New build with recycled parts on a ridiculous budget 120cm*60cm work area

That's my board so we'll see tomorrow ;)

Really liking the 3d mouse gives you so much more control over how you view your model.

The southpark figures are 3d illustrations?? The wood grain looks wrong to be real cuts?

Renders from within Fusion 360. Shows how good they are, the need to check / question :-)

Chaz is right there Fusion 360 models I then "coloured" using different woods in physical material.

I was playing with different ways of making cad models from bitmaps

The South Park figures were a simple spline trace over a canvas, Obey from They Live (Cracking film) I used Inkscape trace bitmap function to vectorize the image then used the SVG to extrude from.

This is one I did from a photo of a friend this took a fair bit of processing in both gimp and Inkscape before I could get a usable extrusion will need cleaning up before I make it.

Also going to check out image2gcode built into linuxcnc to see what engraving fun I can have ;)

Was playing in fusion only took 40 mins but not sure how I'd drive the long axis, I think needs to be R&P but have no idea how to set up a dual pinion anti backlash setup. The other choice 2* 2.7m 2510 ballscrew's with rotating ballnut's as at the length it's going to be a skipping rope if I try and rotate the screw.

Does anyone know how I invert the axis in linuxcnc? Using the beta dual ballscrew on the Y so need to edit the hal or .ini to do it as the wizard doesn't support dual motors.

Alright Fusion buffs when I copy an object how do I break the association so my edits to the new object do not effect the original?

**Davek0974** · 16-12-2017

Man, do i need to brush up on Fusion, 40 minutes? would have taken me a week :) Thats if i could figure out where to start

**Nr1madman** · 16-12-2017

Are you sure you need dual pinions if using r&p?
I think the more common option is to spring load the pinion against the rack.. have you checked cncrouterparts design with a pivotplate or the mechmate as it uses similar design.

And I agree about your fusion skills! Impressive!
I find solidworks much more intuitive but I have a really old version so I guess fusion tutorials are on that to-do list ;)

Dave

For twin screws you need Linuxcnc V 2.8 master if you want independent homing. I you want to reverse on of the motors then you can just swap the phases around on the motor.

What version are you using?
