Geeetech

Hi all,

I have problem with under extruding... i have tried calibrating it but turning up the e-steps does literally nothing... i had it working good for alittle bit on 110 but now it looks really really slow and weak to come out.. ive tried putting it up to 500 and hardly makes a difference.

I think this is a weak motor, can I increase the voltage on the driver? which one is it? does this make the motor run quicker or anything?

OK UPDATE!!

i switched out the driver from the Z axis to the extruder, now it looks like the extruder is extrudding properly.. the lines look much thicker

BUT now the z steps are playing up and wont go up properly which wasnt happening before.... which tells me that driver is faulty or needs the voltage increased maybe??????

Hi


You can solve problems very well, but you still have too little knowledge. Acquire knowledge on the forum.

I will tell you a little.
I will write it again... Especially for you.

Each stepper motor control module has the ability to adjust the Vref voltage. This has an impact on the current supplied to the motor.
The engine can work more reliably - it has a little more power.

Incorrect adjustment of the motor current will cause the motor to overheat.
It is best to select the setting experimentally, but you must be careful

For making this setting, it would be good if you had a multimeter and a small flat screwdriver.

You can read the rest in the forum
Not necessarily in this subforum.

I greet you warmly.

Just to double check: have you got your nozzle width right? In repetier, the default is 0.4mm, however, Geeetech I3 Pro B has a nozzle with 0.3mm. Although this should rather cause over-extruding (and also clicking sounds/skipping steps).

Also, check temperatures (try 200-210 degrees?).

Just my ideas.
