OverLord Pro with Klipper ??
Matias.Gamba 2025-07-14 23:35:13 901 Views2 Replies Hello everyone. I have an Overlord Pro printer, I wanted to know if there is any possibility of using it with klipper. I was able to change the firmware of the controller board to connect it to a host with klipper, but I couldn't decipher the printer.cfg configuration, does anyone know, were they able to do it or can they give me a hand?
From community-contributed configs (e.g. on Thingiverse forums), here's what should go in your printer.cfg:
[stepper_x]
rotation_distance: 40
homing_speed: 50
position_endstop: 297.05
arm_length: 333.0
[extruder]
microsteps: 16
rotation_distance: 33.5
[heater bed]
sensor_type: EPCOS 100K B57560G104F
[nozzle]
sensor_type: EPCOS 100K B57560G104F
[printer]
max_velocity: 300
max_accel: 3000
These values were pulled directly from threads where users reported success running Overlord Pro as a Klipper Delta.
ahsrab.rifat Thanks, I have that information, but my problem right now is pin routing. I can't get it quite clear. There are schematics of the board and everything, but I can't get the pins to be routed correctly using Klipper. For example, I can't get the limit switches to work.
The temperature sensors are giving me erratic values. I haven't been able to decode them yet. It's probably all due to the same pin routing issue. I'm adding my printer.cfg so you can see what I have so far.
