Installing Duet Maestro in FlashForge Creator Pro (2016)
-
some reprap clone lcd have reversed connectors.
-
You have to use both...
Connect EXP1 to EXP1 and EXP2 to EXP2 -
Well I finally had the guts to try the "clone backwards" issue. And it worked! That is very weird that it worked on the Ramps set up fine but not on the Maestro.
-
So I think I figured out why some of these clone RepRap discount smart graphic controllers have backwards connectors, you see two different connector types, some of these PCB has the marking of a 90 degree bend connector and are fitted with a straight connector which will reverse the pins.

The 12864 display pinout used on the Duet Maestro conforms to the pinout used on the original RepRapDiscount display. The clones of that controller that are widely sold on Amazon and eBay mostly use the same pinout. Sadly, there are some semi-clones that use the reverse connection.

Ok, so this is the homing file that was generated, it is using H1 instead of S1?
what is the deal with that?; homey.g

Thank you for that info!
so now I got an issue where my stepper motors on extruder creating interference to the Thermocouplers. I am looking for some kind of shielding now. but I thought i'll ask what did anyone else do to fix this? which option best or works, shielding thermocoupler wires or stepper motor wires?, or twisted pair wires on stepper motors? -

If you can get shielding or distance between the wires that's even better.
It can also help to ground the motors and printer frame.

I assume your thermocouple wires are already twisted pair.
-
Ok, I made progress. I took the time to pull stepper wires out and twisted each pair, tedious task that needed to be done, Whew! I also lowered the stepper motors amps but, I still had to pull the Thermocoupler wires out of the umbilical cord, as it was still picking up noise, yes it was also twisted. I thought of using shielded Ethernet wire but I don't have anymore crimps left.
Thank you. -
Crimps are readily available in most countries on eBay and Amazon. See https://duet3d.dozuki.com/Wiki/Connector_and_spare_part_numbers. At least one of or distributors (Filastruder) sells a kit of spare connectors.
-
I stalled on this project, looking at finishing it.

If you need any help, feel free to tag me! I just successfully finished my conversion, except for some annoying blobs!

@JadonM Hi, thank you for the post, hmm I didn't get notified and I need to check on that. So another 7 months has past, but I am sitting in front of it now reviewing stuff trying to figure out where I left off. so looks like I need get code setup for priming and do a test print.
-
it's working, printed a 20cm cube, it's so nice to have variable speed part cooling fan!, something the FlashForge Creator Pro couldn't do before , just on/off.
so now I think I want to do the BLTouch tool on this printer next. I do find my nozzle gap differs from middle of print bed to edges, even with the 6.5mm glass, so my smooth rods must not be straight, is this what the BLTouch can help with?
-
@Fireflynj said in Installing Duet Maestro in FlashForge Creator Pro (2016):
, is this what the BLTouch can help with?
Yes if you use mesh compensation to create a heightmap of the bed.
-
Cool! Ok, will be doing the BLTouch then, Thank you @Phaedrux .
I saw @JadonM did a new graphical display menu

with external SD card access, awesome! Thank you!I need to update the firmware first , ran M115 to see:
FIRMWARE_NAME: RepRapFirmware for Duet 2 Maestro FIRMWARE_VERSION: 2.04 ELECTRONICS: Duet Maestro 1.0 FIRMWARE_DATE: 2019-11-01b1 -
@dc42
I am a little nervous doing this, I'm reading up on updating firmware and document says to make sure I have correct firmware, I understand I need to do 3.0.0 first before I get 3.1.1
https://github.com/Duet3D/RepRapFirmware/releases/tag/3.0but I don't see anywhere saying that this firmware is for Duet 2 Maestro.
can you confirm?Thank you.
