I heard about that, I'll chase it down.
I made some frog-legs (a stand for the printer) and modified the Lilly-Pad controller.
By adding M117 Ext:{first_layer_print_min[0]},{first_layer_print_min[1]},{first_layer_print_max[0]},{first_layer_print_max[1]} to the custom gcode in Prusa slicer , I can automatically select which heaters to use on the segmented bed

Well HF would have replaced the 8" caliper, but they didn't have any, none within 100 miles. Soooo... I ordered an 8" Mitutoyo.
I added another 10mm to the width of the front axle, but it's about as far as I can go with it until some more little doo-dads get here.
While I'm waiting on more bits and pieces too arrive, I've started working on the rear suspension. I'm planning on making something like a Hendrickson Walking Beam suspension. I downloaded some of their tech info, and it's got enough illustrations that I think I've got a pretty good handle on how things should go together - time will tell. I've had to make some minor changes to my differential housings, to add locations for the equalizer beam brackets and the torque rod bracket. When I'm far enough along to start printing out pieces I'll show you what I came up with.

I left it at the end of the last year working OK ,but, when I returned to the other day my resin printed stepper motor end-plates had distorted and jammed due to creep.
So, as a quick fix ,I redesigned it to use the stepper motor with its metal end-plates. After several failures, involving temperature resin selection and weak supports, i finally have it vack together
Next is to design a new extruder with a different (lighter) motor with a mechanism to allow the hot-end / filament guide to be swapped out (with the long-term aim to have a tool changer)
