Geeetech A30M Purge Bucket & Wipe + Parts

thingiverse

Here is my first version of a Purge bucket for Geeetech A30M. It's made to avoid using Primary Tower and waste big amount of filament. 3 parts to print. It's necessary to move the X axis sensor to let the nozzle going outside the bed area. Remove the Geeetech sticker and replace the original sensor support by the new one. It installs using the existing nuts. Warning: We need to put a 2.9mm spacer between the Z Motor and its support to avoid contact between the motor axis and the sensor. It's necessary to shift the gear by 3mm, to have a good belt alignment. The 'Version 1' of the purge bucket don't have silicone wipe (Version of the picture). The 'Version 2' of the purge bucket need a 2mm thick piece of silicone for the nozzle wipe part; you can use a part of silicone cake pan. Aluminium tape could be put on the bucket. Same silicone piece if needed for the purge wipe version. ------------------------------------------ Purge Wipe was inspired by https://www.thingiverse.com/thing:3372835/comments ------------------------------------------ The cura settings for extruders are: There are also first script version ! They need to be improve (too many stringing). Please, Test, Correct and share them to the community.
