Multiple motion system

[dc42]

@Alva I have just put a 6HC build at the same location.

[Alva]

@dc42 Thank you , I will check it out

[T3P3Tony]

@Alva please can you confirm if you have tested this.

[Alva]

@T3P3Tony Hello sorry, i haven't checked it out. The 6HC board i have is bit different from the original version. So i need to build it differently. I am actually waiting for the beta 3 version of the firmware now.

[dc42]

@Alva you could try 3.6.0-beta.2+5 at https://www.dropbox.com/scl/fo/1l1t3h52jkapaszdpcruz/AOWakD9qTwZ2HRnV7N3vVvQ?rlkey=42ehcpbas7rwgz6z1318mbceh&dl=0 if you like. Use it with care because the changes in it are quite substantial. You may wish to reduce motors currents until you are happy that it behaves correctly. See https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-Beta#reprapfirmware-360-beta3-in-preparation for important changes.

[Alva]

@dc42 Thank you. I will try it out and let you know the status.

[Alva]

@dc42 g binary "0:/firmware/Duet3_SDiap32_MB6HC.bin" not found , in the drop box this file is not available

[droftarts]

@Alva Get the "Duet3_SDiap32_MB6HC.bin" file individually from here: https://github.com/Duet3D/RepRapFirmware/releases/tag/3.5.1
Otherwise it's in the zip file download in most releases, eg in "Duet2and3Firmware-3.5.4.zip" here https://github.com/Duet3D/RepRapFirmware/releases/tag/3.5.4

@Alva Tested the second motion system with the new version 3.6.0.beta2 + 5, but i am getting the error shows in the picture below:

tried gcode :

set global.daemonStop = true ; stopped the daemon
M118 S{"starting to move"}
G90
set global.daemonStop = false ; activated the daemon which only use U axis
G1 X0 Y0
M400 S1
G91
G1 X100 Y100 F200
M400 S1
G90
M118 S{"move done"}
M99

daemon.g :

; File Name: 		/sys/daemon.g
if(!exists(global.daemonStop))
	global daemonStop = false	; Set to 1 to stop the daemon.g, it can be use to upload a new daemon.g file

while( global.daemonStop == false )
    if(state.status== "processing")
        G91
        M596 P1
        G1 U5 F300      
        M596
    G4 P0
M99; Exit; File Name: 		/sys/daemon.g

@Alva U axis was trying to use only in the second motion system. so motion system 0 and motion system 1 are not able to execute simultaneously.

[Alva]

@Alva i have tried the same with the 3.6.0.beta2 +3 it worked as intended

[Alva]

[droftarts]

@Alva We're going to release 3.6.0-beta.3 in a couple of days, please retest when we release that.

Ian

[Alva]

@droftarts Sure will do. Thank you.

[T3P3Tony]

@Alva it's released:

Testing is appreciated

My understanding of the dual gcode stream is: you can open two gcode files at the same time and have a daemon.g running in the background?
At the same time you'd have to split the config.g into two portions.
Maybe put the U-axis specific lines in the startcode of the second stream?

[Alva]

@T3P3Tony Tested the above mentioned testing procedure and got the same error as 3.6.0.beta2 + 5.

[Alva]

@o_lampe My requirement is to utilize the unused axes during printing, with their movement controlled via daemon.g and triggered by a flag. My understanding of multiple motion systems is that the unused axes should be accessible to the other motion system. However, the error I am encountering indicates that the unused axes are still being treated as part of the motion system responsible for the print job.

[Alva]

Any updates about this topic? My observation is 3.6.0-beta2+3 worked , but after that it is broken. Thank you
