In this video I finally get to make the first print… I know how it turned out but you will have to watch to see 😉
Before the printing fun could begin, I needed to take care of some minor things, and one slightly more important thing – the power supply for the heated bed!
For the moment all power for the printer is temporary so I make use of a 12v power supply that I already had. It doesn’t have the output to deliver power to all, but it should take care of the heated bed and I will continue to use the lab supply for the rest.
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 😉
