just tried the "fussy" outer shell option on my ender5+, i like it and it hardly slows a print at all . i never knew it was there until now
thanks for that, its a nice way to disguise the layers. i...
Ioannis, I owe a you a beer or 3 :) My voltage reg was underrated to that required 3.5A. I got away with it for the 2W modules, but not these. I never would've thought of that being the culprit for...
the motherboards are just arduino mega2650 dressed up a bit with a nice cnc coat on, you can recover them using another arduino as a icsp programmer.
i used my old mboard as a grbl core xy laser...

I have been thinking for a while, how to put togeter a simple microstepper controller without using a ready made commercial driver.
At the end, I came up with this simple project capable to drive unipolar stepper motor in three different modes
FULL STEP
HALF STEP
MICRO STEP
The Pic micro used in this work is a Pic 16F628 a powerfull small micro with PWM capability. With this MCU plus a 74HC04 and a74HC86 the controller will produce 20 microsteps out of a nominal motor step.
An additional improvement of this controller, is the capability to accept travel commands of 24 Bits, wich gives to the user the possibility to send positioning profile of over 16 millions steps.
Controller accept commands via TTL serial port @ 9600,n,8,1 and return an (Ack) once the positioning profile has been completed.

Also attached is a simple stepper controller example called Stepper_MK2.zip
