Exactly my point. . . It's job dependant.!! Provided you have the spindle power and machine is capable then In practice you'd use the largest size you feel you can get away with.

My preference would be to have all parts in the case and not mounted to the door - Is there enough room to mount the powers supply on its side? Might give more room/options?

Approx 80deg from vertical. The gantry runs Vertical but mostly because of machine design not being optimised for standing vertical (I didn't build this machine and to make vertical It's just...

Your talking about different things again. Fault signals do just that and signal faults but you still have to turn the drives and things on in the first place and this requires power to pass thru...

If your going to have Inaccurate home switches then there's no point having them at all really.! . . The whole point is accurecy and repeatabilty and you'll lose this thru a relay.

If the KK01 can...

Ok I've done you a quick Diagram but If your not going to listen your just wasting peoples time and I'm time short as it is.! So either take heed or don't waste my time asking questions your going to...

Ok well maybe we are at odd's here.? It looked like 2 switches for Limits and I was meaning just have one switch that traveled.

But call it option #1 if your wanting to Share one Switch for Limits...

They are without doubt the best BOB on the market. Steve stallings at PMDX is great bloke to deal with and will answer any questions or troubles you have.

Just to make you aware regards Mach4....

If you don't require slaved motors then I would still go with the IP-M over the ESS despite the ESS being higher spec'd and here's why.

The ESS still requires a BOB and to get the best from it you...

30A consumables arrived today, gave them a spin on 1.2mm 304 stainless and got excellent results http://www.plasmaspider.com/images/smilies/icon_e_biggrin.gif ...

I did some comparison price wise , plus i designed some cheaper and sturdier solutions, look post #165

Personally i finished using only UPN140 profiles, no spaces, and a lot of threaded fixing...

No won't hurt it them at all.

Also Suggest you wire the alarms in parallel so if any one trips it turns on a relay. Put the E-stop thru a NC contact of that relay.
This means the relay will...

Quick answer to your question about "2 volt motors". Ignore motor voltage ratings. For all practical purposes, they are irrelevant. The control electronics are driving short pulses through the motor...

HTD 5M 15mm wide is the standard belt size most people on this and other forums use for nema 23 and 34 motors and servo motors.

You have got it wrong here. If it was a sheet or just box section profile, yes, its like you say. But not in that case. As it happens that i make various musical instruments and trying to make some...

Hi Alex,

This is how I did it . . . .

Yep, similar. As i described it above. Though tit did not come to my mind to use only one limit switch at Y,:cat:, anyway, i bought more than i needed.

I would say that the 4 most important things...

Yep just beef up the Ballnut mounts and your set to go.!
One thing I see is that you don't have much room for adjustment or alignment with that threaded bracket setup so give a little thought to...

What I mean is that there's no difference between Mach3 inputs and Arduino inputs Both are using and relying on Computers for safety.(BAD news) So if you had the spare inputs you may have well just...
