Dear all. Sorry about not logging in for some time. Hope the following provides some answers. Napalm. The design of the extrusion feeder without a tension/compression adjusting screw is flawed. The lever arm that provides compression is travel limited. You could a truck spring (metaphorically) as th...

Seems the z axis layer height increases work OK, as seen in the pic, until a certain point. Then it seems to be less than that required as the nozzle is printing the layers and is also pushing the molten filament around. Thus the result seen on the pic.

Thanks for that, but it is not z axis wobble. I eliminated that problem - M8 screws are not constrained at the top. It is the z axis not stepping upwards at the required height - the nozzle just pushes the molten material around during its print that layer mode. For some, extremely unknown reason, t...

Geeetech acrylic I3 Pro B printer. After some experimentation, and wasted filament, finally got my subject printer to do some real stuff - BUT. The but is at approximately 90mm high (Z axis) it longer progresses the required height step. End up with messy print and nozzle definitely within the print...

Seems a previous reply has gone astray. To the nub - the feeder mechanism supplied with the kit has no force adjustment - just a spring. Said spring being redundant as the lever arm it presses against has an end stop. I filed this end stop to try and increase the tension. It worked, sort of. The fee...

Learned - ensure filament is mostly perpendicular to entry hole. Use someones thingy from thingiverse www.thingiverse.com or design your own. Am currently designing a filament holder for both RH and LH sides. In progress. A few nails yet to hit before it is a goer.

OK. Today I totally changed feed rates, etc and repeated print of a design that required small detail - using the 0.2mm nozzle. There were still problems, Basically, the feeder worked OK until there was a need for retraction. In Slic3r this was set at 3mm and 40mm retract speed. I noticed that the m...

OK. Was working OK for a while. Got rid of the Z wobbles - cut away the restraining mounting holes of the top brackets. Got rid of the arcane clips for the glass bes top - double sided self adhesive thermal strips. Added the auto bed levelling advantage using the BLTouch probe. Set aside a morning t...

Changing the firmware codes is not the only solution. Gently removing the wires from the connector and reversing the pole positions works as well. Standard wiring order on the motor is Blue, Space, Green, Red, Space and Black. Change this to Black, Space, Red, Green, Space and Blue.
