Servo Calibration?

Discussion in 'Community Support' started by Christian Dannesboe, Jan 28, 2015.

  1. I struggle to get my printer working, and currently have given up on the servo.

    After a firmware update to 0.15.2 the servo lowers the rollers until they hit the bottom plate. Servo starts the loud noise as it tries to force the rollers even further.

    Maybe I did something wrong during assembly?

    The assembly instructions tells you to connect the servo to AOUT1 (page 154, instruction 31), but the trouble shooting guide says it is connected to AOUT2 (

    The trouble-shooting guide further tells you to calibrate the servo. Not a bad idea?

    There is even a guide: (

    Sadly, this option has been removed from the software??

    What to do?

    Will the printer do prints without the rollers?

    Hey Christian,

    Thanks for letting us know about the inconsistency between the instructions and troubleshooting, i've fixed it. We've temporary taken the roller feature out of the software while we improve it. We're aiming to have a new version of the software out by the end of the week that fixes a bunch of bugs and has better support of the roller.

    Your Argentum will definitely be able to work without the roller. It's only function is to dry your print after each layer. You can just dry it by hand with a paper towel as described in your first print.

    Believe me were working crazy hard on fixing our software issues at the moment.

    In the mean time you should just disconnect the servo cable from the motherboard and manually push the roller into the up position. That will keep it out of the way of printing for the moment.
