@dc42 I'm adding some photos for posterity in case this works out and someone else wants to try it.
Diode from Digi-Key... Vishay V3P6L-M3/H
The "L2in" node is only available on the top side of the PCB. I lifted the plastic bar off the "OUT_0 Select V" connector to get access to VB_FUSED and wired up the diode. Then replaced the plastic bar.
Hi,
I've got a 6HC mainboard connected to EB3HC expansion board address 1.
The LEDs are blinking in sync. Both boards are at 3.4.6 firmware.
When I try to map the endstop on the expansion board, it does not seem to work and I get a CAN response timeout error.
Does anyone know what I'm doing wrong, or how to fix this? Thanks so much!
I cannot post my config.g because it complains I need a reputation 2 to post links even though it's just text.
My mistake... I'm sorry for mixing up the firmware numbers. I thought I had the latest firmware on both boards but I don't. I updated the firmware on the 6HC and it's now working.
Thanks so much for your help!
