3D Print Bed Overview
WHENEVER CHANGING BEDS, ALWAYS REMEASURE THE Z AXIS TO REDUCE THE CHANCE OF CRASH
The H-Series 3D Print Bed attaches to the machine using the four magnetic latches on each corner of the bed support. When installing the bed on the machine ensure that the tapered pins (and the axis engraving, if present) are facing towards the operator.
The print bed is shipped with a 0.006 in (0.15 mm) layer of Kapton film adhered to the printing surface of the bed. This material is particularly useful when printing TPU materials. The print bed also includes a series of M3 tapped holes for use in attaching other surfaces to the bed.
The tapered pins can be used to help ensure the level of the bed for subtractive functionality as shown in the 3.4 Leveling the H-Series Bed.
NEVER REMOVE THE BED WHILE THE BED HEATER IS POWERED! IF YOU ARE UNCERTAIN WHETHER THE BED HEATER IS ON, PUSH THE EMERGENCY STOP BEFORE REMOVING THE BED.
The bed heater uses a non-locking connector, which means that the bed can be removed without disconnecting anything. This also means that the bed can be removed while it is powered, which will result in an electrical arc that will damage the connector pins. Whenever you would like to remove the bed, do one of the following:
- Set the bed temperature to 0,
- press the software emergency stop,
- press the physical emergency stop button, or
- press "turn everything off" in the control interface.
Never remove the bed while it is powered (it is OK if the bed is still warm).
Otherwise, the bed heater operation is straightforward. The bed can be placed on the support pins, locked in place with the magnetic levers, and set to the desired temperature (up to 100C). If the firmware reads a temperature fault when the bed is removed, then you must send "M562" to the controller before you can heat it again.
