Blobdozer (a blobifier mod for Voron 2.4 300)

Since I use the "breeze" auxiliary fan on my Voron 2.4, I couldn't mount the blobifier on the side.

So I came up with another solution that can be mounted on top, doesn't require any "shake," and moves the blobs with a shield. The blobs can be disposed while printing. 

The capacity is around 400 blobs, just like the original. The microswitch for counting the blobs should be used as with the original.

Please use the servo mount and servo housing from the original (Parts are: Mount_voron_2.4.stl, Base.stl, Servo_Arm.stl)

A servo with a metal gear (e.g., MG90S) should be used as the servo.

Dont overtighten the screws on the dozershield! They only need some light resistance for keeping the shield up for disposing the blobs.

The screws required are:

2 x M3*18 (or 20) SHCS (for the shield)

2 x M3/M2 FHCS with a length of approximately 8mm (for the blob lock)

2 x 2 x M3 hammerhead T-nuts

You will need a aluminum strip for the rail with 48*10*0.5mm (1mm might work too but is harder to cut in shape). 

The additional “shield” on the brush holder is completly optional. Sometimes strings with a blob are getting stuck at the brush. The shield might help there a bit. You will need another aluminum strip with 30*10*0.5mm if you want to use it.

Made with tinkercad.

Print it in ABS/ASA with settings for Voron parts. 

No supports needed.

Config

I made the following adjustments to my blobifier.cfg file. However, you must determine these settings yourself after installation, as otherwise you may damage your printer:

variable_purge_x: 33

variable_tray_top: -2.0 #WARNING: USE THE PAPER TEST FOR YOUR OWN VALUE!

variable_purge_start: 0.1

variable_z_raise: 10

variable_enable_shaker: 0
