Topic: Solidoodle's Sanguinolou Rev 1.3c vs Reprap Sanguinolu Rev. 1.3a

On my Solidoodle3's electronics there is a sticker labeled "Solidoodle Rev. 1.3C". On the PCB I only see "Sanguinololu" and a url to the Sanguinololu Reprap wiki page (don't have permission to post links yet).

Is there a difference between Sanguinolu Rev. 1.3a and the Solidoodle branded Sanguinolu labeld as Rev. 1.3C?

Re: Solidoodle's Sanguinolou Rev 1.3c vs Reprap Sanguinolu Rev. 1.3a

Not that you'd be overly concerned with.  1.3c is also not official.

The last 'official' board is 1.3a, there is an 'updated' 1.3b that is the same but has updated MOSFETs of an SMT variety and uses the atmega1284p. It also featured 4 pin endstop connectors for use with Opto-endstops.

1.3c, if thats what its labelled as, would be a privately made derivative of 1.3a or b. Based on my memory of the Sang supplied with my SD3 - it certainly doesn't have SMT MOSFETs and features only 3 pin end-stops... so it looks like 1.3c is some bastardisation of 1.3a backported to 1.3b... and then supplied with an ATMega644p instead of the more common (and larger) 1284p.

The talk of the upgraded MOSFETs is a little misleading on the 1.3b as they never upgraded the tracks on the PCB, so the limitation remains that with any decent current draw, you'll burn the current off the FR4 before the MOSFET gets hot anyway...

Anyway... nutshell version; No, theres no difference worth worrying about at an operation level.

Re: Solidoodle's Sanguinolou Rev 1.3c vs Reprap Sanguinolu Rev. 1.3a

I do have this same print board. It's indicated sanguinololu rev 1.3C, with a big solidoodle tag on it.

Maybe an evolution made by solidoodle.

I find it hard to go change values, Mine run the marlin firmware, and I couldn't find any way to connect to the firmware or to reprogram it.

I wanted to add a controled fan on my hot end, but I guess it will be impossible for me unless I change my printer motherboard.

Might consider it for later.
