kent closed T4418: Idler misalignment as Resolved.

This is resolved with the washer added in step 11 here: https://ohai.lulzbot.com/project/dual-extruder-v3/hot-end-tool-head-assembly/

kent closed T4419: Idler bolt is rubbing on back of large gear as Resolved.

This should be resolved with the addition of a washer in the idler lever assembly (step 11 here: https://ohai.lulzbot.com/project/dual-extruder-v3/hot-end-tool-head-assembly/)

@tutley, yeah on the m3 screw between the idler and the printed part. I've been putting them on the side towards the back because that helps prevent issues like T4419.

@kent where is this washer going? on the m3 screw between the idler and the plastic part?

Steps 10 and 11 should be updated here to add a washer, I think this will solve this issue. https://ohai.lulzbot.com/project/dual-extruder-v3/hot-end-tool-head-assembly/

karrad reassigned T2040: V3 Dual Extruder Thermal Runaway Post Thermistor Fix from karrad to lansky.

@lansky Do you feel we still need to be tracking these, or has the SB addressed the issues? (I am guessing the few we have rad reported were do to material defects.)

With PLA and other materials susceptible to heat creep, an enclosure is not recommended.

@kforrest Last time profiles were changed, was june 18th but it was just a name update on T2173. We have also added in some experimental profiles, but we have not changed the existing settings.

logan added a comment to T2378: PLA melting in heatsink.

This instance the heatsink fan was working, however the customer reported thermal errors including a runaway.
The photo below you can see where the filament swelled considerably, so much so that it took the shape of the printed part around it.
(Some had commented that those look plier marks, but upon closer inspection its the layers from the extruder body)

@anolen How long does it take to recover from the drop? A drop is expected, along with a quick recovery

anolen added a comment to T2338: PLA profile affecting extruder temperatures.

I have been doing testing with a Taz 6 Aero. After talking with @karrad he explained that Cura's "Initial Fan Speed"+"%" is always active, it cannot be turned off, so when it says "0%" it is only going to remain there until layer 2 when it calculates the percentage appropriate when taking "Regular Fan Speed" and "Regular Fan Speed at Height/Layer" into account. I have brought down the fan to starting the 2nd layer at 5% and I still get a 6 degree temp drop (same as 15%), my toolhead was indeed soldered. Any Thoughts?

anolen added a comment to T2338: PLA profile affecting extruder temperatures.

I ran a few dual Poly PLA prints and couldn't get a temperature fluctuation with our profiles. Dual V3 Poly PLA Profile is good for now, moving on to the Taz Aero

I don't think I have a V3 Dual that has had thermistor work recently, I do have Gladiola's that did.

karrad added a comment to T2338: PLA profile affecting extruder temperatures.

@anolen Start with the V3 dual extruder, and than on to gladiola. The 40w heater cartridge in hibiscus should be fine to help alleviate this.
