Cannot Connect to Moonraker (randomly, frequently, during prints or just sitting there)
Hey folks.
RatOS will randomly drop a "cannot connect to moonraker" error, pretty regularly and without pattern it seems. It happnes both during printing and when there's nothing happening. I'll be connected to the machine, viewing my cameras or what have you, and then suddenly connection drops and it either can be refreshed and come back, or drops entirely untill I power cycle the printer.
Some more specific symptoms:...
Toolhead configuration cannot be deserialized
During the setup i get this error message when configuring the toolboard. Also the fans connected to the toolboard are doing the opposite, they are supposed to (running with 100% when they should be off and the other way around).
How do i fix this?
I have a v-core 4 in the base configuration with BTT EBB 42 CAN V1.2 toolhead....
Solution:
Try starting the config from scratch and selecting a different model and ‘start fresh’. Then go back and select the correct model
Move exceeds maximum extrusion
Can someone please tell me where I can increase the extrusion limit on my V-Core 4.0? I'm using a 1mm nozzle, and the default value is much too small.
Wrong hotbed temperatur.
I upgraded my printer with a Orbitool toolboard and after gone true the setup my hotbed thermistor shows 7 cellsius in roomtemp (not connected to toolboard BTW), i use a laser to se what the real temperatur is and ther is a differens of 17 degreas. i have tryed 3 different thermistors and its the same problem so it must be a software isue, i can find the pullup_resistor for the hotend but where is the hotbed hiding? cant seem to find it, and is there a bether way to callibrate the thermistors ?
and second whay is hotend powerdraw in celsius. can i fix that?...
Ratos 2.x
So I thought I had made progress. Long story short, memory card or the pi 3 crashed, so replaced with a pi 4 and new memory card. Had issues with Beacon calibration, but finally got past that. This is vcore 3. I have used superslicer since I got this. I chose something small to test print and I can't get it to start a print, not sure why. I'm using the same settings and same version of superslicer as I did before without any issues. Can someone point me in the right direction as to what in the world is happening here?
Oh, 1 more thing I'll add, I didn't have the Beacon on previously, new since the crash. So that is the only physical change, which means it's Rat OS 2...
IDEX layer shift
So just finished the bulk of the IDEX upgrade on my VC4 300 - everything looks ok. Configurator re-ran to update to IDEX, I have control of both print heads, etc. Went to print the VAOC parts and while the first layer goes down fine things seem to drift after that. It's almost like it loses track of where it is. Any suggestions? You can see in the attached image the second layer is offset by about 15mm X & Y.
Bearing clunk - but which bearing?
I dont consider my Vcore 3 to be very old, but I do wonder why sealed bearings fail, and how do we find which one?
If I push my toolhead diagonally, I can confirm the clunk is not from the linear rails (phew), since it only occurs in one diagonal, but I wonder if someone has a method to identify which bearing of that particular belt loop is the problem - I prefer not to dismantle it all.
And while I'm asking, why do these bearing fail at all - shouldn't they last for ages ( my belts are not overtight)...
