yeah tose are definitely curly quotes. Must be using a Mac.

Hi,

Thank for your information, I have check a lot of videos, tutos, and other CR-30 informations.
I will update the printer with NAK3D motors mount, allready ordered and a replacement Belt. It's same belt material seen on Ideaformer 3D Belt printers. So I hope better than the original one.
I see the linear rail kit from NAK3D, but it's expensive and not sure about quality for long time use, I will do same kind of kit by myself with HIWin linear rail.
For the nozzle system, I think I will try with the original at the bigging, and switch with orbiter system or similar after first custom step...

@jay_s_uk
Is it ok to connect to LED strip in parallel? Would it work and both behave the same, as a mirror image of eachother?

@dc42 hello
thank you for the info. I will use V48. would V48 goes in the range of the power voltage well below the stepper driver rating of 60V?

If I use one NEMA 34 and four NEMA 23 together with the Duet3 6HC v1.02, would the correct/sufficient voltage will be distributed to the stepper motors by the driver? e.g V48 for NEMA 34 and V36 for NEMA 23

@Festivejelly Have you made any progress on getting your accelerometer connected? Do you have a PanelDue connected? If so, are you using both cables (ie ribbon and 4-wire)? @myersm1234 found in his thread https://forum.duet3d.com/topic/35460/accelerometer-not-found-on-specified-port/33 that disconnecting the PanelDue ribbon cable fixed it for him, though I was not able to replicate the problem in my bench setup.

@myersm1234 I set up the bench test again, with the ribbon cable and 4-wire cable connected to the PanelDue this time. My accelerometer behaved perfectly!

One thing I noticed is that if you run the command to define the accelerometer M955 P0 C"spi.cs2+spi.cs1" I61, and it goes through okay, you can disconnect the accelerometer and M955 P0 will still report that the accelerometer is there. It's only by sending the full command again that it actually looks for it, and reports if it cannot find it.

So I'm not sure why you are having problems. Possibly a damaged PanelDue cable, or that it ran near something that generated a bit of interference, or something else on your board is causing noise on the board that having the PanelDue ribbon cable connected exacerbates enough to drown out the accelerometer.

If people are having problems with their accelerometers in the future, I'll certainly try and remember this as a possible solution!

Ian

@brampie That could have shorted the SPI bus that the drivers use to communicate. Give the board a good clean off, then connect via USB and see if the drivers are available again.

Ian

@achrn
Perfect, thank you for the detailed explanation! Really helped me to fix my issue.

Well I think I know the prob. My power supply took a dump. The stalling came from low voltage

@KennethR happy to hear you were able to make it work and you picked up some valuable skills along the way.

No difference with the cover off!

@JeroenR it definitely won't be stepped up internally

@Phaedrux @dc42

Thank you both for your help, I visited the customer last week with a replacement Duex5 in hand and the issue is now resolved.

It was the board and not the ribbon cable, as I exchanged the cable first and the issue persisted. But upon swapping out the board as well, all function was restored and the machine completed a test print.

Two notes to close this up, I would recommend having a way for the expansion board to report these Short to Ground issues using the driver numbers included on the board (5-9) rather than the local numbers, because that was a contributing factor to me running down the rabbit hole on the mainboard rather than the Duex.

Second, we need to have a conversation about who is liable for the replacement board because I believe the machine has an extended warranty that is still active directly from Modix. I have the defective board and it's ribbon cable at my desk and can ship them back to you if you would like. Let me know what the best next steps are and I'll be standing by to finish this up.

Thanks again,

@SanderLPFRG if you're keeping the 5v powered throughout you'll be fine cutting all 24v.
If you're cutting the 5v power as well then you "may" have corruption issues on the pi. But saying that I have never properly turned off any of my pi's (running a mixture of SSD's and SD cards) properly and haven't managed to corrupt a system yet

@chrishamm did it work?

@misterjtc Hi, can you share your results, please? Is everything ok?
I want to get Duet 3 mini 5+ as well because of the tmc2209 drivers. Duet 2 wifi is better known to the community, but it has 2660 drivers without stealthchop unfortunately.

I would appreciate if you describe the steps needed to go through the upgrade.

@gloomyandy said in Recommended Canbus E3D Toolchanger Cable Management:

One thing I did change on mine was to modify the dock so that the bowden tube is routed alongside the metal band/wiring rather than splitting off as it does in the original. The bowden then goes inside the rear electronics area for a short way before being routed through the back panel back into the main chamber to the spools.

I've done that too for my Hemera tools.

@Exerqtor Do you find it more difficult to communicate with a different board than the Duet? Or does it remain simple with the CAN bus and just a matter of assigning some addresses?
I didn't know that Annex was stepping out of the open-source project. If I see that it doesn't work well, I'll get the ERCF. Even though I've already built the trad-rack. My real issue is that there aren't many configurations for RRF, and I'm not very skilled in 'free' programming. I like to experiment, but I don't have any studies that could help me. 🙂
