Wait a bit, he is making a V2 based on TMC2208!

Who? Source?

Stephan Watterott, the original designer of the Silent Stepsticks...

I'm not convinced by these. They seem to need 24V direct power plus a protection board O_o

This is not very different from the other ones...
None of them are protected against back-emf.

They do native 256 microsteps and can be configured via UART.

Now for standard 16 micosteps (or interpolated) the 2100 are good as well...

So, if i buy these tmc2208 and, for example, rumba board for my um2, can i reach same speed and other benefits of umboard and silent of sss at the same time? Is it real?

The TMC definitely outperforms the Allegro drivers.

I am going to upgrade my UMO as it is an easy and not that expensive update on the 1.5.x boards, but I am not sure I would throw away teh 2.X board from my UMO+ just for the stepper drivers...

can you make a 'dummy' tutorial of how you do this?
very interested....

Hi PeggyB!
Thanks for your interest.
I think the starting point would be to print/buy the parts you require to make your modifications.
If you have something in mind for your Ultimaker I'd be glad to help out.
Just send me a PM and maybe we can arrange a Skype meeting

More Updates!

My P.I.N.D.A. like sensor just arrived.
This is the ebay link of the item: http://www.ebay.it/itm/122206045078?_tr ... EBIDX%3AIT

I did test the probe on the bed and it works WONDERFULLY just like it does on a Prusa i3 MK2.

I did start re-working the design of the modular head I use in order for it to be able to mount this sensor.

I yet have to print this out, but I'm doing it as I'm writing here

Next to come about this will be to deal with the firmware :S

I have just upgraded the extruder to E3D Titan and ordered the silent step stick drivers.

I can say that the Titan extruder is DAMN QUIET! Works like a charm and I mounted it directly on the UMO frame in place of one of the X/Y motors (as I'm on direct drive).
The thing is incredibly small, I was surprised when I opened the box.
I only had a small issue with the 2.85mm filament guide as the hole was too small so I had to drill it bigger.
The parts for 1.75 mm filament instead were perfect.

I then added Neotko's mod to home at the bottom and did some firmware tweaks and improvement.

I'm working to switch to a direct extruder as of now so that would allow me to print 1.75mm flexible filament.
As the head will / may change drastically I did put on hold my work for the PINDA sensor for auto bed leveling (but I tested it working okish with the old head).

Have You considered Opt Lasers blue laser heads?
