I fitted my 3d pile of bits together today and mounted the head on my CNC table but the results were less than useful?
I can't seem to get any material extruded, well practically none anyway.
Its just slipping the feed rollers, even with a hefty push by hand on the filament while the motor is jogging produces nothing more than a tiny blip every minute or so, you can feel the motor trying to feed.
I was expecting to see a thin thread extrude but not so.
I have tried raising the hotend temperature all the way to 250c but no change really.
The head is a 0.3mm one and i have uprated the motor as my drivers only go as low as 1.5A and the supplied motor was only 0.84A.
I calibrated the A axis by removing the hot end and feeding filament then measuring it etc that seemed the right way to set it?
I have speed in Mach3 set to 100 and acceleration to 20 i think.
The code seems to run fine at least.
Have i started out with a bad head or too small a nozzle for PLA??
Any suggestions?
This is the head BTW...
