3 color printer with 3 laser filament sensors

[zendesigner]

HI I'm having following issue/question.

I'm working on a large 3 color corexy printer. It has 4 steppers for movement (x,y,z1, z2) and corresponding microswitches endstops (x, y, Z, E0 for Z2) . Now i have 3 steppers for extruders with 3 laser filament sensors.

I have a duet 2 wifi + duex 5 were i'm using the duet5x for the extruder steppers (e2,e3,e4) and wanted to use the corresponding endstops on the duex 5.

Now i read in this forum that laser filament sensors can't be used on the duex 5 due to a limitation in the board.

So my question is now how do i fix this ?

Can i place the movement steppers and endstops on the DUEX 5, and the extruders and filament sensors on the duet 2 ? so complete reversed from my original approach.
And if so how you configure this then in the software ?

Or are there better ways to get the 3 filament sensors working on duex 5 ?

Cheers
Bart

That's probably the best way. In the config file you should need to change the stepper driver assignments in M584 and the endstop configuration in M574.

Are you using RRF2 or RRF3?

Yes, if you are running RRF3. You don't need to change the stepper motor connections, only the endstop connections.

It is also possible to connect two filament monitors to the CONN_LCD port.

hi ,

Thanks for the help. I'm using an RRF2 board still from an older printer.

Will let you know how it went

Hi,

I got the boards working now and switched around the X,Y,Z1,Z0 to the duex5 and the E0, E1, E2 on the Duet wifi 2 i'm running RRF3.2 now.

Now i'm getting cofused with choosing the right drives and endstops in the RRF tool. And that compared to the wiring diagrams of both the duet2 and the duex5.
The tool shows different endstop names as the wiring diagram , and has 2 X,Y,Z driver letter assignments. When you add the duex5 as a board it adds choice boxes same as the original ones.

Is there a pinout list of names anywhere, so i can clearly change it in the config.g later?

There is a list of pin names here https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Pin_names_for_Duet_2_WiFi_Ethernet.

seems i have a wiring issue. compared it with my other printers
