I just purchased a Geeetech A10 a few days ago, using PETG 1.75mm filament.
I am getting it dialed in fairly well, but do notice that my extruder teeth keep skipping in certain parts of the print.
-adjusting the tension spring
-slowing down my print to 80%
-heating up the nozzle an extra 10 degree Celsius for filament to flow easier
None of these settings made a noticeable difference, the gears still skip in certain parts of the print... it is frustrating. I am using a .6 nozzle.
It is not over/ under extruding, flow seems good until it skips in certain parts, nozzle and printer are basically brand new.
So I am wondering how can I up the current flow to the stepper motor of the extruder to give it more torque?
Would be good to get some advice and to know how to meassure stepper engine current.
@jarda3d what do you mean with "extruder case" ? My extruder has no case... I don´t know any extruder with case... please, clarify.
You really need to apply bigger current to extruder stepper motor, but...
A10 stepper is easy to overheat if you print with ABS. Measuring of temperature is easy: If you put your hand to extruder and you have no problem to hold it more than 10 seconds, then it is cold. If you cannot hold hand of someone else on the extruder, then it is hot.
For adjusting current, search here for A10 howto, it is easy to do it with little screw and voltmeter with about 2V range.
Metal feeder assembly? Like an aluminium one?
I have been playing more with temperatures, feed rates, speed, fan speeds... Sometimes it works better, tho it still will skip in most prints at one point.
How do I up the voltage to the feeder? I took the power housing apart but can not located a POT to up the current on this motherboard... I checked overall voltage to the board and it read 24.2V, its a 24V board.
My feeder motor is barely luke warm after a 12 Hour print... I need more torque on this thing. How to please?
Now how do I adjust the E driver on this factory A10 printer? As I mentioned before, I did take the power supply apart right down to the motherboard, and did not see any adjustable pots on this specific model.
Any further help would be greatly appreciated as I am not finding any information on how to adjust the extruder voltage on the A10, all the information I have found on how to adjust voltage have pots, to either increase/decrease the voltage with a screwdriver.
I still don't have any pots that are adjustable...
So I see 4 adjustable pots (each driver?) how do I know which ones is for the extruder motor? I have not had any issues yet with the other stepper motors, so I don't know if I should temper with them.
