Just waiting for the video to load on YouTube!
Firstly, a big thank you to Ryan for being a good sport and inviting me to play with the V1 Engineering lot! I hope we can have some friendly competition here.
About my results - I made a rookie error and added a work offset, so I cut 13mm deep instead of 12mm. the width didn’t turn out great (you’ll see in the video) - but my next one will have a clean up pass.
Total machining time = 01.48 (mm:ss)

Welcome!
Love seeing any machine getting pushed like this, so fun.
Your hooked now, I think we all went straight into a second cut.
You did it the proper way, now go hog wild on it. Adaptive it the proper way, now really push it!
(I want a vacuum that knocks the dust off the filter, FANCY!?!)
It gives you a heart attack when you don’t realise its going to clean itself! it sounds like its distorting itself.
Here is my final entry for tonight:
Total time 01:36 (mm:ss)
I think a bigger bit is needed to bring the time down.
Okay people, I am going for another run.
In ESTLCAM if you choose, edit, machine order, automatic, Optimize, it really shaves off a bunch of time in travel moves.
On top of that I manually edited out the two Z hops it kept in for the finishing pass and shaved off a couple more.
OMG!!! 1 more 1/8" and I will upload a video I put on a fresh endmill. 
Okay
1:21, 1/8" endmill, I am pretty happy with it. Starting to make some noise so I think there is not too much more to eek out. (I know, I know…I should break something to prove it.
XY dims
99.63, 99.58, 99.93
Z dims
11.58, 11.98, 11.96. I think I had a few tiny metal slivers stuck to the tip when I probed (dang magnets), I think those all were normally a hair over not under on all the tests before.

I modified the gcode to get rid of the first set of finishing passes (the ones after roughing, before the actual finishing passes), got rid of two extra Z hops. Super fun gcode to modify I just edit the first numbers to say where to start, and then find/replace the roughing and finishing numbers.
12mm Depth of cut in MDF at 44.9mm/s Slotting!!!
Tomorrow…1/4" testing, I am going to need more MDF.
Can’t wait to see it with ¼" bits…
Yeah, I am very curious as to what can happen. Barry knocked it out of the park with a 4’x8’, what can this little beast do? How much faster can it possibly get?
That 1/8" was making a sound I had never heard before, a deep squeal/chatter is the only way I can describe it. Doesn’t come across in the video at all. Watching that back It looks like the accelerations need to be upped a bit, gain a few seconds for sure.
Cool, now I have ideas to edit my gcode.
I am excited to run the 1/4", try a single and a two flute. I’m coming for you Barry!
First run with a 1/4"…1:07!!! @20mm/s 12mm DOC.
Max deviation 0.38mm…not amazing but okay.
Here goes a few more tries.
30mm/s…50 Seconds.
Shoving some food in my face then another run or two!
Okay, 40mm/s no problem, ~:45 seconds
50mm/s, the firmware limit ~:40 seconds…Well crap. Now what?!? Full depth (12mm), in MDF, 75% stepover, no finishing pass, still within 0.4mm deviation or less, with a single flute 1/4" endmill. The only way to go faster is re-gear, 20T pulleys.
Running less stepover will not shave more than a second or two off If that.
DANG I maxed out the machine. Trying to let that sink in.
24X faster cut than when using the recommended settings in the milling basics. 24X
Wowwww that is amazingly fast 
now how about 3/4ply what will be the test for outline cutting ? Flat pack stools? 
The next race will have to include a tool change so the pit crew comes into play as well!
The primo is a wonder and I love mine always amazed at what it’s capable of
Can’t you change the max feed-rate in the firmware from the console or the TFT?
