Replicator 1 Dual - Tool1 manual extrude/retract causes carriage to move

[leeph]

Issue description & environment

Running Octoprint 1.3.8 on a Debian9 (x64) HP desktop, GPX version 2.6.2

Printer is a Qidi Tech 1 (2017 model) using "Replicator 1 - dual extruder" machine profile, reprap GCode flavour.

Everything works great in terms of uploading GCode generated by 3rd party slicers, I want to clarify that before I start. Using Octoprint's built-in manual extrude/retract buttons works fine when selecting Tool0 (right-hand nozzle as you look at the machine) however using the buttons having selected Tool1 results in no extrusion or retraction, but instead the carriage moves slowly towards 'home' in the X-axis.

Steps to reproduce the issue

1. Heat nozzle T1 to extrusion temperature
2. Switch to the 'Control' page, Select Tool, Tool 1
3. Enter 5 or 10mm (or whatever) length in mm to extrude or retract
4. Hit the 'Extrude' or 'Retract' buttons - the result is the same. No extrusion or retraction takes
   place, but the carriage moves slowly right in the X-axis and then stops after a short while.

What's the expected result?

• Extruder 'Tool 1' (left-hand nozzle) should extrude or retract the specified amount of filament when the appropriate button is pressed, having selected 'Tool 1' to interact with.

What's the actual result?

• No extrusion or retraction occurs, but instead the carriage moves slowly towards 'home' in the X-axis.

Additional details / screenshot

I can provide a video of the resulting behaviour if it would be of any use. I can also provide my GPX.ini if necessary, however it's basically default as per the included Replicator 1 Dual machine profile.

This is normal.  You're seeing the tool change happen first but because it is not being done correctly for makerbot-style firmware you first get a very, very slow motion to effective the tool change.  Tool change is a displacement in x by the tool offset.On Apr 16, 2018 12:54 AM, leeph <notifications@github.com> wrote:Issue description & environment Running Octoprint 1.3.8 on a Debian9 (x64) HP desktop, GPX version 2.6.2 Printer is a Qidi Tech 1 (2017 model) using "Replicator 1 - dual extruder", reprap GCode flavour.
