Random moves to same location during print

Get Help
1

What is the problem?

When using Octoprint (1.7.3) running OctoPi (0.18.0) on a Pi3B+ (Python 3.7.3), I get random movements to the same locations during the print, where the print-head pauses for 1-2 seconds (oozing out some material) before continuing print. It seems to do this each layer depending on the shape.

What did you already try to solve it?

I ran in SAFE mode.
Then ran normally. Problem occurred again.
Then I disabled plugins some plugins which people had mentioned can cause issues with the print.

If the printer is connected to the computer through USB (not using RPi3+) the prints are do not have this issue.
Only occurs when running OctoPi/Octolapse in normal mode with plugins enabled.

Have you tried running in safe mode?

Yes

Did running in safe mode solve the problem?

Yes

Additional information about your setup

OctoPrint version 1.7.3, OctoPi version 0.18.0, Bukito, Marlin 1.0, Firefox, Win10,

The printer is similar to a Ender 2 (i think), or Prusa mini.
It has a custom Azteeg V2 board (8-bit I believe)
The Marlin software is Version 1.0. I am uncertain if it can even be upgraded to a later version.
At the moment I do not have a copy of the firmware to modify and test.
When printing from the computer instead, this print move does not occur. I'm using Repetier Host V2.2.2 for the computer driven control with a Slic3r for slicing.
Slic3r is used for slicing the files which are then saved and uploaded through Octoprint interface if I print with the RPi3 instead.
I have Cura 4.3 and Prusa-Slicer 2.4.1 but I have not set them up for this printer.

This is an copy of the Terminal log when the move/pause occurs (Normal mode)

Hello @Silent_sound !

It looks you have Octolapse activated.

BTW: Safe Mode log is also included in the logs.

A question: Is your OctoPi username really ******** ?

Thanks for the reply.

Octolapse plugin but turned off in the octolapse tab. Do you think it is somehow still doing something?
While problem solving a more sever version of this pausing which resulted in frequent jamming i would get a dialog before print could start. It was one of the reasons I turned it off in the Octolapse tab. I will try disabling the plugin and try a print again.

On the OctoPi naming thing, ******* is not the name. I have a program that automatically removes username, logins, passwords etc from any file when they are uploaded, Seems it must have noticed the OctoPi username and blanked it out. That was unexpected..

Have disabled Octolapse plugin. The move to the center of the print does not occur.
If the Octolapse plugin is enabled, but the Octolapse is turned 'off ' in the tab, is there a reason for why it may still cause this behavior?

I still get some pauses every 2 layers, elsewhere in the print, for layers <10. Also 3-4 pauses near layer 10, then seem to print normally without pauses after that. Note: these pauses are not the same as the previously described pause above.

If it is ok in safe mode, you have to find the 3rd party culprit by try and error.
With that amount of plugins quite an effort.
Maybe disable the fist half. It it is ok then, the culprit is in that half, else in the second half.
Then you can half the first half to do it again etc. Quite recursive.

Ewald_Ikemann, your right. I've started going through each with the 3rd party plugins turned off, and slowly enabling them in groups of 2-3. I am curious to locate the one causing the issue(s).
If you or anyone else has an idea on which ones are likely to not be contributing to the problems, your ideas would be appreciated.
I would very much like to get this working smoothly.
