Feed Pressure
–
Check/Restore to Factory Default
Feed pressure is factory set and should never be changed.
Figure 6.23.1 Feed Pressure Adjustment Diagram
If you need to restore factory setting:
1)
R
elease nut “A” with a 10mm spanner, holding “C” wheel.
2)
Lock feeder into OPEN position, locking it into position as from above pic. 6.
NOTE
- For older machines the position could be slightly different. Proof of good setting can be seen
during printing process, when machine is repeatedly feeding and retracting
–
the leve
r shouldn’t move –
if you can see some fluctuation
then the feeding roller is “chewing” the
filament (showing that either
pressure is too high, or filament is too soft).
