Migration from Maestro to Duet 2 WiFi
-
My printer originally came with the Maestro, now I'm changing to Duet 2 WiFi, @dc42, can you point out the main differences to look for?
-
-
why are you changing? do you have a problem with your maestro?
-
He blew it up in another thread.
-
@phaedrux sorry, I meant configuration wise. Iirc there were some repurposed connections.
-
the resistor for the thermistors is 4.7k
-
You should be able to use your existing config.g apart from the following differences:
- If you have R2200 in your M305 lines, change to R4700.
- Duet WiFi does not support stealthChop, so D3 in M569 won't work
- The way you set a static IP address is different on the WiFi, you can't set it in M552.
- In M350, interpolation only works in x16 mode.
That's all I can think of.

@dc42 wasn't also the z probe hooked up to a different input on the promega?
-
@dc42 oh, and thank you

@phaedrux based on your link, https://duet3d.dozuki.com/Wiki/The_Duet_family_of_motion_control_electronics, apparently i can power my fans externally somehow? I can't find it in the docs.
3 controlled fans, 1 always-on fan connector, voltage selectable between VIN, 5V or external supply in 2
-
There is a fan voltage pin that allows you to input your own voltage line that will power the fans. For example, I use it on my wifi to supply 12v from my 24v PSU through a buck converter.
You'd have to check the maestro diagram to see if it's also there, but if it's similar to the wifi it is in the block of fan connectors.

@phaedrux I don't know what I'm looking for. I see an EXT 5V near the other fan headers. but that's only 5V

Look for VFAN jumper selector
-
@phaedrux yeah, I see those, but it only says VIN or 5V, nothing about external
-
@gnydick it's a jumper. You can either bridged the connection between VIn or 5v, or don't use the jumper and connect your own voltage supply straight to the pin.
Get what I mean?
-
@phaedrux I understand jumpers, what I don't understand is where to connect my own supply.
-
To the center pin.
-
@phaedrux and it can be a single wire from the positive of my 24V power supply?
-
That's right. But if your duet power supply is 24v and you want to power the fans at 24v just use the jumper to connect Vin to vfan.
