Upgraded my toolhead on RR3.1 and the printer has gone full stupid.

Gong to the commissioning steps and it seems to "home" okay but when I run z-tilt, it's making awful noises almost like I have a stepper backwards. I have checked all the cables, and I am at a loss as to what could be the difference between the two. Also sometimes, when trying the z tilt, the console shows no trigger after full movement, but the pinda is way off the plate either forward or off to the side. Now I did have the controller fan off, is it possible I nuked a driver?...
Solution:
Come to find out some of the drivers were bad, I did have the bed crash into the nozzle while not paying the required amount of attention

metal "klunking" noise and seemingly loosing steps

I wanted to print the skew calibration test and in the beginning it went well but after like a minute I startet ro hear some metal "klunking" sound seemingly coming from the linear rails and it also seems like it lost a few steps. I have no clue what happened because the initial Z offset calibration print went without any problems. I have no idea what could have caused this other than a problem with the linear rails so I think its more fitting here than in fix-my-print.

skipping A and B's

Im working on getting RatOS running on my 2.4. I am running LDO 42STH48-2804AH's for the A and B. Those steppers are not in the setup wizard so I picked the 2504's. But Im still losing steps in "Performance Mode". Does anyone know if there is a way to fix this without replacing these steppers? I know they are not the "Optimal" steppers but they are very good steppers.

Bed level issue - wave in my bed mesh and copy / mirror prints on T1 result in waaaaaay to low z

Hello. I believe I have an issue with my stock bed having a wave in it. Below see the images of the hot and cold bed meshes. This results in mirror and copy prints on T1 having waaaay to low of a z offset and making mirror / copy unusable. Any and all help would be appreciated. I think I might need a new bed.

Issues with Dragon HF

A while ago, I had a clog in my Dragon HF hotend. I was unable to clear the clog, so I pulled the hotend apart and got it out that way. I suspect the clog had occured in the heatbreak. After clearing the clog and reattachting my heatbreak, I had a filament leak where the heatbreak attaches to the heatblock, I suspect I didn't tighten the heatbreak well enough. So I cleaned everything, reassembled everything and printed a benchy, wich went fine. Now at the next print, it seems (I'm not actually sure) like filament has leaked again but this time from the nozzle sides (which has been properly hot tightend). I'm not sure what could be wrong now? My print detachted and on inspection there was a filament blob under the silicone sock, which leads me to believe there was a leak at the nozzle. When cleaning the block after the first leak, I used a metal pick to clean up the threads where the nozzle and heatbreak screw into. Might I have damaged them in this way, causing a leak? Do I just stop bothering and order a new hotend?...

Random "Error during homing (....): Communication timeout during homing" at start of prints and VAOC

I have had a lot of random errors when I start prints. It can be on X, Z or beacon (never had it on y), I see no pattern on what or why this happens. It can happen anytime from the first homing of xyz - to the last homing before printing. I'm then not able to start the print again until I restart the printer. If I use emergency stop to to this (easy one click to reboot(reset everything) and start the print again, it will start the print (after doing this 1-5times). Nothing has been changed during this process to start the print. I can do all kinds of homing outside of prints without any problems, and have tried homing zyx and z-tilt before starting print without any luck. I found some other treads about this, but no solution to my problem....
Solution:
I found an earlier post on lowering resolution on my cameras, and this seems to work for me. I haven't had any problems for a week after lowering the resolution to 640x480

Trouble understanding head selection and temp settings in Mainsail using Orcaslicer

Hi everyone, and thank you for any help on this. I have created a temp tower to print using T1 and it is printing using the correct head. My question is about Mainsail and extruder heating. Initially T0 and T1 came up to temp BUT now T0 is dropping in temp for the temp tower, T1 is stuck at 230deg C, just backwards and weird. T0 shouldn't even heat if not being used to print. I followed the Orcaslicer setup putting in all of the gcode for an IDEX printer and filament. Any ideas? Thanks!

Turn off part cooling fans when klipper is booting / offline

Hi guys, I have V-Core 4.0 with IDEX and can not figure out, how to turn off the two part cooling fans (4028) until the klipper boots up. They go on full blast for a minute or two in the beginning, when klipper is offline (no PWM signal). There is this guide in the documentation https://os.ratrig.com/docs/guides/4028/#my-fan-runs-at-100-until-klipper-boots, but I can not make it work in the current setup. Klipper neither accepts "shutdown_value" in fan section, nor "enable_pin" works due to it being used multiple times. I have a standard IDEX setup/kit. Is there a way to turn these fans off in configuration, until klipper boots up or do I have to rewire the fans (GND) to do so with Octopus board?...
Solution:
it should be similar to ``` [fan] pin: !fan_part_cooling_pin cycle_time: 0.01...

VAOC not working

I continue to get Webcam stream not found. If I leave crowsnest as default I can make the VAOC a webcam and see an image but when I change crowsnest file to what the IDEX commissioning nothing seems to be working. I have also check WebRTC test pages to make sure I don't have a browser problem. I can see images with the VAOC Camera and others cameras hooked up to my PC. Additional infomation is doesn't appear that my crowsnest.log is regular being updated. I have looked over under thread "Vaoc - not working" an try those steps to troubleshoot and have made no progress. I have USB on RPI - Beacon, VAOC, and ControlBoard and on the waveshare I have both Toolheads ...

X cariage moves slightly along the Y axis while homing X axis

Whenever I home the X axis the whole X cariage moves a little bit along the Y axis. I tried to loosen the belts because I thought they were too tight but it didn´t change anything. I don´t really have any experience with this sort of stuff and when I tried to look on Google for the answer I couldn´t find anything so this is sort of my last resort. I have a VCore 4 500 IDEX but since the manual said so I didn´t put the Hybrid belts on yet.

bed won’t heat

Weird sound from belts.. can’t find the cause

Weird sound only happens going one way. Checked tension and is correct in relation to florent broise pdf about belts. Both are 56hz. Tried with 59 and 62 as well. Does no difference.....

Hotend moving back and forth.

I can move my hotend back and forth when it is hot but it won't move when it is cold. I made sure the screws at the top are tight. Has anyone seen this problem before? My other hotend doesn't move at all. I've attached the video but there is much more movement than what is in the video.

Error evaluating 'gcode_macro _START_VAOC:gcode

Error evaluating 'gcode_macro _START_VAOC:gcode': jinja2.exceptions.UndefinedError: 'extras.gcode_macro.GetStatusWrapper object' has no attribute 'z_offset_probe' I started to get this error after updating to v2.1.0-RC3-20-g90dce855.
