Looking good!! Can’t wait to see it done!!!
Well…I splurged and bought all black hardware. If you see them, I have a couple bags of black pulleys, could not help but get some black screws.

you using an skr for this build with klipper (until the pico thing gets sorted)?
Yeah, looks like it.
let me see if I can help with a printer.cfg file to get you started.

Considered Octopus Pro, or something else that can handle higher voltage (e.g. 60v), more drivers, integrated CAN Bus connector? Is this your go nuts and experiment build? Already splashed out for black pulleys, why stop there… fwiw Home Depot have a nice Behr matte black primer-paint spray that was helpful when I couldn’t cheaply/easily find black bolts/nuts hardware for previous project.
Not that kind of nuts, I don’t need extra drivers or higher voltage. This is my play with klipper build, then test some new filaments.

a couple notes on this printer.cfg file:
- in prusaslicer for custom gcode before (other slicer commands to send temperatures may vary):
START_PRINT EXTRUDER_TEMP={first_layer_temperature[0]} BED_TEMP={first_layer_bed_temperature[0]} - in prusaslicer for custom gcode after:
END_PRINT - uncheck the “emit temperature automatically” box (in prusaslicer) or it will go to temperature before doing the start_print macro.
- to get the right serial/usb device:
- click machine
- click mainsail.cfg
- click USB devices button upper right
- click refresh and verify your board is there
- click on the copy button to the right of the device that is yours
- paste it into the [mcu] section serial line in in the printer.cfg file below in place of what is there
This cfg is a work in progress and should hopefully get you started. No guarantees, I actually have not booted this config yet, so if it has errors, it will tell you what they are and you can iterate through fixig them, but it should get you close and I hope it is helpful. The A/B definitions may not be perfect, but it is easy enough to change. It is patterned this after the voron setup and Asa’s config, but they all had CAN and I didn’t, so it is different. The pins should be accurate, but you may need to remap as required. I’ll use this for the V5 with the ebay board I just got from you when I get the rest of the parts for it.

Here is mine for the SKR Pro. I don’t think any of us have one you can straight copy but between all of us it should make it easier.

I redid that config for this prototype system dimensions. If the outputs and inputs are plugged to the labeled parts, it should just work… the no guarantee part was in case I spelled something wrong as encouragement to double check it.

My fault. I only glanced over and for some reason thought you were running an octopus.
So minimal H2 cooling, probe, accelerometer?
I can add a little fake wall to hide things more,
Once I get this one dialed in, I can make it work with the Lite version.

I like it. The one on Ernest (v4) is leaning forward 45 degrees toward the user so it doesn’t hit the machine frame, but it sticks out the front of the machine. Will an original BLtouch fit in that mount? I may print one for my current setup. it looks good
No, I did look at it but it is soooo big. This extruder is tiny. That gear is right there, and the vent is on the other side. It would need to stick out further and probably be turned sideways.
The throat screws would get covered as well.
Where’s the LED lit logo? 
I couldn’t figure out how to make a more symmetrical aggressive looking hotend (like stealthburner) for my setup.
Being able to easily see what the nozzle’s doing is helpful.
What probe did you end up with? Did you tear down a BIQU MicroProbe V2.0 for H2 Series Extruders Ender-3 B1 3D Printer – Biqu Equipment, or something else?
Yup, that is the probe.
It goes against everything in my head to add things like walls just for looks, sometimes it does really add a good look though. I made a little one, going to give it a quick test print.

I have tried a bunch of times I can never get a light very close the extrusion, the nozzle is so close the heater block gets in the way. LED’s could work on the Lite, HF version since the heater block is so large. I don’t think I will add them there, though. Surely add some to the frame, the status indicator is pretty nice.

Have you looked at using LEDs like these??
BTF-LIGHTING SK6812RGBW(WS2812B… Amazon.com
There are 3 of them in the tool head on my E5+. 2 pointed down at the nozzle and one up top behind the logo. Really nice easy addition. And it turns out I have PLENTY left over lol

Can you actually see the extrusion, or just near it? The heater block always seems to cast a shadow. I guess I do always use some sort of heater wrap so there is even less room.
If I can’t light up under the heater block it doesn’t seem to be worth it. I just look as it moves. More wires, more stuff on the moving head is the last place to put stuff. If it can be lit up from the frame, that is much better in my book.

There are some pretty tiny LEDs out there, you could also build in a spot for a light pipe/fiber optic source, something like this:
Ignore the price because there are vastly cheaper options, that’s just one that looks like something I’ve used before.
