from were I can download the pcb layout and who make it the cheapest ? Thank s!
from stmbl.
the next revision is far from complete, dont bother stocking parts. Make v4 if you cant wait.

Hi guys.
Who is interested in IRAMs can find some at tme.eu
At the moment they declare 63 pcs in stock.
Thee ones that I ordered came from Poland as I remember
The price is 22€ each for 3+ pcs
from stmbl.
Yes, Infineon discontinued it after they bought IR.
New design is in the pipeline.
from stmbl.
IRAM256-1567A2 or IRAM256-1067A2 can be used as replacement, but they only have 15 and 10A, but thats plenty for most servos.
they are still available at mouser.
from stmbl.
Have you chosen a new part for the next revision yet? I'd like to get some boards made soon so would like to start gathering components.
Many thanks for this project!
from stmbl.
All A2 models seem to be out of stock now. The A models can be bodged in:

Any progress with new revision?
from stmbl.
yes, but not ready yet
from stmbl.
can we replace IRAM256-2067A2 with ON semiconductors- STK551U3A2A-E ?

No this does not work with 3 low side shunts (connected emitters of the lower igbts).
The next STMBL version has a discrete 3 PH bridge with TO220, but the design is not ready yet.
from stmbl.
okay, thank you!
STK554U392A-E: this is 15A version and this works with 3 low side shunts

will it work?

I know I feel like a total nag. I was going to build one of these, the bought a full CNC instead....but it turns out that machine can't get "Polygonal turning" (I want it for gear hobbing) so I'm going to add a spindle I can synchronize. I was planning on the full 2Kw. I may see if I can beg for one of the older chips. I'm not requiring this....now....as I've got some other design and building to do of the mechanical parts. Any hints as to when it will be out? Any beta's? as long as its not going to catch on fire, I'm game :)
from stmbl.
I have a source, they got 20 units of the IRAM256-2067A2 in Stock left, but these costs 44,06€ per piece. If you think it is worth it i can order these IBGT Modules. I am from Germany (Berlin).
from stmbl.
I'd like to order three!
from stmbl.
I’m no github expert, otherwise it contact you off of this (if it’s possible). I’d order 4. If you can get my contact info, just contact me direct. I’m in the USA, so I know shipping won’t be the easiest!

from stmbl.
sounds interesting, any more info about the machine?
from stmbl.
@rene-dev can yo give a guess or an etimation when the next version / generation of the STMBL Board will be published - that means without the obsolete IRAM Chips from Infineon therefore with an other IBGT module?
I am undecided or it is worth to build the actual design with the last IRAM256 Chips if maybe in a couple of weeks there will be no more need for this IBGT Module and it is replaed with a new Version with estimated Production Lifetife for ne next 10+ years. And of course a lot cheaper than the last IRAM Chips in Stock now.
from stmbl.
It won't be ready in the next couple of weeks.
from stmbl.
so we are talking about months or years?

If the Vers. 4.1 of the stmbl works with the IRAM256-2067A Module, i will give it a try. But i have one Question left: whats the difference between the IRAM256-2067A and the IRAM256-2067A2 IGBTs?
from stmbl.
the way the pins are bend.

@rene-dev STK554U392A-E looks to be pin compatible, do you have any thoughts on this?

Infineon IKCM series seems to be a good replacement, for example IKCM30F60GA. It would require only minor modification to the existing design.

Hi Rene,
I am very impressed with you project. I know the question would I ask was asked many time but answer was not exactly for my question. Could you tell me if the new version of stmbl for TO220 will change only the HV power board or also control board ?
Thank you.
from stmbl.
the logic board will change slightly to keep the isolation distance (the cutout for the HV mounting screw moves a bit)
from stmbl.
Hello @crinq any news on the new version? thanks :)
from stmbl.
Hi ! I have a question before starting to build the v4.1 stmbl : all versions have the same pcb layout ?
from stmbl.
V4.3 pcb data is there: /hw/kicad/v4.0
but you should try to source the iram first
from stmbl.
Hi Crinq,
Can I omit some components (not solder, eg SN65176B) if I need only encoder and step/dir inputs ? I want to check firstly the connection between PC and STMBL board.
Thank you.
from stmbl.
yes, that is possible.
from stmbl.
Thank you Rene,

Shouldn't this new infineon IM393X6FXKLA1 part work?? It looks like the replacement for it, although they don't say that... It's obviously not directly pin-compatible, but the data sheets are almost identical.
from stmbl.
DIP parts don't work in the current form factor.
from stmbl.
The IM393X6FXKLA1 is a SIP part but it doesn't have the forward bent legs like the A2 version of the original power IC. It would be a similar bodge to the "A" model as for angle, but the pinout is different. With re-routing of the power board it looks like it would work but the angle is not good for the form factor
Reworking the power board -for- the DIP package would actually probably be the easiest scenario as the power IC can still sit on the bottom of the PCB screwed against the heatsink. I may actually give this a try, the power PCB section is alot more simple to deal with, it's mostly just mechanical concerns with mounting. I didn't fully study the datasheet, but I think the IKCM20L60GDXKMA1 would work for this.
from stmbl.
there is no space to re route it properly with this formfactor, feel free to try.
from stmbl.
is there somebody trying a solution?
I am going to try may be the IM393X6FXKLA1.
from stmbl.
Hi.
Anyone can sell me 1 pcs stmbl?
Sorry for my English

Hello, did I understand correctly the IRAM256-2067A2 can I replace with the IRAM256-2067A in the PCB version STMBL 4.3?
Thanks Axel
from stmbl.
yes, but you need a custom heatsink/case/mounting solution
from stmbl.
Hi, it may be a bit late, but please ShadeTechnik have you succeeded with IKCM20L60GDXKMA1 or other part?
any news for this wonderful project ??

All A2 models seem to be out of stock now. The A models can be bodged in:
Hi sir it posible to change the iram with this chip IKCM30F60GA???
And also i just want to used step dir comunication only ( i want to used mach3) so can i remove some parts??? To save more money??.
