#TINY ZEBRA TATTOO DRIVERS#

'High' speed prints don't look as good as 'Normal' and since i am only interested in the best quality prints, i would only ever use 'Normal'.

How fast can your M200 print compared to a UM2+? This will increase the current, the noise and the ripple current (more EMC radiation).

I just changed the mode of operation on all stepper drivers from «automatically-selected mixed decay» to «mixed decay set to be active 100% of the time». In some application where micro stepping at low speed is necessary, a lack of EMF pulses can cause the current to increase rapidly in the actual stepper winding, -resulting in missed steps cause it will jump two steps instead of one.Īt such low current micro stepping, it can be the stepper motor, the impedance or to long feeders (increased resistance), or to low «stepper voltage» that is «creating» this problem.Ī fix might be to move the stepper drivers closer to the stepper motors. When stepping in this mode, the feedback (EMF) is monitored by the stepper circuit in order to keep the current steady. When this stepper driver is doing micro stepping, this stepping is made with very low current, typically around 0.1 Amp (or 100 mA). I don’t think so, because they use same firmware, same slicer and same stepper driver. Yes it was the same printer that printed the Bency-boat and the Tail of the A-380 that I've now modified.

Well, by sharing this I'm trying to give a little back to the forum and Ultimaker for the veld of information there is open for everyone to see and use for their ideas.
