duet on mendel clash with ormerod

Hi all
I have set up my mendel with a duet controller using DC42s hot end
This works very well but if I run my ormerod at the same time the mendel keeps dropping the connection to chrome
The duets are on separate ip addresses and run without a hiccup on their own
what is causing this clash?

The clash is caused by all Duets having the same default MAC address. DC42 implemented a command to change the MAC address, so use his firmware and put the command in the config.sys file of each Duet (use a different MAC address for each Duet). Do a web search for "MAC address" if you want to know what it is. The LSb of the first byte of an Ethernet MAC address must be zero and bit 1 should be set to 1 for a locally administered address.

The command to use is M540 P{Mac address}

So in one Duet put a config.sys command such as:
M540 P0xFE:0xED:0xDE:0xAD:0xBE:0xEF

and in the other something such as:
M540 P0xFE:0xED:0xCA:0xFE:0xF0:0x0D

The standard RRP 0.78c firmware also allows the MAC address to be changed in the same way.

OK - I didn't realise they had also implemented it. So all Bob has to do is add the relevant commands to his config.g files.

Thanks, I'm glad to hear it! Have you mentioned this on the Mendel forum yet? Also, it would be good to know what you had to to do mount the hot end board on the Mendel hot end.

I will put this on mendel forum
I have a reprappro mendel with vertical x axis rods
The mounting for the hot end is the same as the ormerod so no mods needed
the only mod was to extend the x axis micro switch and reverse the extruder stepper
