V-MiniON bed heater - strange behavior
This behavior started happening a few days ago.
Heating bed to target temperature is flawless.
As long as NOT printing, the heater PWM is stable, no jumps, everything is fine.
A few minutes after actual print starts, bed heater PWM starts going all over the place, as well as reported bed temperature. This doesn't happen immediately, but roughly 6 to 8 minutes AFTER printing starts.

at a loss with Ratos configuration wizard
Unfortunately I can't get any further.
I have played the company more on the SD card and then transferred it to the mainboard, everything worked perfectly.
If I continue now and click on the check button, nothing happens.
Do you know this or do you have a solution?...
layer shift on newly assembled printer
Mega frustrating layer shifts on newly built printer.
Green piece was the first one. No shifts. But it was the only piece printed at once.
Then i tightened back belts.
Also printed two other pieces at once, that were good.
Then the blue pieces overnight. Layer shift on one axis....
Sometings wrong with stepper driver?
im trying to figure out what happen here... when i try to do a stepper buzz, all the steppers works, but not x. i get this message. would it be my driver thats given up?
Any ideas ?
The Belt is new the noise also :/
the upper belt in the left conner make noises and the belt looks after some prints a little but damadge :/...
Belt tension or something else?
So I'm having some slight issues, Not sure if this is belt tension related or something else.
Solution:
Turns out it wasn't actually my issue... The Pi was being throttled And I didn't realize it. It was the old Motorola Phone charging brick dropping voltage. Plugged it directly into the power brick on the Surge Protector and my issue's went away.
I lifted the nozzle a whole .120 and it was still doing the same thing. And then I was also having homing issue's after I made this post. It would only move the gantry about 20mm and then stop and report no trigger after full movement.
After changing the power supply everything went back to normal, I use a .040 feeler gauge to set nozzle height since its more consistant than a piece of paper....
Z wobble or some sort of problem with gantry?
Not sure what is going on, but I am having z wobble/banding on VCore 3.1. I've tried doing a bunch of different stuff to the z axis, checking everything and making sure it is straight and the lead screws are straight and seated properly and there's no binding. I am still getting z banding but it seems to be mostly only on the Y axis movement.
The pictures here are from the left and right side, which would be the y axis and the gantry moving. It isn't really there for the X axis though, which I'll add the pictures for the X axis below.
I've tried fixing the gantry, I've untightened and reset the mounting points to straighten it to see if that was the problem but there wasn't any change really. From the shaper graph, the "y" green line is the x axis which causes the second peak. I don't really know what I should be looking for, everything is tightened, the belts are all moving correctly on the pulleys. I'm at a loss, I'm not sure if I should be looking at Z or Y, or even what anymore....
