RRF2 to RRF3 and Laser
-
So for the most part I have successfully converted to RRF3. I just completed a print. Now I am trying to get the laser to work as I had with RRF2. I cannot get the Duet to control the laser. What I used to do was have a directory under sys named laser. When I wanted to use the laser I would switch to this directory and run the config.g file in that directory. This is the entry in that file to run the laser using Fan2
; Laser Fan
M106 P2 I-1 ; Disable Fan2 for laser PWM control
M452 P2 R255 F4000 ; switch to laser mode using the FAN-2 output pins to control the laserIn RRF3 I am trying to do it a little differently. First I designated a tool "Laser" in the config.g with this entry:
M563 P2 S"Laser" ;Define tool 2 as laserThen I have a macro to go into Laser mode with this:
; Switch to Laser controlM452 F2 Q4000 ; laser uses Fan2 pin, PWM frequency 4000Hz
It switches to Laser mode ok but does not control it. I cannot turn it on (M3 Sxx ) or turn it off (M5 or M3 S0). It stays on constantly. I also tried inverting Fan2 but it did not make any difference.
I know I am missing something but I don't know what.Thanks

Just to clarify, are you using M505 to switch configs?
https://duet3d.dozuki.com/Wiki/Gcode#Section_M505_Set_configuration_file_folder
Part of the problem is probably
M106 P2 I-1 ; Disable Fan2 for laser PWM controlas the inversion of pins is now controlled by M950 in RRF3. -
I was probably confusing.
I was using M505 in V2 using a sub directory. However I am now trying to accomplish this without using a sub-directory by creating a tool called laser and then using a macro to switch to laser mode. In all this I want to use Fan2 to use the PWM control form 0 to 255. -
Alright, so where is the M950 command to define the pin you want to use?

Unfortunately I'm not familiar enough with laser to say what should or shouldn't work in RRF3 or not.
I'll move this to the general discussion area for some more visibility.

Thanks. I was going to try that today
