@chrishamm Question: I installed DuetPi-arm64.zip and can't seem to login or logon. Has the user or password changed?

@Phaedrux Yes sorry, I don't do this message boards well. It was stabler. Got what I needed to install My SMuFF filament changer. So far only failure point is the Filament cutter. The SMuFF works perfectly. Scripts work without Crashing or giving me error codes not relating to my scripts. I am working on a Filament cutter using two blades from a Wire feed cutter. Had to poll my Direct drive from the Hotend to make room for the cutter. Bummer. But hot end is liter. Futcher add On's to the printer and 8-10 inch screen to the SBC in place of PanelDuo, posable bring back my direct drive extruder.

Note - This is not a Production Printer, just my retirement hobby

@achrn Sory, it took me so long to get back to you. I actually had no M572 commands. I added them into my PETG_Load.g and PLA_Load.g files and the error got consistent enough that the print quit at the next running of one of these files {PETG_Load.g, PLA_Load.g}. I ran your command and back to random error stopping print. About to switch to clipper. I don't have any experience with clipper though.

@guywinslow
Ok, I could not Get rid of the "G1: Axis X is already used by a different motion system" still but did stabilize it so it only happened when returning from "Printing paused for filament change" from the System. So, I put the M400 code in my slicer GCode so it will insert after the M600 command inserted into the print file.

M600
G10 P[current_extruder] R180 ; set standby temperatures for tools
M400

Seems to have gotten riad of it.

Next issue: "Error: M572: Invalid extruder number '1'"

5/2/2024, 7:21:12 AM Printing paused for filament change at X84.1 Y145.9 Z5.2
My Code {
5/2/2024, 7:21:11 AM filament-change end.
5/2/2024, 7:21:11 AM filament-change.g
}
Not my code {
5/2/2024, 7:21:11 AM Resume state saved
5/2/2024, 7:21:00 AM Error: M572: Invalid extruder number '1'
5/2/2024, 7:18:31 AM M24
Printing resumed
5/2/2024, 7:18:30 AM Filament Change Pause
}

this is not happening in my code, so I am Not sure where to look:

1. My Setup code in Config.g
2. DWC code
3. SBC code

I hope this trouble shouting helps someone out there. I have my printer working well enough to print my SMuFF parts now using PLA as the Interface Lyer for my support.

@guywinslow
Ok, 3 of 4 test prints worked ok, Beter then 1 of 2. maybe still and issue. Hear is the scripts i wrote to salve this issue:

Scripts used for Manul filament change.

1. To Start a Print
   a. Select the filament you want to start with.
   b. Run the print file.
2. When the printer sees the M600 command in the Print file it will pause the Print.
   a. Deselect the Tool and the filament will automatically move to the Safe position on the print bed and unload the filament.
   b. Change the filament with the next filament to print with.
   c. Select that tool and the filament will be loaded.
   d. Just hit the resume button after that.

Hear is my run of the config.g:

4/30/2024, 7:15:16 AM Connected to railcore

I would expect this error as it is run after the printer was started. I did a dry run last night (no filament) with my M400 fix. No Errors. going to try test print with 8 manual filament changes.

Minimal test to see if this is going to work.
No MMC setup in Hardware.

I will try and get the run of the M98 P"config.g" tomorrow, but I think I figured it out. I found this note:

M400: Wait for current moves to finish.
Parameters
Sn (RRF 3.5.0 and later only, optional, default 0)
0 = release all axes and extruders owned by the current motion system except for axes/extruders needed by the current tool.
1 = do not release axes or extruders.

If I am reading this write, A axes will not get released right away. Unless a M400 code is encountered. So, calling multiple scripts can get dice. At least as far as the axes the script is manipulating is concerned. In any event sounds good with the error I am getting "G1: Axis X is already used by a different motion system." and the release notes for the RRF 3.5 firmware.

This is probably overkill, but i put M400 at the end of all my scrips. And am going to try a run.

@guywinslow Sorry Raspberry PI 4, and hear is my Bug:
G1: Axis X is already used by a different motion system.

I only have one X, Y and Z System, But Have 5 tools Defined. All Sharing Same Heater and Extruder drive.

Ok, looks like i Can't upload any GCode Scripts or log files. Bummer

Railcore II 300ZL upgraded to Duet 3 6HC with SBC (Raspberry PI 3)
I am Having Issues with the motion system though. I Can't find any bugs in my searches nor any on the combination of hardware. So, I thought this may be a Place to ask questions, Mabe find configuration solutions. So, anyone out there getting random motion system errors?

There isn’t a lot of examples. I just cobbled this together for a temperature tower. It needs to use some Constants from the slicer and variables. I have not been able to get the Latest RRF 3.X working well yet. So, I don’t have variables yet, but hear is a Script that worked for me on layer change for the temperature tower:
;
if move.axes[2].machinePosition > 1.3 && move.axes[2].machinePosition < 1.4
echo "machinePosition=", move.axes[2].machinePosition
echo "Setting tempreture to: 240"
M104 S240
elif move.axes[2].machinePosition > 11.0 && move.axes[2].machinePosition < 11.2
echo "machinePosition=", move.axes[2].machinePosition
echo "Setting tempreture to: 245"
M104 S245
elif move.axes[2].machinePosition = 21.0 && move.axes[2].machinePosition < 21.2
echo "machinePosition=", move.axes[2].machinePosition
echo "Setting tempreture to: 250"
M104 S250
elif move.axes[2].machinePosition = 31.0 && move.axes[2].machinePosition < 31.2
echo "machinePosition=", move.axes[2].machinePosition
echo "Setting tempreture to: 255"
M104 S255
;
Sorry, keeps losing the indents

I have the same issue as demonio669 Today 18:14. I also tried putting the M226 M25 in my print file and the printer went into a pause states and never ran the Pause macro file. Also i could not get anything to operate till i power cycled. This included sending the M24 command after disconnecting the browser and reconnecting the browser to the printer

Figured it out, Extruder issues:

M350 X0 Y0 Z0 E0:0 I0 ; Set microstepping mode

looks like my Stepper motors wont do microstepping mode. If i understand the command right. Symptoms noise steppers, Pore Speed control (Extruder). Switching to latest FW

I installed all three binaries in my printer, and tried a print. Temperature control and fan control a Lot better. But all my stepper motors start and stop now all going in a Strate line. Is there a Configuration change?

Hi, was looking for a Wiring forum. I was having trouble with noise getting into my Ste-per motor signals going to my extrude-rs. the result was printing a circle the extruder would over extrude on a then under extrude. I was able to mitigated to and extent with configuration, but it was still there. When i got my new WIFI board i polled the old Duet controller out of my case and put the DuetWIFI board in. this left me with wires that were tin'd with solder, but no connectors. As i was eager to try the board out i Crimped the connectors on my wires and went to get a new configuration setup for my printer. after fighting the issue stated above, i decided to try and old trick we used to use refer-bushing old equipment, and solder the wire Crimped in the connectors. another trick i used (Old Audio trick) was to twist the wire harness wires before reinstalling them. Walla, problem solved. being and older gentlemen, i was reminded of Murphy's law. Go the extra mile when changing or wiring your printer. It will save some time

The filament would have to have a difference of .75mm to do this.

I went from:
M350 X16 Y16 Z16 E16:16 I1 ; Set microstepping mode, interpolation mode On
to
M350 X16 Y16 Z16 E16:16 I0 ; Set microstepping mode, interpolation mode Off

Second test print cam out OK. looks like its interpolation. Docs on Stepper state it needs a Good Clock pulse. Probably is noise or not up to snuf, it also explanes why its a repeting intervall. Adding to mush plastick then not enuff. All leave interpolation mode switched off

Was ruining another test print. 4mm x 4mm 75mm square. The over extruding started at about 3mm. Looks like its over extruding, then under extruding. Then go's back to normal for 60mm, then it dos it age-an.

Same motors, one is the Y axes, heavy mechanism, it gets slope if there the same. will fix the M350 command. I uploaded the Firmware (dc42/Version 1.16 beta 3). noisy in the steeper motors is gone.

OK, This probably needs to be under the next release of the Firmware (dc42/Version 1.16 beta 2), but i could not find a Blog or forum for it. So hear is the info:

• Ste-per motor noise is down to a Dull rorre (Sounds like a Skipping Hart beet). Its still coming out of extrude motor when i listen to it through a Sc-row driver handle.
  Temperature control, the best i can do with Auto-tune is the hot end doing +- 0.3. it is holding that. at lest for the short print times i have been testing.

Going to let this test print finish to see if it finushes.

Ok, Installed the 1.16 Alfa. The Ste-per motor noise is Still there. I did notes its only on coordinated moves. I can calibrate, move the table around and extrude and all is well. But i run a Print and the noise is there. Note - don't get me wrong this is not machanical, its motor drive control

Ok, i set the pressure advance to this, and started a test print
M572 D0 S0.05 ; Set extruder 0 pressure advance
M572 D1 S0.05 ; Set extruder 1 pressure advance

When i got to the 1.00mm Z height, the Y axes started to jump, as if it was moving, braking, moving, braking. i killed the print as it was getting pretty load and i was afraid it was going to brake the printer.
