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)...
RPI not powering on
Not getting power to RPI from the motherboard.. i pulled the rpi.. powered it from an external powersupply works and boots.. when i reconnect the rpi to the Vcore 4-500 the reaspberry pi wont power on.. First 3d printer build ever.. and i have no idea where to start trouble shooting
thank you!...
Is this belt tension or something else?
wonder if this is belt tension, zwobble or something else. ratrig vcore 3.1 300x300
..... Update .....
Problem: the carriage could move with the motors ennergized, the lower belt pulley setscrew had untightned and pulley was partially loose...
Bad stepper motor?
Started having issues with the straight lines essentially turning into gyroid😂 I believe I tracked it down the the T0's stepper motor having a very mechanical hard to turn spot that I could feel moving the print head, after taking it apart it is in the stepper motor itself for the hard to turn spot then it frees up and repeat. I've never dealt with stepper motors going bad much is this something that looks like it could cause this? In the pictures the White is T0 and the darker is T1 and yes i...
