There is a stepper motor calculator speed sheet (MotorCalcs.zip) here:
What size stepper motor do I-need.

I brought from: world-etrade WATER COOLED MOTOR SPINDLE 1.5KW & VFD INVERTER 1.5KW
Chinese, Huanyang, water cooled, in 2013 I paid $148AU for both spindle and inverter.

It has worked fine (but...

I have Mach3 installed and running on my development PC which is windows 7 64bit, however I have not connected to a CNC controller. So I guess some 64bit systems it may work.

This might be a bit...

Your question is quite generic, so it hard for people to answer.
When you change one item then you tend to reevaluate every other item.

How much torque depends on factors like the lead screws...

I put your "router mount 2 nc.txt" file into Mach3 and it worked fine for me.
I had to change the Config settings to Distance Mode=Absolute and IJ Mode = Inc for it to display correctly.

Hi Brian,



Don't you mean the Leadshine kit power supply is rated at 48v 10a with 12a peak?

Can't the MX4660 be run from a big power supply like 1000w 48v 21amps?

like:
(SCN 1000 48)...

Perhaps try cutting a flat surface and see if you also get similar results.
Can you step through the code (in mach3) and see the tool path dipping and rising at the waves? Then you will know it is...

What about using double floating instead?
Is there much difference in speed using fix and double floating?

Also if you find your screws starting to whip: some people that have installed ball...

Perhaps make two perfectly square blocks with holes the same size as the pipe diameter. Put the pipe in the block holes and hold by screws. Mill first slot then rotate blocks(pipe)over 180degress....

I don't use ArtCAM pro, but have made 3D displaying software.

I assume you are talking about what you are seeing on the screen. Not what you see in the G Code generated.

I'm in the process of getting together gear for a 4x4 steel build (1200mmx1200mm). I expect to spend about $3000us (maybe $4000)
I will cut half a sheet of aluminum at a time (but hold a full sheet...

"Machine with a long boot will send touch sound machine" this sentence does not make sense. What type of CNC router are you talking about. What manufacturer and what model?

Test gantry for movement by grabbing one side of the gantry and try pushing it. Also try pushing the router or bit. If you have any movement you will have problems.

Many years since I used MFC.

But It sounds like the MFC dll file is the wrong type/version.

Can you set the C++ project configuration: Set MFC to "Shared DLL" or to "Static library"? (do for...
