I don't think it should have any impact, but in my case there was a marked improvement with this change) reverse the way the stepper motor was plugged in and set it to inverted in marlin config (no why this helped. adjust the supply current to the extruder I was able to make a few changes which significantly helped things in my tests: I've discussed this with a friend who also recently upgraded to a Hemera and he's seen similar issues with his machine (Ender 5) and it looks like there's a few other people complaining of similar issues in this and other forums as well. It also seems like a heat creep issue, but sticking a thermistor into the heatsink or between the motor and backing plate only shows 40-45C (this is admittedly not a great way to take a reading, but it's all I have). It prints great for a while and then stops extruding.Īt first I thought my nozzle was clogging, but after messing around with it some more I'm pretty sure that's not the case as I can't extrude after a jam, but if I manually pull the material out and feed it back in it's fine for a few more minutes. This happened three times so I switched to a newer roll of 3DSolutech PLA (200C hotend) and saw the same issue as with the Raptor PLA. I then switched to some old MakerGeeks Raptor PLA (235C hotend) and started to have issues with the extrusion stopping suddenly a few hours into a print.
#HEMERA RETRACTION SETTINGS UPGRADE#
After the upgrade I printed for about 20 hours using PETG without any issues (240C hotend).
I just upgraded my AM8 with a Hemera hotend and I'm running into some trouble with extruding PLA.
