Ive started an Openpnp/Duet config/gcode page for the Openpnp group. Please help keep the page accurate and up to date. The current example is based off my current machine a CHMT36V using a 6HC and x2 1XD's.
Thanks Wayne

Ok got comms sorted. I got this initially

Looks like the MISO line isnt pulled up locally on the the BTT board. I guess this makes sense as the board is meant to plug into 'step stick port' on a BTT driver board. In all the literature I read from BTT/Biqu makes no mention of pullups or active line jumpering. Any way pulled the MISO line up to 3V via 10k and now I get the following;

DWC is also reporting semi resonable values so now just some tuning and firmer wiring to get the ball rolling. I have a Duet PT100 dtr board coming from filastruda and I dont think ill have it for a week. I also ordered an Adafruit MAX31865 bob that should be here tomorrow so Ill follow up this thread on how that gos.

Huge thanks for this Forum and support, the best

@Phaedrux "You MIGHT be able to get away with longer length if you used a shielded twisted pair cable instead of a flat ribbon, but even so, SPI isn't meant for long runs."

I dont think shielding will help. The issue is increased capacitance and resistance with long wire runs and screws up the spi signal timing. The quickest check would be what others have suggested. Simply move the SBC closer to the 6HC using the original cable. If that fixes your issue no amount of shielding is going solve your problem. You will need to relocate the SBC next to the 6HC.

Will do, I need to get the mechanicals back together first.
If you dont know what this is, it's the aftermath drag pin machine crash. The pin with the bent tip slides up and down within the blue coil of the selenoid with the bent frame.

I hope to get fixed tonight and put some of my new and improved RRF commands to work

Thanks again.

@fcwilt THANK YOU! The schem answers all questions.
For my app I will drive an off board FET driver board via V_OUT's set to 12V.

@infiniteloop
Thanks. The issue I've had has been in regard to reseller sales/shipping itself and not Duet itself or 2ndary integration. Duet is without peer, and I have 7 different production machines using Duet controllers. I'm located in USA CA and have attempted to use a CA based vendor twice for Duet and each time the order has been filled incorrectly. This is extremely frustrating. Conversely, I started using Filastruda located on the opposite side of the country in GA. Ive had 6 different Duet orders with Filastruda with no issues and have received the orders much quicker than the CA base vendor.

This is just my experience and I don't know if posting this is of any help to anyone else.

...end of rant.
