After roughly 1.5 YEARS after buying one of these snapmakers I finally got my 350 printer. I have to say I was impressed with the quality of the boxing, what came with it and the instructions. That said, I assembled everything and eagerly sought out a first print, loaded the filament to do my first print.
That has all come to a crashing end, I am no longer impressed. Because I cannot print a single thing. I currently have an expensive fancy looking paperweight and several feet of melted filament in the shape of failed prints laying around.
I get āFilament reloadā warning and the system stops CONSTANTLY! I havenāt been able to go longer than 20mins of printing without an error. To say I am agitated is an understatement.
Not to be a total noob, I have done some homework before coming here. I found instructions related to this issue and directions on how ācorrectā this: It says to download pronterface, connected to the printer via the usb cable, entered the command āM412 S0ā to turn off the filament sensor (says the command was accepted), connected through the software (used both snapmakerjs and snapmaker luban), uploaded a file to the printer. Start the print and itāll go for a little while then suddenly Iāll notice no sound. It stopped. Iāll take what oozed out of the head, and restart. Few minuets later. I STILL GET THE ERROR! Even after turning off the filament sensor. WTH? I am on the verge of tearing into it and soldering that microswitch closed, but if the filament switch is supposedly āturned offā in the software what will doing that accomplishā¦
Stop me from destroying this thingā¦
EDIT: It stoppedā¦ againā¦ and I ran the command codesā¦ againā¦ and restarted itā¦ againā¦ Hereās an image of the command script. (towards the bottom is where I unplugged it from my computer)
Did you save your code entry by M500?
If you want to, you could simply disconnect the filament switch from the print head pcb.
I had a loose contact at the connector which caused no runoutĀ“s anymore.
Iām not sure M412 is a value written to the firmware, so M500, while always a good idea, may not help here.
I double checked in the firmware that M412 is enabled and it looks like it is, so itās weird itās not acting like expected.
Only other thing I can think would be take the right side cover off, remove the 2 fan mount screws from the rear of the toolhead, and check the microswitch mount screws didnāt loosen in transit, that has been an issue a couple people have had.
Thanks. I restarted it again in the morning. I ran the M500 code, let it rip and left for work. Hopefully itāll still be going when I get home.
Itās entirely possible that Iām doing something wrong. Mechanically and a esthetically itās absolutely beautiful. Once I get this issue straightened out I have no question it will be great. Some other printers come with 3d printed parts that looks like it was printed on a potato. Not a single 3d printed component in sight, which for me was the primary selling point.
Well, Iām excited. It was still going after roughly 8 hrs of nonstop printing. Hearing that almost rhythmic digitalized like music of the motors working in unison at the door was a pleasant to say the least. And the print looks great so far. I donāt want to jinx myself but it seems the issue is at least temporarily resolved until I can get the printer head filament sensor corrected / fixed. Hereās hoping.
Alright. Iām trying my second print and now it will not let me past filament out screen. I tap start to start the print and it just goes straight to the load filament screen, wait for it to heat up, load the filament thatās already in there, waste some filament as it just oozes it out, click continue, tap start, right back to filament out screen. I removed the filament and reloaded it. Same issue. I cannot find how to fix this.
Iām beginning to be come disillusioned with this deviceā¦
Thatās unfortunate that issue is coming back. However it is somewhat fortunate itās a fairly straightforward mechanism - just a single microswitch that checks the filament.
I donāt think youāll be able to do much without taking the right cover off. Have you checked if the filament check switch is screwed down securely? It should only take about 10 minutes to disassemble and check, itās quite a good design for the toolhead.
