What would you build if you were starting again now?

Basically, it's impossible to make a single board that meets all needs including CE certification and a desire for smaller size.

Have you considered populating components on both sides, consolidating connectors, etc, to minimize size?

A small footprint can be a strong selling point because it will simplify retrofitting existing tool head designs.

@ajdtreyd i could write a thesis with all the edits i made to the V2. Starting from new cf arms with ball joints made by myself because at the time no one was selling it. Another cool part i made was the mount for E3d V6 (started with V5 ). It was really cool to design and it has a lot better cooling and support for mini ir probe.

Nice graphic.

How do you change the nozzle? The graphic doesn't show all views of the design.

@fcwilt not perfectu but used this to assemble

I always used the .4 nozzle with that delta. I have a nozzle fun pack, but only used with the Voron for testing them.
You can look it there: https://a360.co/2USEGD9

an these are the real parts printed with the V2 (consider all belts and carriage are 6 years old and should be replaced probably)

I found this Knipex to work very will with my nozzle exchanges. The jaws are smooth and parallel and it has leverage that allow to easily apply sufficient force.

@zapta now i have a dragon hotend so no more problem with spinning heater block! E3D served me well in the years, but it's time for them to update their design.

@mikes I gave up on the V6 a few years ago after the heat break kept loosening in the heatsink during prints. I've been using a cheapo Chinese hot-end for a few years that cost $15 when I bought it, plus replacing the supplied crappy fan with a Sunon mag-lev type for another $7. It has set screws to hold the heatbreak in the heatsink, and a metal bracket that is screwed to the heatsink to hold the fan. No more rotating heater blocks or melting, rotating fan mounts. It came with a 50W heater and cartridge type thermistor.

I also have a dragon but with a E3D round grove interface.

Once I will have my voron up and running will see how I can convert it to the two-screws type mounting.

I've got a couple of "no name" units something like these.

The design is like the right image but with the plated copper block of the left image.

The fan mounts to the heat sink via the four threaded through holes - for those that like push/pull fans.

It doesn't use grub screws to hold the heater/thermistor cartridges which is too bad.

The V6 mount removes leaving two threaded holes.

I bought two of them to see if I liked them (I do) but now I cannot find them again. The inventory of vendors on AE seem to change with the winds.

@mikes, after reading your post I looked again at my grove mounted Dragon and realized that if I remove the groove adapter, it has 4 screw holes that I can use with the Voron Dragon variant. Thanks for your post I will have a proper Dragon with a single hand nozzle replacement

(The documentation of the Voron leaves so many details out to a point that many steps require extensive research in the Fusion 360 model, youtube, and discord).

@zapta that's exactly how i mounted it. However you should always use 2 hands for nozzle swapping... twisting force on the x carriage will be a lot less and prevents damage
