First printer in 2017. Kit is ok, but configuration has some undocumented issue (but forums has answer). - discoeasy 200

• 3d printer tips from hackaday

Ecran Rep rap

• ajouter un écran RepRap FullGraphic

enlever les detrompeurs des nappes coté ecrans et les brancher a l’envers en gardant la correspondance exp1 / exp2. (les nappes dagoma ont juste les detrompeurs dans l’autre sens)

• boitier alternatif sur thingberse

• upload du firwmare supportant l’ecran cd dagoma

• Flash a partir des sources marlin

  • recuperer l’arduino IDE
  • ouvrir le fichier marlin.ino
  • choisir type de carte “Arduino Mega or Mega 2560”
  • idem pour CPU type

• l’ecran a besoin d’une librairie additionnelle U8glib

  • ajouter la lib depuis l’ide Sketch/include libraries/manage libraries puis search U8glib et install

    • compile + upload

tips for Dagoma DiscoEasy200

firmware

Klipper

old disco easy note below

• enable display lcd => ok push => ok up => KO down => KO

choose entry

# "RepRapDiscount 128x64 Full Graphic Smart Controller" type displays

• Verify temperature

temperature reading seems ok (room temperature)

Heater Fan

Verify that fan are on when temp is above than 50c => ok

Add any number of aditional fans for cooling stepsticks or the coldend by adding Sections to your config.cfg Theyll switch on once your hotend is set to 50c and switch of once its cooled below 50c.

temperature fan

• Verify M112

M112 => cause disconnect

• Verify heaters

extruder Temp control => heat / stabilized / off

Calibrate PID settings

Check first that fans are on at 50°

PID_CALIBRATE HEATER=extruder TARGET=170

Recv: // PID parameters: pid_Kp=40.060 pid_Ki=3.762 pid_Kd=106.660

Verify stepper motor enable pin

enable_pin ok, X/Y/Z free move

disable motors (M84)

• Verify endstops

Send: QUERY_ENDSTOPS (M119) Recv: x:open y:TRIGGERED z:TRIGGERED

Discoeasy default build has x- trigger on y axis

As it is quite easy to rectify that => I have chanded it as shown here below.

From now it is obligatory to remap or use alternative marlin

After Remap

Check individual axis trigger (M119):

• xAxis => ok (endstop_pin: ^ar3)
• yAxis => ok (endstop_pin: ^ar15)

• zAxis => ok (endstop_pin: ^!ar18)

• Verify stepper motors

Check individual axis stepper motor:

• STEPPER_BUZZ STEPPER=stepper_x => ok
• STEPPER_BUZZ STEPPER=stepper_y => ok
• STEPPER_BUZZ STEPPER=stepper_z => ok

• STEPPER_BUZZ STEPPER=extruder ( with no filament) => ok

• Homing mind the power switch
  • G28 X0 => ok
  • G28 Y0 => ok
  • G28 Z0 => ok
• Compute step_distance on each axis
• X step_distance: .0125
• Y step_distance: .0125

• Z step_distance: .0004

• Verify extruder motor using octoprint control

-Calibrate extruder motor apply ratio of / and modify step_distance accordingly.

Configure Homing seq - (also discussion)

G28 (full homing) that mimic previous behavior
