SOLVED - Downgrade RRF from 3.1.1 to 2.xx
-
Hi,
Trying to downgrade a fresh Duet2 ethernet currently in 3.1.1, to RRF 2.03
(I tried first to upgrade my config.g to comply with RRF3, but many changes are not working on this new printer, and I want first to test with a known valid version of config.g if the issues are on hardware or config side).The M997 S0 command is asking for the following files :
Duet2CombinedFirmware.bin
Duet2CombinedIAP.binHowever, the repo for version 2.03 has the following files:
Duet2CombinedFirmware.bin -> OK
iap4e.bin
iap4s.binShould I rename one of these iap files to "Duet2CombinedIAP.bin" ?
-
Why would you downgrade?
You should upgrade to, at least, 3.3.0.
I have 5 printers running 3.3.0 and they all work just fine.
If 2.x worked for you and 3.x doesn't it is a configuration issue.

@fcwilt we always have bad reason for not upgrading
I have a first (exotic architecture) printer still in 2.03, everything working well.
I try to commission a 2nd printer (same hardware than the first), with a new Duet in 3.1.1. I have some issues with a couple of I/O (PWM command to fans, link to a SX1509, ...). I want to be sure not to have a hardware or wiring issue, by testing it with RRF2 and the same config.g than the first printer.
Then if everything is working well, I may explore the new capabilities of 3.x ... -

If true and something is not working it is most likely a configuration issue.
My 5 printers were all different hardware. Some had Duet 2 boards, some Duet 3. They all work fine under 3.3.0.
But you do have to be sure you have made all of the configuration changes needed to go from v2 firmware to v3 - there are a number of important differences.

Upload the full zip file for 2.03 if that's the version you want to use. It contains all the required files.

Thanks.I'm using the Duet in standalone mode (with printcore link to a RPI 3B+).
Do I put directly the zip file in the /sys folder ? -
Ok, I managed to perform the downgrade.
I used the Duet2CombinedBinary.bin from 2.03, and the Duet2CombinedIAP.bin from the 3.1.1.
