OctoSlack causing layer shifts #126
Description
I've been suffering from layer shifts in my prints. After checking belt tensions and checking for other mechanical issues, I suspected plugins might be the cause. I did a search by enabling/disabling plugins and narrowed the primary suspect to OctoSlack. Here's the data:
| Plugin | Run1 | Run2 | Run3 | Run4 | Run5 | Run6 | Run7 | Run8 | Run10 | Run11 |
|---|---|---|---|---|---|---|---|---|---|---|
| DryRun Plugin (1.2.0) | enable | disable | disable | disable | enable | enable | enable | enable | disable | disable |
| Firmware Updater (1.12.0) | enable | disable | disable | disable | enable | enable | enable | enable | disable | disable |
| Octoslack (2.2.0) | enable | enable | enable | disable | disable | disable | disable | enable | enable | enable |
| Preheat Button (0.8.0) | enable | disable | disable | disable | enable | enable | enable | enable | disable | disable |
| PrintTimeGenius Plugin (2.2.8) | disable | disable | disable | disable | enable | enable | enable | enable | disable | disable |
| Prusa ETA override Plugin (0.1.1) | disable | disable | disable | disable | enable | enable | enable | enable | disable | disable |
| Resource Monitor (0.3.5) | disable | disable | disable | disable | enable | enable | enable | enable | disable | disable |
| Slicer Thumbnails (1.0.0) | enable | enable | disable | disable | enable | enable | enable | enable | disable | disable |
| Tab Order (0.5.12) | enable | enable | disable | disable | enable | enable | enable | enable | disable | disable |
| TemperatureFailsafe (0.2.3) | enable | enable | disable | disable | enable | enable | enable | enable | disable | disable |
| LAYER SHIFT OCCURRED | yes | yes | yes | no | no | no | no | no | no | yes |
| >25hrs | ~19hrs | ~17hrs | >25hrs |
The data appears to implicate OctoSlack, but of course it's not conclusive. It could just be a rare problem and I'm often running with OctoSlack enabled.
I have enabled logging for OctoSlack, but it appears that logging only covers maybe 3 hours. So I'm not sure if the logging I have covers the most recent layer shift. Also the log is long and contains private info like names and tokens. So let's narrow down what we're looking for in the logs and I'll scrub a relevant portion to post.
