Ok, glad to hear it

It looks like I have the same problem!  I got this CNC set it up and run the program but it is cutting backward (mirror) and it is cutting really really small. I attached some information might be helpful to someone wants to help me. Thanks


The use of high-precision ball screw:diameter 16 mm; pitch 10 mm;

Router is the length of 50 inches, width is 33 inches, 120cm 84cm
Effective processing distance: X = 40 inches,Y = 24 inches, Z = 5 inches (100cm 60CM 12CM)；

NEMA23（Y-Z-A) and NEMA34（X) 3A stepper motor ；Maximum engraving speed of 6 M / min;

30v 3A  CNC drive

Info that is needed is

Stepper motor or servo, you already said  stepper so thats fine.
Pitch of screw, which you have already said so again thats fine.
Native units you will use, you have a mix of metric and imperial in your description but likely it will be metric as you mention a cutting speed of metric units.

So info still needed is

Drives microstepping amount ??
Reduction between Motor and Screw??

Hi Mr. Hood,

I set up the Native units in inches.
I have the info on the link [http://www.icesculpturepro.com/mach3-6-2.JPG] what numbers I copied  (Steps per,velocity/acceleration) from the screen shot. I guess where all my problems coming from sorry I'm newbie on this. Thanks for your help.. 

Assuming you have no reduction between motor and screw then your steps per unit should be set to 4064 steps per unit. The Velocity you could try at 315 and accel try at 20 and see how it goes. If the motors stall then reduce the Velocity and Accel by half and then increase the Accel slowly until it stalls then back off the do the same wit the Vel.

Thanks Hood it is running okay now, but when I load the G-code, Mach 3 is not loading all the g-code and the tool path is not complete in the mach3 screen. I tried my code in the other machine and it is all fine. Can you help me with this one. Thanks again.

You are in demo mode, ie no licence file in the Mach3 folder.

Ok. thats what it is, Thanks I'll get a license then..

Mr. Hood,  I upgraded my z axis from 6"  to 12" processing distance. Now I have lead screw

-0.1 pitch lead screws. Standard (Feed rate of 150 inch per minute)
-Kerk(TM) Nut
+ Resolution .0005"
+ No load backlash .0005"

+ Double End Support.
