Bosch POF 1200 AE Height Adjust modifications

@Ned So Maslow_Motor_Mount.stl and Maslow_Nut_Mount.stl are the final ones?

I ordered 10 T8 200mm lead screws from aliexpress ($4 each), i sent a mail to confirm the price to print the new pieces since they’re a little bigger (probably around €20 per set). When they arrive i’ll go find a box of screws (a few cents) to fix the nut mount and i’ll figure out what way to ship them the cheapest and easiest (no idea of the cost, i guess around €10). The idea is to ship them to europe only, I don’t think it would be economical to ship them to Australia.

I am moving in 5 weeks, so things will get hectic over here, but i’ll try to make this a priority :slight_smile:

Bar said he’d add them to the store when so they get sold more easily. I’ll keep you posted on the timeline.

yup, thats correct :slight_smile:

I tried making my own ring, with the circle jig included in the pof 1200. It was quite dificult to get the inside of the circle smooth. But i think it should work once i cut down the bolts.

Just an update, i ordered a test piece first, before ordering a batch, they turned out just under €20. The 3d printing guy said pet would be plenty strong, so i’ll try to break my test piece when i get it, and then order the rest.
The lead screws are in a container on a ship somewhere i assume. Maybe on a plane, with free shipping you can’t be picky :slight_smile:

I love the way they reverse the cap to turn it into an adjustment knob!

Alas I do not have a Maslow, but I do have a 3d Printer and based in the Uk (not NZ)

So give us a shout if anyone this side of the world wants a set printed, its about 43g of plastic.

Btw for the nut fitting 4x M3 8mm goes in well.

also wonder if with a pipe cutter we can get more travel, still need to put mine together, I might need to adjust the nut as it printed very tight, maybe a couple of slits and a hose clamp if it fits.

300 mm is a bit much, 150 or 200mm are fine

Ok, the lead screws just arrived here from china, I didn’t order anti backlash nuts because the spring of the router already does that i assume.
The 3d printed parts should arrive in the following week from 50 km away. Guess that’s the way the world works today.
If they turn out fine, the final price should be €25 + shipping
This includes:

  • 200mm lead screw
  • The 3d printed part that goes into the router
  • The 3d printed part that goes between the router and the z-axis motor
  • 4 screws to fasten the internal part
  • My gratitude when i’m not stuck with a bunch of unsold kits :smiley:

I have 10 kits in the pipeline, if they sell out i’ll make some more

The guys at the customs office have been making something really cool with my maslow for the past week i assume, but if you want to be really sure that it really works you’ll have to wait till they are done so i can do some testing.

Test pieces arrived. It’s good, got 55mm of movement. need some small modifications and i expect them to arrive next week. The coupling in the video is smaller then the original maslow coupling.

Is this printed nut adapter just pressed or is it glued to the tube?

i just press fit mine, but you could rough up the tube a bit and add some epoxy if you’re worried about it. Maybe drill a hole or 2 through it for the epoxy to fill into and grab into

I had to lightly force it in place, then i drilled the holes with a 1,5mm drill, and then put 3mm screws into it which hold the nut, and clamp the nut adapter in place. I can’t get it to move without breaking it (or unscrewing).

Was it difficult to reroute the power in the router?

No there is a small pocket gap in the casing for the wires to sit

,
which keeps the wire clear of the moving shaft of the z axis
