homing z
I am currently working through the commissioning step by step.
When I click on the button (see picture) the printing plate moves upwards, so I have inverted all three Z-motors in the printer.cfg. now everything seems to work correctly, but ...
When homing, the printing plate now moves all the way down and does not stop “chattering”.
Are the buttons in Klipper wrong or am I thinking wrong or ...
Is the problem in front of the monitor?...
Solution:
So undo the Z motor inversion and you will be fine. The sound you heard when it hit the bottom was the motors trying to pull the plate through the bottom of the printer. I hope you did not leave it making that sound for very long, it can burn out the motors
After a day succesfull printing..Troubles about stepper motor driver to hot and toolhead behavor.
Ik can't find any solution. After a new main board, now again troubles with stepper motor drivers.
And very annoying noise and jerky movements of the toolhead.
Checked everything, no loose parts, belts tensioned, no chafing parts, could not find anything causing this....
Bed Heater Failing on long heating segments
Been printing at 50-80 degree bed temperatures no problem. Just recently wanted to start doing some ASA and went to heat my bed up to 105.
Started the first print, got a heater error. Looks like at about 100 degrees it stopped getting hotter. Restarted the printer, and with the temperature already fairly high I turned it on again. It got to 103 before it randomly stopped heating again. One more time, starting at 90, and it was able to get to 105 and hold it no problem.
The best I can tell is that something is going wrong with extended 100% power input. That sounds like issues with the power being provided, but I'm not sure how to test that. I have a multimeter and all the tools, I just don't want to probe around without knowing exactly what I should probe....
Gaps on Pause Resume
I am looking for guidance on how to fix a small gap that happens when I pause and resume my printer after filament runout.
Every time I resume with new filament the print shows a clear gap at the resume
What setting or adjustment can I make to fix this ?...
RatRig v4 500mm electronics/controller fan weird behavior
OK the printer is up and running, making very nice prints at pretty quick (if not super fast) speeds. But I've run into a weird problem with the electronics enclosure fan not turning on. I have the single, 180mm fan setup. Forgive me if this has been solved already, I did look around on this channel, but haven't been able to find a solution. Thanks.
The fan is (was) wired up as per the build manual on PD12 (Octopus v1.1). It worked fine at first but stopped working after a few 10 hour prints. The fan works when I apply 24v from an external source.
The ratOS dashboard shows the controller fan (PD12) as running, but it doesn't turn....
Beacon calibration failing during comissioning
I'm just assembling my first RatRig printer (first DIY, but fifth printer overall). I'm no stranger to DIY and the build went smoothly. My printer has passed virtually every commissioning step but one:
BEACON_RATOS_CALIBRATE
I've read a lot here about causes of this error, so I've tightened every bolt on the printer, I've tried hot-tightening the nozzle, changed the nozzle - everything I can think of. I've checked there's no play in the print head, my belts are evenly tensioned, but I always end up with the same error.
...Solution:
Figured it out, there was a tiny bit of "stuff" (not sure what it was) stuck to the build plate and that was throwing off the beacon. Scraped it off and passed with flying colors!
Layer shifting during Skew Calibration Print - VC4 400mm IDEX
Getting layer shifts in prints. Could it be belt tension related? I'm not used to using resonance graphs to tension belts.
Cat pissed on my printer. Need new parts. What do you recommend?
Title says it all, printer got fried as the cat pissed on the rpi 4 and SKR PRO V1.2. Everything else looks fine, but need to replace those two, so why not upgrade!
What is the go to for the SKR Pro replacement?
I have had a big hiatus from the RatRig discord for a long time, so out of touch with the new parts available
