Finished assembling an Acrylic prusa Geeetech I3, I have the prusa Geeetch Aluminium frame type,?
this Acrylic should be sold next month, the customer wanted a fully assembled printer that was functional.
The Geeetech kit price of €135 , free shipping from Germany to Spain, all parts correct and?
assembly very easy, a good deal for begginers into 3D printing.
Test printed a 2 x scale Benchy, before the happy burger holders, all seemed OK.
The new GT 2560 board has many new print options. very nice indeed.
I use 4 x corner heater bed Delrin blocks and not the as standard screws with springs.
Also use a modified Dial indicator to chech level that slots onto the X axis rail.
This allows easy bed levelling by shimming if necessary the blocks on the 4 corners and also
allows for synching the 2 x Z axis screws.
Also I use a .15 mm bras shim for nozzle to bed adjustment,lastly I opt for phosphor bronze nozzle heaters which are?
easy to make. my personal choice, as I find the aluminiun heaters radiant to much heat away from the nozzle.
The fan blower holder I desined and printed allows for 2 x fans, air blows along the legs either side of the heater block, the cross mounted fan?
blows arir downwards through holes in the base of the holder.
Actual fans holder just clips onto the end of the extruder stepper motor body.
Hope of interest.
