Duet2 Beginner with RRF Config Tool

printerdad

Ok here are some questions I have. Sorry if this info is readily available somewhere.

Duet 2 Ethernet - firmware 2.03 to 2.05

I am using 2 Z motors on headers ZA and ZB. Do I double the value for amps of the motor when I input the rated z amperage?
I have my BLtouch as a z-probe wired like this:
BLTouch-------to------Duet
out (white) --- Zprobe header, input
GND (black) --- Zprobe header, GND
+5V (red) --- Expansion, +5v (pin1.)
Control (yellow) --- Expansion, Heater3 (pin 8.)
GND (brown) --- Expansion, GND (pin 2.)
Is this a typical configuration, and if so, do I set the servo control to E3 Channel?
For my fans, I have 2 extruders, each with their own heatsink fan. I also have a parts-cooling fan. I set the extruder fans for no thermostatic control, so they would be on all the time, wired to the non-pwm fan headers. I set the parts-cooling fan to no thermostatic control so my slicer can control it, wired to pwm control. Will those configurations operate my fans as intended?
How do I add a 3rd always-on fan for the duet board cooling? Possibly wire the two extruder, always-on fans in parallel?
I am not sure how to configure my tool. I currently have a single Tool 0, set with extruders E0 and E1, heaters E0 and E1, and fans 1 and 2. Is this a typical configuration?
Is there a spot to input the x-offset for the space between my two extruder nozzles?

Thanks for your time and advice, Dad

They are wired in series internally, so you just need to set the current to whatever 60-85% of the rated max current of the motors would be and you're good to go. Same as if it's a single motor.

Confusingly it should be E2 Channel in the config tool. That frees up Heater pin 3. It makes a lot more sense in RRF3 because it lets you assign actual pin names.

Duet 2 Ethernet - firmware 2.03 to 2.05

Why not update to RRF3? The config tool gets a bit more logical with RRF3 because of how flexible it is to use pins. If this is a start from scratch kind of situation, this might be a good way to go.

For example, with RRF3 you get to choose your pin mappings like so

If you want your heat sink fans to be always on you don't have to specify them at all in the config tool or your config. Just connect them to an always on port in parallel or individually or directly to VIN. Whatever you like.

For the part cooling fan connect to fan0 and fan1 and assign those fans to the tools.

@printerdad said in Duet2 Beginner with RRF Config Tool:

How do I add a 3rd always-on fan for the duet board cooling? Possibly wire the two extruder, always-on fans in parallel?

Yes that's an option if you want to have it always on. Or connect it to Fan2 and set it to thermostatic and have it tied to the bed heater and extruder heaters at 45c so that it comes on during a print.

If you have 2 extruders you'll need 2 tools.

@printerdad said in Duet2 Beginner with RRF Config Tool:

Yes that's on the tools page as well. There's an edit button under the heading of XYZ offsets.

If you do wish to update the firmware to RRF3 and start with a fresh config from the tool here's how.

If you still have access to DWC. Upload these 3 zip files, one at a time in the system tab. Don't extract them. Reboot after each. Use M115 to verify the firmware has been applied.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/Duet2and3Firmware-3.2.2.zip
That will get your firmware and DWC up to date.

For your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.

Here's a config.json file you can load into the config tool to play around with that is set to use RRF3 and has 2 tools and a BLtouch configured.

I didn't know some details for your printer so I left them default, so you'd need to change the details to suit.

This is a ton of great information, thank you. I do want to update to RRF3 however I have a cpl more questions.

If you still have access to DWC. Upload these 3 zip files, one at a time in the system tab. Don't extract them. Reboot after each. Use M115 to verify the firmware has been applied.

I dont know IF I still have access or not...I have never turned this board on before to be honest. It's straight from the box. I can connect it to my pc via usb but getting the ethernet to work will be a nightmare because my roommate, who is a software engineer for our ISP, has an overly complicated network setup in our house, and I dont want to hear him crying right now.
Can I simply connect the board via usb and have access to DWC?

You can't access DWC over USB

You could however connect directly over ethernet from your PC/Laptop

This may help

https://duet3d.dozuki.com/Guide/1.)+Getting+Connected+to+your+Duet/7

The board will use DHCP by default so it shouldn't be too difficult to connect to any network that will serve an IP address.

If not, the direct connect method described by @jay_s_uk can be useful.

printerdad

so much great info, thanks guys. I have a lot of tinkering to do now!

Here's a config.json file you can load into the config tool to play around with that is set to use RRF3 and has 2 tools and a BLtouch configured.

How do I use this file?

@printerdad

nvm i copied and pasted into a new .json

Phaedrux

Should have been able to download it and then upload it into the config tool. If it was opening as a text file in a browser window file > save as.. probably would do it.

printerdad

New questions, I need help with the config tool again. I am setting up my fans, and i want my extruder fans to turn on only when the extruder is heating.
Do I

Fan0 set to thermostatic control, yes. Monitor E0, threshold 45C?
or
Fan0 set to thermostatic control, no. Under tools page, select fan0 for the E0's fan?

whats the difference? It wont let me assign fan0 to any E in tools, if I have thermostatic control turned on for that fan0.

Also, I assume the extruder XYZ offsets are the distance away from 0,0,0, when the printer is homed to XYZ? Why would there be a Z offset?

thanks, Dad

Phaedrux

Did the config I provided not have all the fans assigned as well? Should have been fan0 as the part cooling fan for tool0 and fan1 as the part cooling fan for tool1. And fan2 as the heatsink fan tied to the heaters.

@printerdad said in Duet2 Beginner with RRF Config Tool:

Yes, usually tool0 would be 0,0,0 and tool1 would have an offset in XYZ from there. There is Z because the tools aren't always are the same height.

printerdad

This is my fan setup:
fan0, heatsink E0
fan1, heatsink E1
fan 2, parts cooling fan for both

In which case your fan and tool section in config.g would look like this

Ok Ive got 3.2.2 installed with the new configuration files, installed using dwc. Here are a couple problems Im having.

ToolFan and Fan2 are both operating the same fan, which should be Fan2.

Fan2 starts at 100% upon power on, which should be 0.

Not sure why ToolFan is even listed as it has thermostatic control. (I have 2 tool fans)

Screenshot same.png

Also, Tool0 starts as active upon power on, but tool1 does not. Seems odd.

Screenshot active.png

This is a screenshot of my config.

Capture gcode.PNG

Thanks guys, Dad

Phaedrux

TOOL FAN and FAN2 are the same thing in your case.

TOOL FAN will control the fan of the currently selected tool. IF you had multiple tools with separate fans, you would see TOOL FAN, FAN1 and FAN2 (as an example). Tool fan would control either fan1 or fan2 depending on which tool was selected at the time.

If you wish you can hide the fans you don't want to see by clicking on the change visibility button.

M950 F2 C"fan2" Q500                               ; create fan 2 on pin fan2 and set its frequency
M106 P2 S1 H-1

To have fan2 start off, change the S value in the M106 command from S1 (on) to S0 (off). Like so:
M106 P2 S1 H-1 to M106 P2 S0 H-1

Tool0 starts as active at power up because there is likely a T0 at the end of your config.g to select the first tool. You can only use a single tool at a time, the others will be in standby or inactive. It would be up to your slicer to send the tool change commands to switch between them as needed.

printerdad

I do have 2 tool fans though, fan0 and fan1. I have two extruders each with their own heat sink fans. Fan2 is a parts cooling fan, not a tool fan.
The fan slider is operating my parts cooling fan.

Also, If S0 or S1 is the command for fan start on/off then why is only one fan starting on, when two of them have S1 in the gcode?

Phaedrux

There is some confusion on terminology here.

Fan0 and Fan1 are the heatsink fans, correct. They are thermostatically controlled for each heater.

Fan2 is the parts cooling fan, also called tool fan. Same thing.

The fan0 and fan1 will only start at full power when the temperature is reached. They are off until then.

printerdad

i see, I assumed the heatsink fans were tool fans considering they are attached to the tools.

Phaedrux

Tool fan because it's a fan controlled for the tools operation, ie cooling the part. Or maybe clearing chips away. Or maybe it's not even a fan at all.

The heat sink fan is controlled by the heater, not the tool directly. Though in this case the heater is assigned to the tool.

The M563 command defines the tool. Which tool number it is, what extruder drive it gets, which heater, which fan.
