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
Hear is my run of the config.g:

4/30/2024, 7:15:35 AM M98 P"0:/sys/config.g"
4/30/2024, 7:15:35 AM Error: in file config.g line 108: variable 'global.flag_FilamentChange' already exists
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.

guywinslow

@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.

To Start a Print
a. Select the filament you want to start with.
b. Run the print file.
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.

@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:

My Setup code in Config.g
DWC code
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.

gloomyandy

@guywinslow It sounds like you are using an SBC based system is that correct? If so login to your SBC using ssh. change directory to where your "virtual sd card" is located (sorry I can't remember the actual path just now). then cd into the sys directory and use grep to search all of the files from M572 and m572 hopefully that will give you some idea of the possible cause of the problem!

achrn

/opt/dsf/sd
so this should do it:

cd /opt/dsf/sd
grep -r -i --exclude=*.json M572 sys macros filaments

will do a recursive case-insensitive search for M572 in those three directories, but not look in json files.

guywinslow

@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.

Phaedrux

Have you updated to firmware 3.5.2?

@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
