PrintNC Update - Spoilboard & Workholding

[@Trevieze]

That's a really nice spoil board. Great job on your mill.

[@f15sim]

Thanks!

[@wv838]

Great to see it finished and working so well. It looks darned good too! Really nice build, you should be very proud of it.

[@f15sim]

Thanks!

[@BryanHoward]

Congrats!

[@f15sim]

Thanks!

[@recube_games]

great to see this thing running so well. Does the spoil board expand with heat? humidity? or are you pretty much good to go after this first leveling pass?

[@f15sim]

There will be some changes with humidity - that's what wood does after all. MDF is just sawdust & glue. I won't need to re-surface the spoilboard until they get pretty chewed up with use.

Congratulations on your finished machine, how long do you reckon it took you to build it? And how much previous knowledge did you have regarding electronics?

[@f15sim]

It took around two years of on and off work to get it done. I'd consider myself very comfortable in working with electronics, but I'm no EE. ;)

Looks like the plywood base (under the spoilboard) is two piece split in the middle. Wondering if this by design or just what you had on hand?

[@f15sim]

That was by design. I wanted to be able to gain a bit more work height if I needed it. The base is made from 18mm Baltic Birch plywood.

[@RichMenzel]

@@f15sim It looks like its bolted to the cross frame with counter sunk bolts. How did you secure the bolts, threaded holes in the cross frame or maybe through holes with nuts on the bottom? I wondering because if the plywood base ever has to be replaced, how do you duplicate the hole pattern on a new piece of plywood?

[@f15sim]

@@RichMenzel I drilled the plywood base board halves on my ShopBot (including inset pockets) and then used those holes to mark the cross members. I then drilled & tapped those for 6mm button head screws.

[@RichMenzel]

@@f15sim Thanks for the feedback.

[@xyzspec82]

Looking good

[@mildlemon7866]

just awesome.

[@user-jp1qt8ut3s]

How do you tweak it? Is there a design with adjustable Z axis for the printnc?

[@f15sim]

There's features built in to the Z axis design specifically intended for tramming the spindle.

[@user-jp1qt8ut3s]

​@@f15sim thanks, I looked into the design and I understand how tramming bolts work now. I start right away to design a tramming plate, bye!!

[@just_bright]

I'm gonna probably have mine done by 2026. But I do have metal finally and all the parts

[@Trevieze]

It took me 13 months from buying the steel to making my first cuts.
