It’s difficult to remove an object once it’s done
Once a print is finished, it’s sometimes difficult to pull it out of the platform:
•
Use less amount of lac.
•
It is highly recommended to remove the cristal base by loosening the white screws. If you try to extract the
printed part directly without removing the glass first, you could be forcing the screws and/or misaligning
the platform.
Motors do not rotate correctly (adjusting the pololus)
From Home Menu/LCD Prepare/Move Axis, the proper movement of the motors
can be cheked by moving the axes. We will proceed as follows:
1. Before we start, use your own hands to check nothing is hindering the motors
movement.. If there’s still no movement, adjust the pololus following this instructions:
2. If the motors do not move or do not move enough,
They are lacking power. Turn off the machine and turn the potentiometer clock
pololu 5 minutes clockwise.
3. If the motors move but, from time to time, make sudden movements, ie, lose steps, they have too much power. In
that case, turn off the machine and turn the potentiometer clock pololu 5 minutes anticlockwise.
NOTE: before clicking on this option, make sure nothing obstructs the movement of all the axes. E axis will not move unless
the extruder is hotter than 150ºC.
Extrusion stops
It could happen for several reasons:
•
The motor does not properly rotate:
1. Adjust pololus power.
2. Check that the large gear axle nuts are not too tightened up against the extruder, but against each other. Ensure
that the actuating mechanism rotates easily by hand.
3. Check for flaws in the electrical cables and that they are properly connected.
•
The thread does not advance even when the motor is running:
1. Make sure the temperature is correct according to the type of plastic.
2. Remove the extruder and thoroughly clean any remaining plastic.
3. Raise the machine temperature and, using your own hands, try to get rid of the clog jamming the extruder.
