Printing
I build a core xy 700x500mm
motors are 3amps nema23 with klipper and octoprint
it is not set completly
in klipper I set an delay for drivers like 3usec to eliminate posibility loosing steps
for the first prints is looking good
the problem is this layers are not alingned verticaly
one of each belt have around 5 metrs and are very long in my opinion
I left it little bit loose , I tight it , the f

I wired straight from pin fan arduino and is working
I'm not sure if must use that resistor 10k
now is working without that resistor but I would like to know why some people are use it
for different materials i use a dimmer to control power intensity and also still in testing trying to print images
so i have variable intensity 0 to 255
also variable power true laser from dimmer
maybe somebody k

I just bought this laser from aliexpress
is a 2 W laser
I connected to my radds on fan pin 2 and used with commands M106 P1 Sxxx on, and M107 P1 off
is working
but i want to try TTL
controller for this board is
the problem is I use RADDS with arduino due and pinout are on 3.3 v
I try to figure out how to use it with my board true TTL
I am not sure but i try to draw a small schematic us

I bought this toy over ebay and I was surprised when I saw there is no info on internet about motors
This lens got 2 motors steppers , mini, and when I measured there are 2 coils 39.3 ohms
means are normal steeper motor
maybe somebody have a clue how can I drive this motors, which drivers i need to be used
thank you

General
I come back with new info
I think my arduino due is not original
On radds 1.6 I found an circuit closer to display pinout HCT365 2L5E401, i think is an TTL logic for display but i don't know how to test it if is broken or not
I measure circuits for termistors and look ok
if I try to heat nozzle or bed , they are working
temperature nozzle is showing, temp bed remain the same 4 degree

Controllers
I just buy few days ago RADDS 1.6 arduino due RADDS lcd 20x4 char
core xy
x, y z, are controlled by 2DM542 with nema 23 , so I took from board only EN , STEP, DIR and GND, increasing high_delay 5, and double_step_delay 2
extruder is controlled by A4988 , is an 0,9 degree from E3D
I try to put repetier 1.0.2 but without success
Problems:
1. After few rewrite firmware LCD begin to show me only

Controllers
I write again about this situation because I don't find a real solution for it
I build a core xy and i intend to use repetier firmware on my ramps 1.4
my problem is after uploading the firmware my printer is not moving right
my printer is core xy full discount display ramps 1.4
if i try moving on x +, my printer go on x
if i try moving on x -, my printer not moving
if i try moving on y +, my p

Repetier
I got 4 motors nema 17 LDO-42STH60-2004AC and I like to know if there any chance to drive it with a single 2DM542 Microstep Stepper Motor Driver
I plan to put a motor in any corner of surface to lift it.
motors are 2 ohm on my multi meter
I don't find on internet if is ok to put motors serial or paralel connection or is something more mast can do to make-it working
thank you
