3DP1000 Duet Ethernet Conversion
-
@veti Yep. Prior to connecting the steppers, what I did was wired it all up, grabbed the multimeter and tested to make sure that each wire was connected all the way back to the board. I pull out the E0 connection on the ramps board and connected one end of the multimeter to there and then to the corresponding one at the stepper end. Worst thing that should have happened as far as I am aware is that the motors should have spun the other way if it was backwards. Instead it went haywire when attempting to turn the motors then stopped and became unresponsive.
Not sure if it is a voltage issue or not.
I went and bought 2 backup ramps boards, and a few other things just a stop gap should it all go pear shaped before i can get this done.
Cheers,
Brad. -

That's not exactly correct. You need to identify each the two phases and ensure than each pair of wires connected to each motor coil are connected to each pair of pins at either end of the connector. https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors
Follow that link, then scroll down to the part about connecting stepper motors to internal drivers.
-
@deckingman Yep, I did that with the multimeter on the wires out of the stepper to identify which two were in the same phase and I kept them paired together.
I was able to identify which ones were in the same phase on the board based on the A/B notations on the PCB. -
@cherno-alpha Fair enough.
-
@deckingman Just checked out your blog. Insane printer and good luck at the show with the Duet 3 ( Which I just learned about on your site, so thanks for that).
I might look at the Duet 3 for my scratchbuild project (when I get around to it). -
@Cherno-Alpha The newer 3D platform machines run on duet controllers. Here is a link to the firmware config files which should be reasonably similar to your setup and may give you a starting point for settings (attachment to the link below).

Note that the axis motors on the duet units are connected via the duet servo expansion board: https://www.filastruder.com/products/duet-expansion-board

@nhof thanks
@Cherno-Alpha also the Warwick Design + Make team upgraded theirs https://twitter.com/LizBish94/status/1136329317745614849
So it can certainly be done!

@nhof @T3P3Tony
Thanks for the info.
I saw that the newer ones have been changed over to duet boards, the main difference with mine i think is that my x/y/z axes are steppers rather than servos.
Looking forward to getting this done as I think it will provide a much better 3d printing experience for me. Especially with a bondtech. -
@nhof ,
With the expansion board [in case i need to purchase it as well], is it the cable and expansion board, or just the cable? -
@cherno-alpha Shop page looks like you can buy it either way.

The Duet Ethernet should be here tomorrow.
A few other items I will be doing to the printer is an enclosure for the print area. Pretty important for me as I do a lot of ABS printing (helps I make my own filament as well).
The next is the Z-Probe for mapping the bed. I had a look on this site and saw the Piezo sensors. They look to be pretty much perfect for my purposes. Mapping the 1m x 1m bed is pretty important especially if there is dips in the bed. Any one used the piezo sensors? They are mentioned on this page here. https://duet3d.dozuki.com/Wiki/Choosing_a_Z_probe . Once that or similar is installed, I will probably do 15 points on the bed to map it out. Essentially one measurement every 25cm. -

beware if you'll be using the online configurator with power loss function

@bearer Is this like the Power Resume Feature?
If so, I dont use it and I am not a fan of it for two reasons.
Firstly, if you are not nearby and everything cools down, the print will lift from the bed.
Secondly, the ones that I have tried re home before commencing again. They never go back to the exact same spot and is always off just a touch.
If the print shits itself, I just restart it. -

yeah. but the online config tool has a bug and renders the config useless if you enable the power loss / resume function. but if you don't plan on using that then go forth and configure
without worries:)with one less worry:) -
@bearer There will be plenty of worrying when configuring it. Never really done this type of thing before, but I have figured out most of the other things with printers. I am an expert on repairing my Raise3d machines
-
@bearer The Configurator code has been fixed on Github (and network has been put back at the beginning of config.g, so at least people should be able to connect to DWC), just waiting for the online configurator to be updated.

@bearer Actually, it's already been updated and M911 in config.g has double quotes around it, but you have to clear cache to make your browser use the latest version. From Christian:
Check for version 2.0.1
Can be seen on the start page. If it displays v2.0.0, clear your browser cacheAnd my mistake, the network code hasn't been moved back to the beginning yet.

The Duet has arrived, I am looking at a piezo bed levelling system for this, is it fiddly to set up and is it reliable? Alternatively what is the most user friendly bed levelling system? The bed is glass.

Therein lies the rub. They're all pretty picky in some way or another. Pick your poison.
-
@nhof Just looked at the expansion board and I need to get one, problem is the Australian reps dont have any at all so will have to get them from overseas. Yay for freight charges.
