This Issue (shown in pictures) happens pretty frequently.
Any idea why?
Logs attached....
MCU Shutdown (only on idle) VC4
Everything prints fine, I last had it printing for 22 hours and it came out with no issues. As soon as the printer is idle for a couple hours, this error comes up.
Abysmal Flow
On my VC3.1 i am getting extremely bad flow. I have replaced the Orbiter, i have an identical nozzle to my VC4 (both new), i've put the filament directly into the head without using the ptfe tube, i'm using identical filament, and the most conservative stock PETG print profile from Ratrig. All of it and I am getting bad flow and crappy prints on my VC3.1 and great prints on my VC4
Here are two pictures of the same part, one on my 3.1 and one on 4.
Any idea on where to start?...
Z-Offset is not saved VC4 - firstlayer
Hello,
i purchased a VC4-300 with the hybrid kit.
Everything looks alright but now i having problem with the first layer. I always have to change the z-offset down during the few first seconds. Its something around 0,1mm, then the first layer is okay. After save config nothing happens.

very odd temp graph

Failed homing of tool heads on V-Core 4 IDEX 500
When homing T0 tool head goes to the correct position but does not move back causing the error. Also T1 tool head moves in the incorrect direction after the T0 tool head triggers the end stop. I was attempting to follow the idea commissioning guide but the commands do not seem to work for setting the dual carriage.I have double checked the configuration of the motors and they seem correct. Is there a setting that needs to be adjusted in the configuration or did I just miss something?
Solution:
So I after going throught the configurator many times, it deleted the VAOC setup code from the printer.config file. After I copied the code back into the printer.config file I was able to continue through the guide. I also found that the T1 end stop had gotten smashed and was stuck.
Firmware SHUTDOWN: MCU fried?
Hello everyone,
After a few weeks I booted my VC3.1 again and now it crashes when I try anything (homing, heating up, etc.). Also, the 4028 fan no longer starts at 100% when booting up, which it used to do.
I have had an Octopus 1.1 installed since October 2021 and never had such problems. Could it be that the MCU is defective? How should I proceed with troubleshooting?...
IDEX Problem 2nd Layer move
Hi, i updated v-core 4 hybrid to idex. since them i cant setup it to correct work.
I done everything in the guide, all looks fine. VAOC Calibration is correct and absolutly fine.
When i print 1st layer test all is fine, so i calibrate my first layer....
Solution:
OK i think i fixed it, Problem is Orca Slicer, there ist no IDEX to Choose, so i used my Hybrid Configuration.
In PrusaSlicer all work fine. Why Orca Slicer doesnt can do IDEX?...
Move out of range during bed mesh
I am getting a move out of range error when trying to bed mesh. The values don't seem to be out of range, so I'm confused.
