Rostock MAX v2 User's Guide
Create and name macro #3, “X Tower” and use the following G-Code:
G28
G0 Z0 X-77.94 Y-45 F3500
Create and name macro #4, “Bed Center” and use the following G-Code
G28
G0 Z0 F3500
In order to make sure that each axis is higher than the destinations of the four macros you just
created, I want you to position the machine using the terminal window. Enter these commands using
the G-Code Terminal:
G28
G0 Z5 X0 Y90 F3500
Perform the same check on the other axes by issuing G28 followed by G0 Z5 X77.94 Y-45
F3500 and G0 Z5 X-77.94 Y-45 F3500. You're not after accuracy at this point, you just want to get the
nozzle from smashing into the build plate.
Once you're confident you can go to the heated bed without striking it, you can begin to
precisely adjust the end stop screws.
Click the “Z Tower” macro button. This will send the g-code you entered previously to the
Rostock MAX. Make sure you've got your feeler gauge under where the hot end will “land”. Having
these in macro form makes the repeating task of setting the end stops much easier.
Your goal here is to have the nozzle touching the feeler gauge just enough that you can feel the
additional friction of the feeler gauge “dragging” under the nozzle. You want that same amount of
“grab” to be equal among all your test locations.
You adjust the height of each axis by turning the end stop adjustment screw to the right to raise
the platform and to the left to lower the platform. Each time you make an adjustment, click the “Z
Tower” macro button. Repeat this process until you're getting the same amount of “grab”
on the paper as you did when setting the initial Z height. When you're satisfied, move on to the “Y
Tower” and “X Tower” macros.
