Multiple motion system

[Alva]

@dc42 I have edited the code and logic a bit. Found different cases:

; 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

test_2nd_MS.gcode
.
This happened when i activated the daemon before the move to X0 Y0. But if i activate the daemon after that then it works perfectly. Cannot relate whats going on.

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

@Alva Looks like it is a timing problem or something.

[dc42]

@Alva thanks, I will try to replicate it.

[Alva]

@dc42 Thank you

[dc42]

@Alva I have reproduced this and I am looking into it.

[dc42]

@Alva I created https://github.com/Duet3D/RepRapFirmware/issues/1064 and I am testing a fix.

dc42 created this issue in Duet3D/RepRapFirmware

closed Use of multiple motion systems causes Code 3 halts in 3.6 beta1 and beta2 releases #1064

[dc42]

@Alva please try the new Duet 3 Mini firmware binary at https://www.dropbox.com/scl/fo/pasag1g18orahwvn49qp2/ABWgw6D-TyKWxxurTmGwiUE?rlkey=r9h3rjyw1l4wh7xbr8yho37gw&dl=0.

@dc42 It seems to be working. I have tried all the above conditions and works as intended. Can i expect the same fix for Duet3 6HC board as well, as i observed the same behavior in it as well. Thank you

[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

@droftarts thank you. got it.

@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.
