Sovol SV08 Multiple Motion System Upgrade.

[dwuk]

Added tool board wiring - looks like there are not enough connections for the 3 fans - so might have to run some extra cables from the main board. I have shown wiring for 4 fans - but I think only 3 are used.

Revised Toolboard wiring with the help of @jay_s_uk and @T3P3Tony

Toolboard comparison - need to now work out which way up to place board and physical wiring. Ideally I want to be able to go back to Sovol board - so will have to work out some adaptors.

Next job is the power supply upgrade. The stock PSU is tiny - only 6.5a. I've got a 20A PSU from my WeedoX40 - so will put that in there instead. Need to decide whether to take the @TeachingTech approach- and put it in the same place as the existing PSU - which involves cutting some posts off.

Or go with @JohnSC's approach and mount the new PSU at the bottom -

Then for placement of Duet Boards. The Mini5+ board hasn't arrived yet - but it can be inside somewhere. I'm thinking of putting the Duet 6HC below the existing board - here maybe

Will involve cutting out some new holes to give access to the sd card, usb-c and ethernet. This pushes me towards the teachingTech approach to PSU placement.

In the end decided to go for this model as first attempt at PSU mounting

PSU Installed and design for Duet Holder done.

@dwuk Duet3 6HC board now installed - now for lots of wiring up.

[dwuk]

Starting to plan for expansion boards - looks like there is room,

Tool Distribution board and first Mini5+ needed for Dual Gantry, with further Mini 5 probably needed for IDEX - unless I can reduce the stepper requirement - by using less for IDEX and Servo's for Z Hoppers.

@dwuk This is all such an amazing project, along with your work on splitting the slicer output for two tools to print at the same time. Keep up the good work, and thanks for documenting it so well!

Good progress made on Duet6hc commissioning. Power and first 6 steppers wired up, and firmware upgraded.

Think I will try and see if I can get some movement tomorrow - before tackling the harder problem of the 1LC wiring.

Old board and wiring left in place for now - if nothing else it will be useful for it to provide the camera feed.

@droftarts. Thanks - really enjoying the project so far - I can see why people spend so much effort on printer upgrades and self builds. Will be really interesting to see whether parallel printing is practical.

interesting to see whether parallel printing is practical.

I'm sure there is a niche for it, same as for tool changers or MMU-printers. Each system has some drawbacks, here:
Building/commissioning/homing and maintaining perfect z-height will be a nightmare.

[dwuk]

@o_lampe Agreed Automated alignment, homing, maintaining perfect z-height are all essential, plus also speed, reliability, filament colour/material management & slicing.

In terms of niche MMU - I use the AMS on my BL printers 99% of the time - always for filament selection for single colour prints - but also pretty often for 4-11 colour prints -

I wasn't sure how much use I would get out of a 2nd identical multi colour printer (which I bought to double my printing speed) -

In my usage scenarios when I am using one of the printers I find I end up using the second one too for at least half of the time. It's usually only filament management that stops me from using the 2nd one even more often. i.e. Not having two sets of every filament needed. I've got a few ideas on how to solve this problem too - with some sort of automatic on demand filament roll splitter.

Tool changers I agree are more niche - probably due to the expense of having so much print head hardware sitting around unused for 99% of the time, plus also being limited on the number of colours supported. I think MMU/AMS type multiplexers are more practical for prints with many colours in them - but 2 to 4 extra 'tool changer' print heads I think could help speed up print times and reduce waste quite a bit without adding massively to the cost. A solution that only changes the nozzle and hot end would be even more useful too.

Building and Commissioning I would see as a separate problem - which would ideally be solved by a manufacturer taking up the idea.
