3HC 1.01 48V
-
We have a 3HC V1.01, we bought it thinking that it could have been used at 48V but we realised the release 1.01 we have can't go higher that 32V. Is there a way to use it at 48V maybe changing a component or it is just impossible?

@highfreq i would suspect its the same as the changes required to a 6HC

@highfreq there is also the possibility of using an STM32H7 board in expansion mode and using 48v with that for motor control.
The SKR3 EZ and Fly-Super8Pro both support 48v input natively and the SKR3 can be used with external 5160 SPI drivers that support 48v (e.g. the Fly-5160-HV Pro's).
Otherwise if you want to stick to Duet3D hardware, you would have to go with a 1HCL -
@jay_s_uk Thanks we prefer sticking with Duet hardware, i was thinking about 1HCL but we would like to have more i/o like the 3HC. Since 3HC has a 48V version now maybe we can change just few components to make it work.

@highfreq I didn't realise the 3HC had gone 48v.
Maybe check the schematics to see whats changed? -
@jay_s_uk I am a software guy, not really good when it comes to hardware but if someone tell me what to do i have decent soldering skills and tools.
On the official documentation it says:
Input power voltage Version 1.01 and earlier: 12V to 32V, version 1.02: 12V to 48V

@highfreq the changes cannot be retrofitted to a v1.01 3HC unfortunately.

@t3p3tony Ok, thank you anyway.
