New update on STMBL

As far as I'm aware V4 used an obsolete power semiconductor this (v5) is a forked project with a new design.

The origingal project is here but has not seen updates in a few years:
github.com/rene-dev/stmbl

Note that v4 does not support motors above 2kW either.
You might want to ask for updates over on this site as there does still seem to be some activity there:
app.gitter.im/#/room/#rene-dev_stmbl:gitter.im

As far as I understand, this v5 supports imput 220vac 4 kW 4.5 kW motors, but is it not suitable for mach3? Doesn't it provide 5v pulse/dir?

As far as I understand, this v5 supports imput 220vac 4 kW 4.5 kW motors,

What makes you say that?

My network supports max imput 220vac, I am not in an industrial environment.
This may be possible but 220v input drive electricity going to the motor can be up to out drive motor 380v but I don't think it is needed because 220v 15 20A would be enough

I hope that Kuka Robot will be enough to operate in my home.
Ac motor drive
but need installation guide and details

It is suport step/dir sir?? Because original stmbl are suported right, if posible open the step/dir interface mate, so we can used for mach3 or grbl, thank u somuch.

 
Do you have any information on your chopper circuit for the HV DCLink rectifier? I would love to see how you rectify your power? What type of capacitance have you settled on for the bus? Also it might make sense to right angle PCB for some electrolytic caps to reduce ESR. I know the wire runs are short but i would be interested to see a scope trace of the VBUS during operation.

PS. I was working on updating the STMBL for edge connectors and changed out a few parts including the IPM but I really like your implementation!  
 

i have an Old Abb irb2000 thats just sitting there, that i want to revieve.
it seems that this could be a way forward.
What kind of setup are you using for the rest of the control chain ?

I wanted to bump this thread and inquire if anyone was using the STMBL v5 on their LinuxCNC projects? With native SS support, small size and support for straight rectified 220v I have always felt it was an amazing solution. It is pretty well documented but I'm wondering how challenging it is to tune the drive for the motors once all setup? The instructions seem fairly straightforward but it is hard to know until you try!

Also big thanks to Freak for reviving this project!

I suspect that the problem is getting hold of the actual hardware?
