Flashforge Creator Pro & Duet 3 Mini 5+
-
This is my first post, so please be gentle.
I have an old Flashforge Creator Pro that has been great to me for 6000+ hours of printing but is starting to show its age.
Looking at upgrade or replacement options there isn't a lot of parts or information available on them. I am looking to upgrade the creator pro with a duet board based on lots of recommendations from here, google and Reddit.
That said, I've seen some posts of people doing this with the Duet 2 but see that the Duet 3 is out and it has compatibility with Raspberry Pi and the 7" display. Since I already have lots of pis and a screen available I was thinking of going this route. However, I don't see much information on other people doing this so am just looking for a yea based on the equipment on the pro, it should work fine with the Duet 3 mini 5+ and has the correct functionality to make it work.
I would appreciate any advice the community might have. I am a bit of a noob in this area but have decent fundamentals, am relentless to figure things out, and am good at reading lol.
Thanks in advance!

Well I ordered a board. I will try and document the process in another thread and potentially link back here incase anyone is interested.

Let us know if you have any questions on specifics.
-
So I got the board the other day and I am working through the documentation and I have a few questions:
-
Can I use the pi to power the duet board? If see that there is a 5V select jumper but I don't see much information on it regarding the Duet 3 Mini. In the documentation, it just says that you need to supply power to the pi and duet board and that the duet board cant power the pi but it looks like vice versa is possible. The board however did not power up with just the ribbon connection from the pi. What are the current requirements for the Duet board?

I have a duet thermocouple daughter board on order but it was definitely not as easy to source as the main boards. Is there a reason that the Duet boards don't have support for thermocouples out of the box? Is this thermistors only? Is there a benefit to using thermistors vs. thermocouples? I am wondering if I should just figure out how to convert my printer to use thermistors vs. thermocouples.

I bought a DC42 IR probe that only required 3.3V, GND and an io.in. In the RRF config tool under Z-probe I can only use the temp connectors or io3? I am bit confused by this since the temp connectors are only 2 wire and the io3 is a waste of a 5 wire connection when you only need 3 wires? I am missing something? Also, I am assuming I don't need to do anything with the Modulation Pin or PWN Control Channel in RRF?
Thanks in advance!

There's no point; if you want to use the stepper drivers, fans and heaters, you'll need to connect a 12-24V PSU anyway. Then use the onboard 5V to power the Duet. If you really want to power the Duet from the RPi, you could power it via USB.

Adding the circuitry directly to the Duet mainboard would add cost and increase price, for something that relatively few people need.- I bought a DC42 IR probe that only required 3.3V, GND and an io.in.

My IR probe is connected to io3 on my Mini 5+. io3 is the only analog IO input; see https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mini_5+_Hardware_Overview#io-headers
In the past on Duet 2, the IR probe worked in analog mode, but on Duet 3 it is set up in digital mode in the configuration. So it may be that this limitation is no longer valid; I honestly just haven't tried it any other way, as I have spare IO anyway. I'd say set it up on io3 and make sure it works, then try it on another IO header. No, you don't need modulation or PWM control with the IR probe.
I'm not sure what this has to do with the temperature input; those inputs have special circuitry (a voltage divider) designed for reading the resistance of a thermistor or PT1000. You can't connect a probe to that. Also, the io3.out and 5V pin on io3 will still be available, just a bit harder to get at.Ian

So I am well on my way to getting the machine set-up but have run into an issue with one of my end stops that I can seem to figure out.
I have been working through the commissioning steps and am stuck at the end-stop portion. My X and Z end stops appear to function correctly during homing but I noticed some odd issues when the machine hit the Y-axis end-stop first. In testing the end stops with the M119 gcode I noted that the X and Z endstops register correctly via M119 but not the Y-axis stop. When the Y-axis stop is depressed, the machine registers that all three endstops are hit. Once removed, all end-stops register as not touched. I've went over my config a few times and changed IO ports but cannot get it sorted. Another thing I noticed during this testing is that the LED's on the end stops on the X and Z axes illuminate when pressed but the Y end-stop does not. I checked the wiring on the Y axis and even re-crimped the connectors.
My current config.g is below. Any advice or help is very much appreciated!

All my attempts ended with either nothing happening or a manifest error.
Secondly, my stepper motors are a bit noisy under certain conditions. The symptoms are below:
- The X and Y-axis steppers sound pretty good when moving.
- As soon as I do any movements and the steppers stop moving I have a nasty hum/whining during idle.
- When the Z axis is moving it sounds horrible kind of like a soft grinding.
The steppers are configured based on other people's configs for the same printer (Flashforge Creator Pro).
I am looking for some advice on tuning these steppers better.
Thanks in advance!

Is the Y endstop physically the same as the X and Z endstop? Are you sure it's wired correctly? Can you show some photos or show a diagram of how it's wired? If triggering Y makes all seem triggered maybe there is a short?
For the stepper tuning, see here: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_tuning
You may be able to improve the noise by setting up stealthchop.

@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.
