SmoothStepper USB / Re: ESS and poor motor response
« on: May 30, 2015, 08:12:07 PM »
I have a 48V power supply. Mine is a 7.3 A. I understand I need a 12.5 A. to run 4 steppers. My system worked just fine (other than being extremely slow) until I switched from a Win XP desktop to a Win 7 laptop and added the Ethernet SmoothStepper. Now all of a sudden the NEMA 23 steppers are running hot,slow and rough. The Z axis, a NEMA 17, runs just fine.So can anyone explain why things changed by adding the ESS?

SmoothStepper USB / ESS and poor motor response
« on: May 26, 2015, 03:59:51 PM »
 I found the ESS install & configuration instructions for my steppers on  the cncrouterparts.com website and followed it step by step. I  have motor motion, however, the Y axis (with the slaved A motor) and the X axis run hot, slow and rough.  The Z axis runs smooth and quiet. Can anyone help to smooth out these motors? Is my Dell laptop causing the problem in any way? Did I get a bad ESS board? If I connect to my turtle-slow Win XP desktop, the steppers run fine. Thank you.

Does anyone have G Code for a wooden computer mouse project that they would be willing to share or sell?

Mach 2/3 ATC Arcs, is for when your machine utilizes an Automatic Tool Changer. (ATC)

If the job uses multiple tools, if you all the g-code for all tools in one file, you must use the ATC post. Even if you change tools manually.
The Mach2/3 Arcs post only allows one tool per file.
Thank you for your input.  :)

Mach 2/3 Arcs, is what you would use for normal cutting jobs.
Mach 2/3 ATC Arcs, is for when your machine utilizes an Automatic Tool Changer. (ATC)
Mach 2/3 wrapx2a, is for rotary work where you are wrapping the X axis around your A axis.
This is dependant on how your rotary axis is set up. You may need to use Mach 2/3 wrapy2a instead.
Thank you. Now I am just a little bit smarter. :)

General Mach Discussion / Mach3 install question
« on: April 02, 2014, 10:54:11 AM »
Downloaded Mach3 demo some time ago to try it out. Got my (licensed) Mach3 disc yesterday and installed. When I open up the program, at the top of the screen it still says "Mach3 Demo". I thought the licensed version would override the demo version. Can anybody explain why it didn't.

General Mach Discussion / Slaving steppers
« on: February 28, 2014, 12:21:11 AM »
Could anyone here explain to me (a CNC router beginner) how to slave 2 steppers on the same axis ("Y") running one stepper reversed? (Thus both moving the gantry in the same direction.) I have 3 Geckodrive NEMA 23 steppers with a G540 control board.
