Make sure to remove the MicroSD from the control board. Some SKRs with the CNC builds would have issues if you left a card in for some reason.
even if the card is empty? Iāll give that a shot after dinner.

Yeah, weird I know.
Not sure if the SD card had anything to do with it. I think the first firmware I tried to load was for the wrong board and it corrupted the bootloader.
Some combination of the following commands is what fixed it:
sudo dfu-util -d ,0483:df11 -R -a 0 -s 0x8000000:leave -D ./M8P_V2_H723_bootloader.bin
sudo dfu-util -a 0 -D ~/klipper/out/klipper.bin --dfuse-address 0x08000000:force:mass-erase -d 0483:df11
make flash FLASH_DEVICE=0483:df11
At one point I even ran this bastardization of the above commands
sudo dfu-util -d ,0483:df11 -R -a 0 -s 0x8000000:force:mass-erase-D ./M8P_V2_H723_bootloader.bin
I did take the SD card out. Iām too chicken to try to put it back and see if it still loads. Iāll play with the printer more tomorrow. I had a rough day of coding at work today and donāt really feel like screwing with config files anymore tonight.
Tomorrow night Iāll try to get the axis moving and get the probe working. I did test the two temp probes today by blowing a heat gun at them. The temperatures moved on the graph, so thatās working. Although I think I have the wrong thermistor type set for the heat bed.
Got up this morning and started going through the configuration checklist.
Tested out the two heaters, endstops, and stepper movement. Thatās where I stopped for now. I need to setup the probe next before I can home. I also want to switch the bed over to PID. I just copied the config from biquās github and it had the bed heater set to waterfall.
Testing out the extruder heater had me worriedā¦ When I first told it to turn on, it failed. I forgot I hadnāt plugged the heater into the board yet 
I did like how easy it was to configure the endstops. I went ahead and plugged in the z endstop even though Iāll be using the probe for z. That reminds me, I need to put the glass bed back on the heater.
I also need to figure out what type of thermistor I have on the heat bed. I didnāt update the config for that yet either.
Lastly, I need to extend the parts cooler fan wires and do some cable management on the printer.
Oh. And I need to find the filament stand I used to use with this printer. Itās one of the little simple ones where the roll sits on 4 bearings. Maybe I should print one of the holders that mounts to the top of the gantry frame.
So many little things to do before I can start melting plastic.

It all seems so simple then the more you think about it there are SO MANY little things that all have to happen too
I forgot how small this printer is. And the new extruder is closer to the gantry, so thereās clearance issues.
With the new nozzle offset, it looks like Iāll have about a 90x90mm build plate.
I have āhomingā working with the normal z endstop. I was able to jog the steppers. This machine is pretty silent with the new stepper drivers.

I was at this point this weekend, I was actually considering going back to Marlin, then decided to turn everything off and walk away for now, LOL.
I was at that point last night. Not with Klipper but just the entire build process. I was somehow thinking it was going to be quick lol. Thinking about it in big chunks sounds a lot faster than when you break it down into all the little things LOL. Having to make myself just pick a part and work on that till its done before moving on to something else. About to start and finish the last of the aluminum parts, then on to the next task LOL
Letās not forget that I also need to put new connectors on EVERYTHING. Iām just shoving the dupont connectors into all the spots, but I want to put the actual clip-in connectors on everything. Iām sure that will take a few minutes.
Oh. And I just remembered I wanted to setup a git repo for storing my configsā¦

LOL I just pull the plastic like we did on the SKRs and keep the duponts Iāve never one had one come off doing it that way
This older printer is a bed slinger. Itās been known to rattle connectors loose. The last controller I used I had a box printed that had strain relief to hold the wires in place.

I prefer the jsh-xt connectors to the dupont because they lock, but until recently my crimping skills were very much lacking, but now only slightly lacking, but improving. My v4 has the xt connectors which I prefer now. The mpcnc has rj45ās at the controller exit to dupont to the motors. With my z brake motor testing, Iāve spent a lot of time crimping connectors and gotten much better.

Only got 2 done before needing to leave for dinner.
Donāt forget kidsā¦ The spring pressure can be adjusted on your crimpers so you stop chopping the connectors off

Finished the night last night with the two endstops done and one stepper motor done. Spent most of my evening prepping for fiberglassing the kayak. Itās just the wife and I at the house tonight, so donāt expect much 3d printer progress.
