So since last post, the Voron has been turned on and ran through the complete initial setup. All the motors were reversed but everything moved as expected.
It was beautiful! I will never get over how cool it is to see automated machines in action, especially knowing what’s going on behind the scenes.
Some problems I ran into during this setup phase:
- Inductive Probe. Following the generated 2.4 guide with the diode on the inductive probe, I could not get any detection out of it. I started digging around online forums and the Voron discord for any advice but I couldn’t find something that pertains to my issue. What ended up being the solution was looking at the Octopus board itself, which was a Pro 1.0.1, when the guide was a Pro 1.1. You’d think a newer revision wouldn’t require a cable mod to be reliable but by removing the diode and attaching the inductive probe to the PROBE port as a singular 3 pin connector seemed to do the trick. The standard deviation proved it to be reliable enough, even when done hot, so I have yet to find reason to investigate further. And if any problem arises well…time for klicky probe.
- Controller fans. A minor swap, the original unbranded controller fans the kit came with were noisy and whiny. Not enjoyable at all to sit next to even at 40% power. So i swapped them out with 12V Noctua A24x15FLX fans. Remember to install a step-down converter to take the board’s 24V output to 12V
- Camera. By far the most annoying part. I bough a Pi Cam 3 which was supposed to be relatively easy to integrate, plug and play. But not matter how hard I tried digging into forums and the discord, I also couldn’t find pertaining advice. I tried messing with the config.txt and got the ‘
vcgencmd get_camera‘ to show ‘supported=1′ instead of =’0’. Progress but I had no idea what I was doing or where to go from there.- Attempted to interface with the camera by swapping out the SD card for a fresh PiOS installation to see if something within Crowsnest or Klipper was causing issues, but that didn’t seem to be conclusive.
- Then I realized something…all the voron guides and Pi guides about the camera utilize application names from older OS revisions. Alot of discussion with libcamera back in Debaian 11 Bullseye and further use of rpicam in Debian 12 BookWorm. The newest revision, Trixie, that I originally installed both the PiOS and Klipper, has no mention. Probably because it’s too new having been released 30 days prior. Classic new driver/OS moment.
- One down revision to BookWorm later and the camera popped into life as if nothing ever happened.
A couple frustrating nights later and the printer made its first plastic poop of many to come! I was thinking of installing a wiper piece like the Bambu machines because I noticed my Ender 3 likes to ooze during heat up from leftover extrusion. Maybe this wont be an issue with proper Voron tuning though.
The only print I had time to complete at midnight was a bed level check. And my god, it was perfection. The extrusion rate was pretty spot-on from the base configuration and I saw no raised plastic on the ends of each nozzle infill turn, a common thing I noticed with my Ender 3 that resulted in the nozzle dragging on the 2nd layer. I want to just full send print a Benchy on the printer when I return to work and compare out-of-box to a tuned printer.
Stay tuned!
