Bit of a monster video, for me, at nearly an hour. It is compacted as much as possible but there is a lot to fit in!
You can use these links to jump to specific steps in the video:-
Step 1 – Limit Switches
Step 2 – Motor Direction
Step 3 – Homing & XYZ Zeroing
Step 4 – Maximum Endstops
Step 5 – Bed Levelling
Step 6 – Z Probe/Bed Sensor
Step 7 – Extruder Calibration
I power on the printer for the first time and set up the Limit Switches, Axis Movement, End Stops, Bed Extents, Bed Levelling, Z Probe/Bed Sensor and do the Extruder Calibration!
I spent quite some time going through the Marlin documentation to see what each possible configuration instruction could do. I had already done a very basic run through of the Configuration.h file in this video/post but now it was time to get it spot on.
One side benefit of the exercise is that I can see I will need to change the way I mount the heated bed. Most importantly the nyloc nuts sitting on top reduce the Y axis extents by nearly 25%!!!!. But secondly the ply wood under the bed allows the nuts to squash the edges down too much, resulting in the opposite bed bend to that I had before! Still, good enough for a first print 😉
