I think i have the same problem, my stall protection shows 0.7A its extruding, but very very slow.. also my barrel was not straight but while testing without pellets the barrel turned a bit so the opening for the pellets and hopper is now turned 45degrees clockwise and now it seems straight.. also no click for me at the cv pot.. how did you fix getting more A on the stall protection? hopefully it also extrudes a bit quicker then.. thanks!

The value shown on the stall protection board is the amount of current the motor is consuming at that time. It is not an allowed value or set value or limit.

The proper way of checking the current limit is to use a dummy load, for instance the included heater, as described in the instructions.

But other than that, it sounds like you did everything fine and are ready for extrusion. I'd say there's no need to re-do the stall protection test with the heater, just that it isn't good practice to do it the way you originally did.

After raised the CC to 1.7A, when the motor turned, I did not see the BLUE LED flashes once in a while.
Am I ready to do some plastic extrusion?  But I still want to know the meaning of CHSRG and FULL.  Thanks.

Then I followed the meter method, disconnect the motor leads from terminal, connected the AMP meter between - and +, the current reading was 1.9A, so I adjusted CC pot CCW to reach 1.5A.  But once in a while I can see the Blue LED(CHSRH) flashes quickly when the motor turns.  Does this means I reach the maximum current of 1.5A?  But the current reading was about 0.49A on the display of Stall Protection Board, and the motor is only driving the auger without any load.  What should I do?  Should I adjust to 1.7A using meter adjustment method?  Can you also explain these 3 LEDs - CC/Cv, CHSRG and FULL?  FULL LED stays on Green, never seen CC/CV came on.  Thanks for your inputs.http://soliforum.com/i/?W9R2EVD.jpg

With everything connected-motor is turning and heater is running, what should the stall protection board readout in auto, my readout is showing 12.4U, 11.5U, 0.38A and 4.3P.  Without the motor connected, the current is showing 0A and 0P.
I tried to follow the instruction, I do not hear the click on CC pot, I can hear the click on CV pot.  So I turned CCW on CC pot many turns to make sure it was minimum, then turned CW 7 turns.
Please help!
