Check Your Endstops
Locate the blue reset button near the USB connector and be ready to press it if an endstop does not
function. Click the “Stop Motor” button in Repetier host to make sure the motors are not engaged, then
manually push the extruder to the right end. Click the “Home X” button in Repetier host, then tap the X
endstop switch. The extruder should begin moving left and stop when you hit the button. When it stops, it
will reverse a few millimeters, then move to the left again more slowly for a few more millimeters. If the
extruder does not stop when you tap the the endstop switch, check that the stop is not obstructed. If it
works, click “Home X” again to ensure that the X carriage properly touches the endstop when it gets to the
left end.
Repeat this procedure with the Y axis, starting by moving the platform manually to the front.
Click the “Stop Motor” button in Repetier host again and make sure that your Z axis is at least a few inches
above its endstop so that you have time to react if the axis does not stop, turning these screws by hand if
necessary. Unlike the other axes, Z has enough mechanical advantage to potentially break things if it does
not stop, but is also moves much more slowly.
Click “Home Z”, then test the Z endstop again as above. Be sure to keep your finger on the reset button in
case the endstop does not function.
Lift your Z axis to 100mm using the jog controls.
Check your heater
Switch to temperature curve view. Set temperature to 60 and turn on the extruder heater.
Check to see that the extruder 1 temperature (thin red line) starts moving up (it should be pretty fast)
If it doesn't start to rise after a few seconds, see the “troubleshooting” documentation. Turn your extruder
off.
Assuming it did work, continue with the setup.
Aligning (“tramming”) the platform.
The term “tram” means to make your platform parallel to the X/Y plane of the machine. This does not need
to be level (perpendicular to gravity), and in fact your machine should be able to print upside-down.
Tighten your three platform mounting adjustment nuts until the springs are fully compressed, then home
your Z axis. Click “Stop Motor” to make sure your X and Y motors are disengaged and turn off the power
switch.
Move the extruder and platform by hand until the nozzle is over the glass nearest one of the adjustment
screws, and loosen that nut until the nozzle just touches.
