CoreXYUV with dynamic load\force balancing.

@deckingman I think your wheel budget might just exceed my whole printer budget.
Gives me nightmares just thinking about it...........

This is great and crazy altogether! I seriously love it! If I had a CoreXY, I guess I would just copy this build because it's so cool - totally independent of necessity.

We have a saying around here that you should NEVER sum up hobby and/or pleasure budgets

Great work Ian. I might have an old RAMPs board + some stepsticks lying about that can be used to get you those two other drivers so you can have 5 colour + dynamic load balancing.

Thanks Tony - that's kind of you. Hold fire for now though. I've a lot other stuff in hand at the moment and 5 colour plus dynamic force balancing isn't high priority just now (given that I can easily have either\or).

@deckingman silly you, we are watching.

@brunofporto Actually, I had already used all 10 of the Duet plus Duex5 drivers and didn't much fancy the complexity of adding two external ones. So at the moment it's either 5 extruders, or 3 extruders with dynamic force cancelling but not 5 extruders and dynamic force cancelling together. That will have to wait for gen 3 Duet.
But changing from one configuration to another is simply a matter of swapping two motor connectors on the Duex5 and uploading the appropriate configuration files - about 2 minutes max.
It's easy to use motors 9 and 10 on the duet2 itself without expansion. They are present on the (unused) LCD connector and it's just a matter of using two external breakout boards. Like on this image:
-
@token47 Yes I know, - and if you look a couple of posts up, Tony has already offered to supply the hardware. But it's still a fair amount of wiring, and some configuration changes. Both of which would have to be changed yet again when gen 3 Duet comes out. As and when that happens, I'll be gutting out all the wiring so I don't see much point in adding more at this moment in time.
As I have no immediate need to print 5 colours plus use the dynamic force balancing gantry, it's not worth the effort at this time. If I desperately need to print something using 5 colours, all I need do is swap two stepper motor connectors and upload the original config.g and homing files - about 2 minutes max (oh and print it slow by my standards which is still fast by most peoples
)BTW, starting as we do with drive number 0, it would be drivers 10 and 11, not 9 and 10, as drives 0 to 4 are on the main board and 5 to 9 on the Duex5.

Huh??? Has someone crept in to my study and installed a hidden camera that I don't know about? Have the GRU started to take an interest in me? Is that white Transit van parked down the road not what it seems?

Depends on what it seems to be. If it seems to be a surveillance van than everything is right.

Dunno. It's got blacked out windows and is bristling with aerials. There is a satellite dish on top too. I guess the occupants are just watching TV. That would explain the blacked out windows. Oh good, I can relax.......
We ought to end this here. Much as I like the fun, this isn't really the place...

Do you think making the frames heavier can reduce the vibrations that are seen on the frames ?
Industrial machines use cast iron base for their machinery to keep it rigid. Will this work on a 3d printer as well.
Thanks

@hussainsail2002 Yes. A cast iron frame would be good ( but perhaps a little impractical).

Looking at the picture, that printer has enough aluminum extrusions for 5 printers

Yes, pretty much. But then it does have a five colour hot end, 5 extruders, and 5 axes ( 7 if you count the load balancing gantry).
-
@deckingman, that's impressive, not to mention the saving of 4 nozzles and 4 duets.
-
@zapta Oh it's not much of a saving and the print area is only about 400 X 400 so probably less than 5 separate printers. On the hand, using all 5 melt chambers and extruders I have demonstrated "real world" printing at 300 m /sec which in the region of 5 times faster than what many people print at.
