Hi everyone,
Thanks for reading my topic.
A while ago i had my prusa i3 that was wobbly and cheap all around. So i decided to upgrade it to a wooden core XY printer based on this design :
I have some issues with the firmware. I can't home certain axis based on the location of the endstops :
#define X_HOME_DIR 1
#define Y_HOME_DIR -1
#define Z_HOME_DIR 1
Here i can't home X and Z, they juste

Yes it seems pretty stable, i'm using E3D filament printing at 0.2 mm layer height and with a 0,4 nozzle

Ok thank you other than that everything was accurate.
But from 97,6 to 101,9 is it thath big of a difference ? could that be my problem ?

I have a Bowden extruder, how can i calculate the e steps for that since i dont have a gear reduction ?
e_steps_per_mm = (motor_steps_per_rev * driver_microstep) * (big_gear_teeth / small_gear_teeth) / (hob_effective_diameter * pi)
Do i replace "(big_gear_teeth / small_gear_teeth)" by 1 ?
In that case my steps per unit for the extruder would be 22.22 ... That is very different from what i hat

If a little wobble in a 5mm dia screw causes the frame to flex, then the frame is poorly designed/built, too.
Jeez, it's no wonder these things aren't ready for consumer use. Instead of getting more reliable, they're getting cheaper and harder to operate because you have to worry about this sort of nonsense created by stripping out quality in favor of the cheapest way t

Hi, i'm using M5 thraded rods too and the pitch looks similar to yours, i print ,with 0.2 and tried a multitude of layer heights with no change...
I have no idea for the number of steps per revolution on my stepper motors, how can i tune all that together ?
thank you

Hi thanks for helping me
No movements at all on the extruder carriage, or on the printer itself
Here are my values for the PID :
dflt kp : 35.05
ki : 3.96
kd : 77.52
i have no play on the Z axis
How to tell if my Z motors have enough current ?
I tried moving the carriage up and down and had no tilting of the hotend

Hi everyone !
thank you for reading my post
I have my prusa i3 since december 2014 and i have an annoying problem that i can"t seem to fix ... My layers are uneven (see attached files) kinda like a Z wobble but the pattern goes : one thick layer, one thin layer...
Here's what i tried with no change at all :
-Bought new smooth rods (those from my kit were of the wrong diameter which produced a

Hi,
I recently installed an auto bed leveling probe with a servo on my prusa i3. Everything works fine except that after it does the probing, it doesn't seem to register them. It prints like the probing never happened... which makes the system useless..
Have you guys encountered this problem before ?
Thanks a lot in advance

Bonjour,
j'ai récement installé un auto bed leveling avec un servo moteur sur ma prusa i3. J'ai suivis à la lettre tous les tutoriels que j'ai pu trouvé et pourtant quand je lance une impression, le probing ne change rien ... La machine fait les probes correctement mais ne les prends pas en compte, peu importe l'inclinaison du heatbed .. Du coup je perds tout l’intérêt de mon installation :cry:
