CTC Bizer / Dual v 7.7 Sailfish printing issues

Printer: CTC Bizer (2560 chip)
Slicer: Cura (latest Version)
Error occured straight AFTER flashing


Everything worked well on stock 7.4 FW
Printing from SD Card with Cura Gcode converted to .x3g works flawless.

What is the problem?

When I click on Print:

  1. extruder / bed is NOT heating
  2. steppers are making a sound (like when printing)
  3. printhead stays in the home corner
  4. printhead is moving very very slow, less than 1mm / s

At some point this problem dissappeared and magically appeared again. ( I didnt really change any thing)

What did you already try to solve it?
I tried to make sure all GPX and ocotPrint settings are correct.
I upgraded my Ocotprint and Plugisn to the latest version.
Tried different Start gcodes and veriefied they are working (sd card print works fine.)

I'm not really sure which Info I need to provide. I will provide everything you need, just tell me :slight_smile:

  • OctoPrint 1.4.0 auf OctoPi 0.12.0
    GPX Plugin : 2.6.2

I only use the right extruder. Yes GPX is installed, maybe I do not have the right settings. In Cura and Octoprint I selected Replicator 1.

The homing on the printer itself works also when print from sd card.

I will try to attach my GPX / Octoprint settings as well.

In octoprint I'm not able to control my printhead not via the buttons nor via the Terminal G Codes. Sometimes it starts making some noise but its not moving correctly / at all.

Can we see your start and end code for cura? Sometimes the problems in there. Also home paramerers on printer. Do you use one or the other extruder only and then switch? What did you define the printer as in octoprint? Make sure there gpx plugin is installed.


Hey thanks fort your reply. Im kind of frustrated. Ive noticed some more Problems. Its NOT Cura, Not the gcode nor the printer, because sd card printing works still fine.

Check the original post, I added some Info there
