Material Endstop False Detection

I am experiencing a very annoying issue with my M200 Plus bought in september.
Lately the printer as started to automatically pause because the printer falsely detects no material in the endstop, even if material is correctly loaded. I just have to resume the print, but it’s a waste of time considering that i print mostly overnight.
This is very annoying, the material endstop isn’t a consumable part and should work properly with no fails, especially in a printer that’s only 5 months old.

Is there any solutions to the problem? How should I proceed?

The filament end detector of your M200 Plus is damaged.
I had the same problem and I had to replace that component.
Open a support ticket with Zortrax and if your printer is covered by warranty they will send you a new material end detector.

Hello,

Please contact the reseller from whom you purchased the device and ask for a spare material endstop. If they do not have the part in stock - let us know via support form.

Check to see if the filament has worn its own path. I filled this with super glue and haven’t had a problem since

Hi Karolina,
I have the same problem with my m200 plus. Can I get the 3d design of the endstop detector somewhere so I can print a new one ? I could just transfer the electronics.
Kind regards,
Rob

Hello Rob,

not a problem - please find attached requested .stl files.

I have had the same problem on both our M200 plus and M300 Dual - the filament digs a groove in the 3D printed housing, meaning the sensor starts to incorrectly think that the material has run out. I’m surprised this was not fixed between the release of these two printers since I’ve seen it very consistently!

To fix the problem on our machines, I added an aluminium block into the material switch so that it does not grind down over time:

Hello Tom,

thank you for sharing your solution - this is a great idea.

Hi
Regardless of settings my printer ignores this sensor. The LED is always on blue, but I’ve done filament tests through it and it ignores them.

Hello Mark,

if the printer determines there is no material in the even if its detection has been turned off - there might be a problem with the LCD display through boad (to which the endstop is connected) or motherboard itself.

Hello
Says it’s material even when it’s gone
