Im using Cura Gcode post processing extension to insert a pause at a particular layer.
The printer moves to the location I ask it to but then either returns and resumes printing imediately or stops and wont restart. The LCD often locks with the inability to Stop/Pause/Resume and the only action I can do is power off.
The function works properly on my Ender, where Im prompted correctly to resume/purge etc.
I see @Janet and @Arthuru raised the same issue for other printers but no response.
Using John Carlson firmware.
@Bjoern Does your firmware fix this problem? I see your commit has “Fixed print mode hickup when pausing / resuming.”
Edit #1 Swapped to @Bjoern firmware and still not working.
Edit #2: Whilst the printer recognises the M0 command, it doesnt seem to correctly process what Im guess should be the M108 command (LCD screen press).
There are inconsistent results when issuing these commands manually through, e.g, Pronterface.
The M108 does seem to move the printer from “paused for user” but the print still doesnt continue.
My current firmware SV04-IDEX-3D-Printer-Mainboard-Source-code-v1.1.B3.9 should be able to handle the g-code instruction M25 to pause SD print properly. If not upload the particular part of your print file here.
The current implementation of M108 requires an external host. It will not work using the SV04 display.
Thanks – I was working my way through the different M code options in the Pause extension and have just got to your M25 suggestion.
This has some functionality in that the screen displays instructions and graphics to change filament, but asks to clicks “Yes to continue or”.
There is no Yes button, but there is a Print button and Stop, neither which do anything.
After a long pause, another screen appears that asks to “Click Yes to heat and change….or No to stop print”. There are Yes and No buttons now, but neither do anything and I have to power cycle again. At this stage, serial output from Pronterface says “paused for user”.
Just to rule out a possible mistake: Your current display software version is SV04-Touchscreen-v1.1.B3.6?
Upload the particular part of your print file & let me know which print mode you selected.
Thanks - Im actually using v1.1.B3.7 and 1.1.B3…9.S(izzle) so assuming later version is ok?

If anyone is interested, the Pause command does seem to be honoured by the printer - its the LCD that is the problem - lack of support?
If I connect to Octoprint, the Pause command is prompted, and I can click OK to unpause.
I notice that the LCD, when displaying messages, often has a + + symbol implying more messages which cant be opened.
Nor does scrolling seem to work, e.g trying to show layer numbers on a large filename.
Swapped to @Bjoern firmware and still not working.
