Hello, I have installed on my Sovol Sv04 the firmware version 1.15.25 from Bjoern on the Printer and on the Display the 1.15.2, because it shows me on the printer infos that this is the supported version.
So a just wanted to start a print but it does not work. When I want to start, the printer heats up, goes on the X and Y axis home. Now he waits until the printer is fully heat up and now there is the problem: I retreacts the filament out of the head and starts to peep, now on the display appears a dialog box where i can choose between “Resum the Print” and “Stop the Print”.
I do not know why this happens with every Filament-, Print- and Printersettings. I normaly work with Prusasclicer, currently with 2.9.2. But i also tryed Cura and the Sovol Cura but nothing works. With the original Firmware it worked everthing fine.
This is my selfmade Start-GCode, maybe there is a mistake. This one is for the Singel Left extruder.
Is this on a Sovol SV04 ?? If so, I don’t understand why you have the M280 command in Start G-code. That command is used to set the position of a servo, often used for a non-standard ABL probe. Also, I don’t know why people use a “prime line” in the Start G-code. My experience is it does nothing but leave a permanent mark along the edge of the bed.
Which will allow you to view the serial terminal and get lots more information. Down side is it requires a constant USB connection PC to printer. Once you debug you can go back to SD card prints.
The more elegant solution is Octoprint. It will run on any PC. I use an old laptop with a busted screen. There is also an Andriod version but keeping the phone charged while the USB port is connected to the printer is a non-trivial task.
Hello MPohl & welcome to the forum!
According to your problem description your SV04 is just missing filament in the filament sensors. You could either insert short pieces of filament in each sensor or simply disconnect the sensor plugs in order to skip this problem.
Your custom start sequence seems OK. M280 P0 S260 will just reset your CR-touch sensor.
Thank you, I checked all pins from the Filament sensors all ok. And filament was also in. Now I found a solution, I just wrote M412 S0 in my Code and now it works fine!
I still won’t use !! I purge the filament when I change it, and usually do 2 - 3 loops around a part just before it prints. This way, you can see how the first layer is laying down.
