Pin 1?
-
Hello,
I am rewiring my stepper motor cables as the cables shipped with the AnyCubic delta kit were a bit short for their own TriGorilla (ATmega2560) controller, so I am making new longer length cables. Its a minor issue, but in reviewing the DUET-E (EtherNet version) schematics the connector symbols are not keyed to the layout drawing that I have been able to locate. As I don't use KiCAD, I can not view the silk layer of the board components layout keyed to the circuit drawing, else I wouldn't ask. And so, where is pin 1 located on the DUET board stepper motor connectors…eg, which end of the connector? I could move the pins around later if things don't work right, hopefully doing so won't cook anything.
Thanks in advance

Pin 1 has a square pad on the underside of the board, the other pins have round pads. If you reverse the order of the wires, all that will happen is that the stepper motor will rotate in the opposite direction, which you can correct for in the M569 command in config.g.

DC42,
Thanks for the info, and not intending to sound as though I'm complaining, but would be convenient to be able to reference that info without my having to dismount the board from its enclosure, or have the info cited (pin 1 marked with a dot or triangle or depicting a square pin) on your reasonably good 'Visio' style layout/hookup drawing.
Frankly, compared with a lot of other stuff out there, your support efforts and docs are pretty good.
Thanks,

I see theres is more and more of us upgrading or replacing Anycubic's Trigorilla with duet wifi!

MayDayOfPlay,
After expending around 6 months fabricating a wholly homebrew Rostock delta. Using my mill, I machined all of the brackets, frame components, etc, but I did not use 2020 T-Slot knock-off 'profiles' or T-Slot. My frame components were fabricated using Aluminum 'U' profiles from All Metals, a Los Angeles California metal supply vendor. For the corners, which was difficult, I milled a tongue and lap arrangement so that the frame peices seemlessly overlapped and then secured with M4 bolts and Nyloc nuts. That arrangement made for a very rigid and robust frame. But the project was taking ALL of my spare time and then about 2/3 completion, I had to drop the project due to family issues. My wife was raising hell! Seven months later when spare time again emerged, well, I just didn't have the steam to restart the project, although eventually I desire to do so. I h8 starting something only to not be able to finish. Although I gained a fair amount of knowledge about milling in the process, in addition to upgrading the mill for digital position sensor 'scales' and readouts, etc. DROs really improves the repeatability of machined parts.
I have always kept an eye out for a delta design or kit that I could embrace, and the AnyCubic Kossel seemed to match things fairly well. Also their 'kossel linear+' model was so inexpensive, well, while it is a pig-in-a-poke, and if it can't be made to work reasonably well, I felt that it might be useful as a learning aid if for nothing else, and then shit-howdy it was fun to build!! And it only took about four hours to do so. But as DC42 has elucidated in various posts, deltas are tricky and need be fairly precision in all of the areas of fabrication and the AC kossel seems to be a bit short in a few of those areas?! So I suspect (now that I am having to upgrade everything, a peice at a time) that the AC kossel will likely be somewhat fiddly to get running.
Ok, now to your point, yep, the DUET… The AnyCubic TriGorilla controller is a bit like putting in, and powering a battleship with a VW engine. I searched around and found a few of the more powerful 32bit controllers and attendent code oriented for delta control and studied them. Part of the problem with the AnyCubic printer is the company's more or less randomness of their tweaking process to cause the printer to functionally work. Their tuning literature is random at best, while they are working to resolve those matters, there are issues that need be quickly resolved. One is that their version of the Marlin SW which was customized for their two Kossel models only has one template for the first model. The second config.h 'template' file is missing from their github URL and in its place there is an 'apology'. Hah. With these type kit deals, its all about support and AnyCubic is failing in that regard. Experienced 3D delta mechnicians could probably waltz through these type issues fairly easily, but I ain't one of'm and I feel more confident knowing that the designer is experienced and is willing to do a bit of hand-holding if needed. I also bought DC42's Mini-IR Z-Probe autobed sensor. Simple, nicely designed, small with low mass. I machined an aluminum bracket for mine.
The only reasonably well designed controller having both adequate support and documentation is that offered by DC42 and colleagues while the prices for the controller and their available accessories offered on multiple continents is also reasonable. Its a no brainer. So those are my reasons for making the switch. How about you?
