Thread: Setting my table up...
Yes, resolution is fine on my build, I've had it drawing intricate shapes over and over for a good few days and it hasn't lost a step, these shapes are far more intricate than can cut with plasma so it's a pretty tough test.
I've got it in bits for final wiring etc, my new plasma cutter should be here this week, can start testing properly then.

Throwing a spindle on it will soon show you thou and cutting finish will show how the lower resolution is affecting things, esp with 3d surfaces and tiny stepovers.
Last belt machine I built was heavily geared, approx 5 or 6:1 I think to get the resolution down for the mostly 3D work it was doing. Thats was 3-4yrs ago and it hasn't missed a beat since and done some lovely work from the few pics that have been sent to me.
Ahh, I see, I very much doubt this build will see a spindle, it might however see a 3d print head being fitted;)
would need to be a fair bit tougher for a spindle I think.
where did your max of 4500 to 5000mm/min come from?
Purely from reading many hundreds of posts and asking endless questions. As I said, I have never used a CNC machine before but have cut a fair bit by hand and that seems to back up my theory on speeds.
dont forget that I am only concerned with lower power cutting, as I'm in a home-shop and very limited on power etc. A 50A cutter is about the limit, I know that would cut ridiculously fast on say 1mm sheet but it's variable and more control can be had by lowering it to 20A and running at a more controlled pace.
Just checking. It seemed 4500-5000 was being stated as some general maximum - which as you know is not the case.
50A - at home - see the street lights dim when you start that puppy
Next to me is a Sub station and you should hear that sucker buzz when me and my lad are on full tilt. . with 2 welders going at same and all other kit in workshop.!!. . . . . . Just hope the Elecy board don't spot the Cable running thru back wall of Station. .
nah, worst it can do is pop the breaker to the shop, if it does and likely will, I'll have to rewire and uprate the breaker, I'm pushing my luck well into the realms of stupidity as I have the shop running on a 32A breaker and intending to use a 2hp compressor, 6 fluorescent lights and a 32A plasma cutter :)
luckily the the cutter can be run at lower power on thinner stuff, but I am expecting to rewire soon.
New torch and psu arrived today, this thing is a beast!
not had a chance to power it up yet as I need to make a torch holder to fit the massive machine torch it has.
The tip is totally different to my smaller unit, must be half a pound of copper in the tip :o
Hopefully get the table cutting this week.
