Hello Everyone,

This may be a long shot but I am trying to find further information about the two PCBs in my RV4.
I have attached a picture of each, but would like specifically to know the pinouts of the the connectors, as in what each pin does and what the signal to expect etc. The larger board is the one fitted on the arm and the small PCB is the one fitted to detect the slots in the lower driver wheels.

Any information on these boards, such as functionality or RS232 data etc would be really helpful.
The larger PCB has a MAX232 chip on it so I assume that this board has some serial comms.
If that is the case, does any know what commands or data to send to it or what data to expect from it, format etc.

Thanks
Paul

Hello all,

I want to replace the motor drive belts on my RV4S.
As many of you know these are marked up as T2.5-950

My question really is where do I buy good replacements from?

Searching the net brings up many suppliers from RS to eBay with various prices up to £30+ each and and different types of materials etc.

My existing belts measure exactly 12.6 mm wide, so I assume that's what I should replace them with.

What is the ultimate drive belt for these machines?

My belts don't look too bad, but I am 'upgrading' my RV4S to run with OpenPNP and a Duet3 6XD controller and really I would like to put new belts on as I have the robot assembly ripped apart at the moment and it would be good to know they are new without any issues.

If anyone is interested in this, I could start another post documenting my progress, which may or may not be successful!

Thanks
Paul
