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

RE: Duet Mini 5 BTT MAX31865 Issue
@dc42
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

RE: SBC loses network connection, alot!
@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.

RE: Read Output pin state
@owend
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.

RE: 6HC power selection
@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. -
RE: Rating Duet distributers/resalers?
@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.

1HCL + LDO 0.9
I bought some 1HCL and https://www.filastruder.com/products/ldo-stepper-motors-with-encoder-for-closed-loop . I didn't realize these motors are 0.9.
I checked the filastruda listing again; Duet3D has tested these with the E3D Toolchanger on the X/Y axis with a 1HCL control board, and found they worked well.
But recall per the Duet site re 1HCL and 0.9 motors; We advise against using 0.9deg motors because the maximum speed will be reduced. The positioning accuracy in closed-loop mode depends on the resolution of the encoder, not on the degrees/step of the motor.
Is there a verdict on this? The application is for Z- neg head on a pic and place machine. The original application had open loop drivers, but lacked auto tool changing. New application will have tool changing and torque is critical.
thanks for any insights

Rating Duet distributers/resalers?
Is this worthwhile to the community? I've been very pleased with one reseller and very disappointed with the another when sourcing Duet products. Before calling out names I want to make sure that it is not bad form. I know I would appreciate a heads up for trusted suppliers and wish I could have avoided one in particular.

RE: M135 or Alternative
@dc42
Thanks David. I'm rethinking the problem. The issue I was trying to solve was potential 'tool' offsets of different pnp nozzle tips during mid job tip changes. The CP40 tips themselves are all similar length but tip to nozzle mounting depth seems to vary a tip change to tip change. Vacuum threshold was going to be the probe feedback.I not familiar w tool offsets in Openpnp, but that's not what is bothering me. The inconsistent mount depth of the CP40 is. I'm going back the Juki tips that I am familiar with them and they firmly mount at consistent lengths. Probing for the Juki tips isn't needed.
Thanks for the tip.

Duet3D Magnetic Encoder max cable length?
How long can the SPI encoder cable be and work reliably?

RE: M135 or Alternative
@dc42
Hmm, What about the first option of using the Zprobe along w an analog signal switch between my two measurement channels? A Openpnp script could handle the M42 ch switching and the Duet can just stream the single adc value.Extending the M950 per my pull request would never happen 2nd my lack of follow through
The comparator wont work as each nozzle tip size generates three different levels, ambient, vacuum part on, vacuum part off.
Ill need to read more about Zprobe. Thanks for the tip!

RE: M135 or Alternative
@dc42 I currently only have SE analog 0-5v for vac measurement. An atd to spi or i2c I guess would be possible, but then I would have to move the measurement circuit alot closer to the 6HC and away from the valves.
What would the max atd frequency be?

M135 or Alternative
I have a PNP machine using 6HC/Openpnp. Vacuum sensing is handled by temp0 and temp1. The temp sample freq is too slow for part detetcion or Z probing. I found M135 and https://forum.duet3d.com/topic/16698/m135-deprecated.
Is there any way to increase the temp sample freq >50hz? Or is there any other 6HC peripheral that is capable of sampling 0-5v single ended signal at >50hz?

btncmd panel lost after IP change
So my btncmd panels are gone in DWC after duet wifi IP change. Is it an issue with the IP change? All of my called macros are still in my macro folder. I dunno why the IP changed, I did not change it on my end...
