Connecting Stealthmax via Stealthmax pcb v2

I am trying to get my SM to work with the printer and I ma getting odd behavior. It seems to use the same id as my t0, I thought I got around that by defining the path, now what happens is klipper never starts because it cant connect to t0 or the SM, or the thermistor on t0 reads a crazy high temp. Disabling the SM config and a hard reboot gets my back into klipper. WHat can I do here?

VCore 4 does not print straight but wavy lines

Hi everyone, my newly built VCore4 400 Hybrid doesn't print a straight line but instead prints wavy lines. The closer it gets to the sides of the print, the more the problem gets and the waves become stronger. In addition, you can hear something tensing up or pressure building up, as if the motors aren't running synchronously. I've attached a few pictures to clarify this, here I deliberately worked with underextrusion to illustrate the problem and show that it's not a filament problem. What I've already tried: - Belt tension...

Hotend not heating on new vcore 400 Build

Hi all, Hope you're all doing well and thank you in advanced I have just finished up building my vcore 4 500 full kit supplied by RR Everything but the hotend is working, I'm getting a temp reading from the thermistor which is working correctly (tested this manually warming it up with a hair dryer) but when I try to heat the hotend it just doesn't heat (throws a klipper error stating it's not heating) ...

Wondering how to change the thermistor offset?

A long time ago I changed a thermistor offset in my printer config because I had a huge variance with what was reported and what the temperature actually is..... fast forward to today and I am putting in a new hotend but I can't remember the setting that I had changed. Just curious if anyone knows what setting it is in the printer.cfg file?

Frequent tangle detection on Smart filament sensor for Orbiter 2 on V-Core 4 400 IDEX

My prints fails due to frequent tangle detection, specially with opaque filament. I can read on Orbiter page: "The detection is activated when filament the pulling force is increased over 1.5–2 kilograms of force for more than one second. The wear of PTFE tube can also trigger tangle detection due to the high friction force. Warning!!! The tangle detection can be falsely triggered by high friction in a long PTFE tube, hard-turning big filament spools, or high printer acceleration with an improperly secured PTFE tube." https://www.orbiterprojects.com/smart-sensor-for-orbiter-v2/ But if I manually restart the print, it proceeds for some minutes untile the next tangle detection. Do you think the "pulling force" or the "one second" can be changed in configuration to reduce the false positives?...

MCU 'toolboard_t0' shutdown: Timer too close

Right IDEX belt issue

I've redone the belts 5 times now on my VCore4. With y belts installed and not installed it's the same behaviour. When I move the gantry in y direction the right belt wiggles a bit. The left one stays still and I can't find the issue
Solution:
It was a missplaced shim 🙂

Issues upgrading V-core3.1 to toolhead v1.0

I am upgrading my v-core 3.1 to a toolhead 1.0 (orbiter 2 + rapido 2 + EBB42 1.2) following a print failure that destroyed most of the printing head. Both the main board (octopus 1.1) and the toolboard (EBB 42 1.2) show as "detected but not responsive" in the configurator. I have eventually updated the firmwaare by SD card but the firmware on the toolboard doesn't seem to have been updated. ...

Vcore 3.1 IDEX nozzle wipe

I designed an arm that has a wire brush built into it so I can potentially wipe my nozzle before tool changes. I am having trouble finding where I could tell the printer to "brush" the next tool to remove oozing and blobs. Got any ideas?

Filament grinding HELP

Vcore 4Printing ABS, filament grinds every print and either clogs nozzle or stops extruding. Tensioned using vez method and/or mikl method and still grinding. Helge suggested to check the gears to see if they are centered on filament path. They where not. Fixed that and it still grinds. Open to suggestions. Im suing the stock punkfill abs profile. Some suggestions i found online are lowered retraction (now at 120), and checking filament path. I also lubed the filament spool holder to make it move easyer...

Octopus 1.1 Firmware Issues + Magic Smoke

Howdy folks, am on the last legs of building my VC4 400(the scary side when you plug it in for the first time). My Octopus board originally successfully connected to the Pi before I did the electronics installation (registered in DFU mode in the configurator). Throughout the installation, I followed the instructions to the best of my ability but ran into two separate issues:...

IDEX Part Cooling Fan Issues

Hi All, I have just finished my IDEX upgrade and I am running into issue with my Part Cooling. The error is: pin PA0 is an alias for fan_part_cooling_pin I used this guide https://os.ratrig.com/docs/guides/4028 when I first built my VC4 XY & Hybrid but since upgrading to IDEX I run into this issue. I've used user overrides as below in my printer.cfg I am using the BTT Octopus MAX EZ board....

VC4 making deep gouges in print bed

When my VC4 (With beacon) prints, it makes deep gouges in the bed (Measured in excess of 0.2mm with calipers). When it does a beacon contact probe, it's fine, it makes no marks. When I was printing earlier on the stock RR PEI plate, it was fine. However, since swapping to my BuildTak Nylon+ build plate, I am having this problem. This build plate is much thicker than the stock RR one....

Dual Extruder Set Up Issues

I'm trying to run two orbiter extruders inline with Belay to prevent filament feeding issues on my 500mm VC4. The second extruder pulling off the spool does not move at all and I cannot find what I did wrong (the extruder does work when plugged into the toolhead, so it's not a mechanical failure). I'm using the following config, and after several hours of searching cannot figure out what I did wrong. I've tried using the SYNC_EXTRUDER_MOTION EXTRUDER=my_extra_extruder MOTION_QUEUE=extruder but only ever get the error The value 'my_extra_extruder' is not valid for EXTRUDER Please help, I've spent hours on this and I know it shouldn't be that hard to get working ```[belay my_belay]...

X Axis Skipping on print Startup

Hello 🙂 We have an odd problem with our ratrig vcore4 hybrid. About every second or third start of a print there is a audible buzzing noise and steps are skipped along the x axis. This happens only during the start print macro right before the priming blob. ...
Solution:
In case anone was wondering: We were able to fix the problem. The issue was the lower belts being tightend too much. Loosening them fixed the issue.

VAOC LED ring not working

I've been able to confirm that the VAOC camera is working as is the VAOC fan, however when I try to trigger the LED ring to light up it doesn't seem to want to light up. I've only tried this via the little flash light Icon on the VAOC screen.
