LR4 - The Fishening

In the beginning…

Build is in Brisbane Australia.
I’ll be building a 3000x1550 bench for it to go on. This will be a full sheet machine.

Will build stock LR4 first and get a baseline for the performance of the machine, then make a few changes to get obstructions off the bench surface to make the bench more usable as I have plans to make the bench multipurpose. But I need a baseline to know what I am losing in performance as I make those changes.

I finished my other CNC recently and was able to cut my plates out of 10mm aluminium plate. they turned out really well.

The other CNC can cut steel and aluminium with a build area of around 450x650.

  • Primary goal for this machine is to be able to cut contours in sheet stock - ply and acrylic/polycarbonate.

  • Stretch goal is large slab surfacing(may require some more modifications to get some more Z - we will see)

  • Stretch stretch goal would be to do contour cuts to process larger bits of aluminium plate - say 5 or 6mm 5083 and cut down to size to fit on the smaller metal cutting CNC.

I’ll be using a genmitsu router to start with, with the intent of upgrading to a 1.5kw VFD driven spindle down the track. I do not necessarily think I need the extra power - I have rapidchange style toolchanger on the other CNC and would like the same on this. The requires being able to reverse the spindle and have relatively fine control at slow speeds - not something I can do with the genmitsu router, makita or other clones.

Still undecided on controller. I originally purchased a 6x for this, but its in the other CNC and going great.
I have an SKR 1.3 I could use, along with a spider and some other boards. I could use those with GRBLHal however I am really liking fluidnc. I would buy a 6 pack but the only ones available on elecrow are external driver ones. May end up ordering a jackpot. We shall see…

Oh and I have a PicoBOB DLX + BOB that I can use for LCNC or GRBLHal on here until I get a fluidnc board to use. Either would work just fine, though LCNC may be excess to requirements for a lowrider…
I think this would be a better move than the SKR or Spider in the first instance.

Greetings from the Sunny Coast! I love the colour as the pic shows it - is it some sort of Vanilla Off White?

Hey Peter. Great another Queenslander! It’s Overture Natural ASA :slight_smile:
Natural ASA is pretty much my favourite filament. I know ASA is not recommended for lowrider - but I’m happy to take a chance here…

It’s got kind of a bone finish.

My experience with this specific filament is it’s very stiff and strong. Great for 3d printer parts, functional parts around the workshop etc.

Plus it’s what had on hand.

I think that is all parts printed. Temporary strut plates cut.not a lot to do before I can start building!
