Assembling the X-axis...

In an earlier post (here ) you'll see my x-axis design and trial assembly. It's come time to assemble it more precisely and more permanently. To align the x-axis ends with the vertical rod clamp positions I simply left some length on the z-axis rods, extended them upwards, inverted the x-axis assembly and sat it on top (see pict). This kept everything in position until I secured the x-axis rods.With the reprapped x-axis ends you have a captured...

Z-axis motor mounts...

In the Prusa Mendel variant there are two Z-axis motors, on top of the printer. They are wired in parallel, turning threaded rods connected directly to their drive shafts. They lift and lower the X-axis assembly, which is held in the vertical plane by two vertical rods. This is a much simpler arrangement for the Z-axis, and seems to be working well for others. The position of the motor drive shaft and the anchor point for the vertical slide rod must...

Y-Axis Stepper Motor mounting bracket...

Having received some Stepper Motors along with the electronics, I was able to tackle some barcket design. I've started with the Y-Axis Stepper Motor mounting bracket. Had some 3mm aluminium sheet which I figure will be strong enough, and relatively easy to work. I did a drawing (below), then cut and drilled out the plate to meet the requirement. Here you go!I've been working with 60mm between centres on the vertex joints, so you see that measurement...

GEN6, batch2...hmmmm...nice!

Mendel-Parts delivered this week! Thanks guys! I ordered motors, electronics and some other bits 'n' pieces. The Generation 6, (Batch 2) electronics is a neat looking board, even to me, and I'm not really that geeky. It's tiny (use the network connector for scale). It's amazing, and open-source... I'm so impressed and that's before I even power it up! :)The batch 2 version's characterised by the little black heatsinks on the stepper driver...
