Ok. It's been a while since I've updated in this thread. If you've been following along in the 'what did you do in the garage' thread, you may have heard some of this.
About the time we were getting iced in, I was testing and failing to figure out why my Marlin based controller was refusing to use the bed mesh. I tried all types of settings all the way up until I would have to flash a new firmware on the board to do any more testing. I've always hated Marlin and only tolerated OctoPrint. So this was my best excuse to finally switch to Klipper. I have Klipper running on my older bed slinger, so I'm somewhat familiar with it.
I had also bout a new Manta 8 board and CMBD, but I haven't wanted to go through the trouble of swapping out the controllers because I'd have to design new mounts, put new ends on some of the cables, and half a dozen other "I don't want to do this" stuff.
BUT! I have a spare Pi4 doing nothing. So I tossed Klipper on that and did a flash of the SKR Pro v1.2 controller that's already on the printer. 2 seconds later and I had the Klipper software talking to the controller. This was the first day of icepocolypse. By the end of day two, I had the printer moving around, but some of the 'add ons' that I have on the printer weren't working yet.
Throughout the week I continued working on the printer in the evenings.
As of today, I have the following working.
* printer flashed to klipper
* Pi4 running Klipper software
* Klipperscreen working
* Z_tilt working
* Bed mesh working (the whole reason I was doing this)
* Chamber heater working
* Exhaust fan working
* Ambient temperature probe to help validate if chamber heater is needed (don't bother setting it if ambient is higher than set point)
I've also started making progress on two upgrades I've been putting off
* EBB36 has been installed via USB-C and input shaper enabled and working Katapult and Klipper firmware installed on EBB36
* SFS v2.0 filament sensor (initial pin selection and brain storming for where to mount done)
What I'm still waiting on parts for
* USB-C breakout boards
* removing the huge umbilical I have going to the print head and replacing with CAN either via breakout boards or a U2C that's being delivered
* Install and configure the SFS v2.0
What I've discovered in the process
* The reason the bed mesh looks ugly is the huge 6mm aluminum plate I'm using for the heated bed has an ever so slight warp in it

.
If I put a straight edge across the back of the print bed on the aluminum plate itself, you can see just a touch of light in the middle of the back edge, meaning the two corners are slightly higher. The bed mesh should be able to adjust for it, but I may need to consider rebuilding the heated bed. This was not a cheap bed. It's 300mm x 300mm with a magnetic build plate, AC high-wattage heat mat, and insulation.
I did get one print done AFTER setting up the input shaper and all ghosting is gone! So that's a good thing. The bed mesh is working now, so that's a good thing. And Klipper is WAY easier to configure than re-flashing Marlin after every change.
