
I'm back, just a quick question.
After I have homed all, all motors are powered (you can just hear them buzzing) is this normal? -
@Titus-A-Duxass yes, you can get that when they're in spreadcycle.
if its something you want to reduce, then you could switch them over to stealthchop.
you either want to switch over at very low speeds or always run them in stealthchop.
you would do this by addingD3 VXto each M569 line, with X being something like 4000 for low speed switch over or 1 for always stealthchop.
If you can live with the sound, stick to spreadcycle. -
@jay_s_uk
Thanks, I leave it as is for the moment until I become more confident.
This thing flies, just gone from X200 Y0 to X20 Y250 in less than a second - scary fast.
