V3 to 3.2 : DUET v. SMCNC connectors?

Post by nurbie »

SMCNC sold out on DUETs so I shopped elsewhere.
DUET connectors are warned against in V3.2 assembly walkthrough:
When inserting the wires in the white Molex KK connectors, make sure you're using the connectors we sent you in the kit, NOT the ones included in the Duet box!

I'm guessing this is because of the different lock tabs on the connector inserts(wire ends)?
Any other reason why the connector warning is there?

If no SMCNC-DUET kit then clip the crimped ends off/go with the DUET kit parts, correct?

Looks like the stepper connectors that fit the V3 RAMBo will work with the DUET(no locks/nice and tight!)

If unnecessary, stop me before I chop it all up! :shock:

Nevermind.
Made up new connectors with Duet supplies.

Couldn't pull post...

The crimps and shells supplied with the Duet are made by Wurth Electronics. There are some very small dimensional differences between Wurth and Molex parts, which means that Wurth crimps won't lock into Molex shells. I'm guessing that the advice from SeeMeCNC is for a similar reason.
