Over time build plate sinks in the rear
It seams like for some reason my build plate sinks in the rear after a while (weeks). I keep adjusting, but it's like I always have to adjust the front down to compensate.
Is there a better way to adjust this?...
Heater issue: Heater extruder not heating at expected rate
Hi. So, I been having this issue randomly for some time now and it's driving me crazy at this point.
My VCore has been working fine with the Rapido (not UHF) for some time now and I have been able to even print for 40 hours with no issues whatsoever. However, for the past three weeks I haven't been able to print not a single thing because of the verify_heater issue. I can see on the Mainsail graph that once the temperature I use for PETG is reached (245), it randomly ramps down between 20 to 40 degrees and most of the times is not able to catch up and start printing.
I have searched around here for this same issue and tried all the options I have found: Redoing PID calibration, changing for loose/broken cables (I even changed cables from another Rapido), changing the thermistor and even replacing the heating cartridge but nothing works, I will always end with this same issue at some point. Usually happens before starting a print, but it also happened mid print multiple times. ...
Extruder heater continues heating past target temp
I set it to 60C, it starts 100% and quickly drops state to 0%. At 70C I turn it off (and luckily it does).
It seems the temp sensor works fine, its just that it continues to heat at full force and its no longer being controlled properly.
What could be the issue with this?...
Mintemp error
Hi guys!
I am new here and in 3d printing so I am still confused about all.
I have this errror that stopped my print that was going overnight and now I have to trow everything 😠. It says MINTEMP error. My nozzle temperature went down in moment and everything stopped. I noticed later that while I move head around, similar temp jumps are happening. I have pictures attached. When head is steady, everything is ok. Can somebody help please? Sry for bad english...
Random misbehavior
My printer is been giving mixed signals lately. One moment everything is fine and I am starting to trust it and the next it does some very random stuff. For example, I was sitting next to it and it started doing the bed mesh from the middle randomly (I was like I don’t think I did adaptive mesh yet) then it smacks into the gantry 🥲 luckily I was there to stop it. I restarted then it started the print just fine with no problem doing the bed mesh this time. Also sometime the next on the next print the bed mesh sometimes runs at a slower speed randomly. I would love to solve this mystery. Let me know if anyone ran through something like that or has a solution. It’s a new build on vcore300 3.1 with mostly the common stuff.
Also at the start of the print lately it Started doing what is shown but printing fine after....
tmc5160 stepper issues
Recently I had both my x and y 5160 steppers die now I'm back running the 5160's @48v again but on my 3rd print I get the error shown below same as last time. Cant power up the motors . Unfortunately fan is off in fault state and when I arrived the stepper drivers were very hot!.
Before I left I checked steppers were cold to touch, all looked well printing fine.
She printed for the last week on 2209 @ 24v no issues. Now I can't keep throwing 5160s at this I've only 2 spare 😬.

Pisa Tower prints on Y axis
Hi there, i recently applied OS and hardware upgrade. So my VCore 500 runs under RatOs 2. I have changed XY motion system by Vcore 3.1 and BRS Tensionner. I also put a Hextrudort on a VZ head.
My problem is when i print a part it systematically comes out with a diagonale issue on the Y axis only when i print in layer by layer mode. But it comes very nice out when I print them in vase mode. I already made accel and speed test to be sure it do not comes from pulleys or coupling....
error
Hello, after doing a fresh install of ratos because it has been such a long time since i have used my printer, aswell as cleaning up some wireing. I have been face with a error? (Picture attachment) I have tried to do the following things in the klipper guide on how to fix this issue. Here is what the guide reads:
**"I keep getting "Unable to read tmc uart 'stepper_x' register IFCNT" errors?¶
This occurs when Klipper is unable to communicate with a tmc2208 or tmc2209 driver.
