Wow its been a while since I updated things.

The Big Red beast is still going, been cutting a little here and there but nothing major.

My future plans call for stability and accuracy so I went ahead and started the twin 6mm mdf gantry revealing job and almost have it done. This last effort is to take 1.8mm out of one of the front wheels, just having a brain fade on which one

I have also ordered the Wixey WR525 digital measuring kit to get my distances spot on, hopefully that will arrive soon.

And the big one is I have just ordered a Centroid Acorn kit, a Mill Pro licence and one of their Wireless pendants, all a bit exy here in Aus ($AUD975.00) but I hope things will improve over using LinuxCNC/Pathpilot. Expensive mistake if it doesn't!

With Acorn I just have to figure out how to set the Axis "steps", Acorn does it differently than every other piece of software out there. The Rack & Pinion thing has me stumped at the moment, especially since I am using metric racks, metric pinion and pullies, Mod 1 to be exact. All part of the deep learning curve to come....

Cheers

Got a few goodies from Centroid, my wireless MPG, Acorn board, Power Supply and 8 relay board for the outputs. I am waiting on a new computer to run CNC12 but that should be with me tomorrow.

I'll grab a shot once I am finished in there, still need to wire up the spindle/VFD under Acorn PWM control.

That video is an air cut of a 600mm Mayan calendar. I ran that under LinuxCNC using Tormach Pathpilot software and it took 2.5 hours. My aircut finished in 1:41, a full 50 minutes faster. That is with Smoothing on in CNC12. I will run another once the spindle is up and running for real and see if there is a difference in quality.

I have read multiple times that Acorn improves cut time, I wondered if it was true - it definitely is!

Cheers
