Not the most exciting video in the world but IT LIVES!!!
Did lots of testing this afternoon. All axis move smoothly, PID tuned the heater and bed. Set end stops and initial steps/mm calibration.
Have some concerns about bed levelling. I don’t yet have a suitable probe (plan to use Piezo eventually) so will need to do it manually. I have an adjustable optical end stop on Z so hopefully I’ll be able to get it close enough to maybe do a calibration print at least (once I have printed an extruder)
Plenty still to do but am very glad the electronics worked, and every single cable I made worked first time
Am running Klipper firmware on a RPi3 and an MKS Gen 1.4, which is like a single board RAMPS.
@Glen_Beer Yep. I have a 24v PSU but was worried that the bed and everything else might be too much current drain (bed is 1.4 Ohm so at 24v would draw ~ 17Amps) so I dropped the voltage of the PSU down to 18.5v (which should be about 13Amps) and it seems to be OK with hot-end and motors running.
@Steve_L This is the Hypercube Evolution built to about a 350x360x300 build area. All in it has cost me about £450. Almost all bits were bought individually from AliExpress except for the ground precision rods and the aluminium extrusions which I got from an EU supplier called Dold Mechatronic.
