The endstop sleeve is an element placed on the inner side of the axis block. It presses the lever of the endstop once the extruder reaches the end of the axis. This immediately informs the printer that the extruder should stop moving. The endstop prevents the extruder from crashing into the housing. Therefore, if the extruder hits the corner of the housing, and an error message appears on the display (Endstops error #034), check if the endstop sleeves are installed on each axis block. This manual gives instructions on the endstop sleeve installation.
M Series Printers Servicing
The Zortrax M Series includes two printer models right now: the M200 and the M300. These printers are similar in terms of design and technology. The most important difference is their size: the M200 has a 200x200x180mm workspace, whereas the M300 has an increased 300x300x300mm workspace.
Therefore, maintenance and repair work can be carried out in the same manner with both models. The following manual shows M200 repair work. For the M300, these procedures look the same.
Unplugging the Power Cable
Turn off the printer and unplug the power cable.
Unplugging the Extruder Cable
Unplug the extruder cable.
Loosening the Screws on the Axis Block
Move the extruder toward the axis block on which you will install the endstop sleeve. Loosen the two screws placed at the bottom of the opposite axis block using a 1.5mm Allen key.
Unscrewing the Axis Block Cover
Move the extruder toward the opposite axis block. Unscrew the two front screws on the axis block on which you will install the endstop sleeve. Use a 2mm Allen key. Slightly move the axis block cover away from the block to gain easier access to the place where the endstop sleeve should be screwed in.
Endstop Sleeve Installation
Turn the axis block and screw in the endstop sleeve using a 2mm Allen key. Turn the axis block to its previous position.
Securing the Axis Block Cover
Push the axis block cover closer to the block and secure it with the two screws.
Tightening the Screws on the Axis Block
Move the extruder toward the opposite axis block. Tighten the two screws placed at the bottom of the axis block using a 1.5mm Allen key.
Plugging the Extruder Cable
Plug the extruder cable in.
Plugging the Power Cable
Plug the power cable in.
