1. I believe in open source
2. More real time kernal than windows which is important when using a PP BOB. If you're using the BOB I have with Mach 3 you need to run windows 7 or below 32 bit edition. Linuxcnc still needs to be 32 bit edition for PP BOB's.
3. It's FREE!!!

I worked the assumption that linuxcnc will be more difficult to setup but once working properly neither would have an advantage over the other for a simple router like mine.

You make good points!
Im gonna use uccnc..
Bought a second hand uc300 controller and got the uccnc license included.
Read alot of positive comments about uccnc so it feels good.
If I was gonna use PP like you I would probably run dual boot win with mach3 and linuxcnc ;)
Have a feeling I would be switching back and forwards trying to decide whats better :D

Oh and about your limitswitches, hope you get them mounted in a good manner :D
Im still planning where mine should be.
I want travelling switches with static targets.. kind of hard thinking about where they should be on each axis without limiting travel or crashing into anything haha

Not so sure about that

Im envious of your drive (and time.. most of all time)
Arent you atleast curious about your current machines limitations and capabilities?
Understand me correctly now, if you learn more on whats failing on your current build you might get better insight on how to make it better? :)

It'll take me 3 months to scrounge the parts so plenty of time to work out what I want to change but there's 2 things I already know.

I need more travel 1.8*0.8m at least and I need it to work faster a lot faster:)

Nice upgrade!!!

**Nr1madman** · 23-01-2018

I have missed alot ;) but what speeds are you currently using?

4.5m/min seems to the top speed for the gantry which is where I thought it would be (Screw whip is just over 1000rpm for this screw, 5mm pitch)

The Y axis is a lot speedier been able to run that at 7m/min so far might be able to push it a little further screw whip is just over 2000 rpm for this screw, 4mm pitch,

I'm going to use a 4nm motor on the gantry (2nm at moment) with the 2010 screw.

Of course the Y axis will be turned into R&P when I upgrade but for now if I can the whole machine running at ~8m/min I'll be a happy man.

In theory I should be able to spin the 2010 so I can get 13m/min but that's really down to how accurate is the mounting and how good are the bearings I bought the cheapest screw so the answer is probably not that good lol.

I'm going to go for 2.5m travel on the Y because if I'm going to do it I might as well do it right so I can process 8*4 not that I would ever want to touch that horrible crap I'm a real wood kind of guy.
Also the cost difference is couple of hundred quid now.

As Christian Slater said it's better to have a gun and not need it than need a gun and not have it just replace with cnc travel ;) Might not be quite as catchy.

I'm using a 2.9ghz I7 to generate pulses not sure where my speed limit will be but I know the controller will need upgrading going to get what Clive suggested as I want to stick with linuxcnc.

7i76e I think but of course I'll order the right one from the States.

No need to buy from the States you can get then from Germany or Portugal also the speed of the processor does not effect the pulses as they are generated on the card.

If you change to R & P then it will not cut ally as good. Timber you need to cut fast ally slow and need better precision .

I could do a Dual gantry, been toying with it for a while on a switch so I can use either gantry with shared electronics, PSU, etc & 2 different profiles in linuxcnc. Share the rail, one R&P driven and the other driven by the 2 1m ballscrews. All seperate limit switches will be crazy wiring lol but not impossibly crazy.

When not in use I'll park the spare gantry out the way past the limit switches for the gantry that's working.

Cost is ~£600 with another 2.2kw spindle which is cheaper than building another machine of course and best of both worlds although I can only work one at once of course but since aluminium will very rare but the cost of outsourcing anything I want to do so high I can see it's worth it.

I could keep the 1605 ballscrew I have now for the 2nd gantry after all it doesn't need to be fast I only need fast for wood as my designs will fill the bed fior almost every cut and will be 3d milling 50+ pieces out of every bit of wood this will get old quick. At the moment going to have to cut real wood sheets in 1/2 to process them.

Doing the cam in fusion is getting old quick as well lol at some point will probably buy Vcarve pro.

Dual gantry opens up many possibilities although not with out headaches, but I could pimp it out with AM882's all round (So 8) and run both at the same time and be glad I got that 1kva transformer after all.

This would turn it into 1 1m*1.2m machine and 1 m*1.8m machine so would need 3 setups but opens up considerble time savings for certain things.

Holy crap batman!
Im hoping I will be satisfied with 5m/m.
It sounds fast.. dont know how fast it will feel like though ;)
