General Mach Discussion / Cannot get to 200 IPM

« on: January 04, 2014, 06:31:13 PM »

I have 2 motors on my X axis. I cannot get that axis to 200 IPM. I can get my Y axis with only one motor up to 200 IPM. Motors are kl-223h286-20-8b Drivers Kl 4030 power supply kl-350-36. all by keiling. I also have a smooth stepper usb type running version v17f and mach3 version 3.043.066. Do I need more volts to run the two to 200. Meaning buy another power supply.

General Mach Discussion / steps per or backlash?

« on: November 26, 2011, 06:03:05 PM »

I cut a 3" square and inside that square I cut a 1" circle. The x dimension on the square is 3.003 The y dimension on the square is 3.02. The x dimension on the circle is .985. The y dimension on the circle is .970.  So if I push up the steps per the circle will get bigger but so will the square. I have tried backlash but it didn't seem to help in the circle. I am using g41 in the program. But until I get Y matching X it won't help. I was hoping to get to + - .005.  I have tightened everything on the machine I can think of ( this is a router made from wood and alum. from build your cnc) and played with the settings in smooth stepper.   + - .010 I could accept or is this the best I am going to get.

Thanks for the replies

Hi, this weekend I have been trying to make4 my machine more accurate ( goofin with the steps per) but I noticed running my program that when it did the G28 X0 Y0 line it would go in the opposite direction a touch before going the right way and to home any ideas as to why or what setting I can change to make it stop going in reverse?

General Mach Discussion / Cannot Figure out

« on: July 13, 2010, 08:27:10 PM »

Hi I have been working on the software part of my build and I am stuck. I load one of the sample programs from the mach3/gcode folder and watch what it does in the toolpath window but the tool path (in green dashes) does nothing but circles the shape is there but and it will turn from purple to white as yop single block thru it but the toolpath just does circles and does not follow the part / shape. I went thru the tutorials and then skimmed them again but I can't find anything on a setting  I missed. Also I tried programing a simple square and it will only draw the first 2 legs. here is the code
G00 G17 G20 G40 G49 G50 G64 G80 G91;
G54 ;
G28 X0 Y0 Z0;
G00 X2.0 Y2.0;
G43 H1 Z.1;
G01 Z-.1 F25.0;
G01 X4.0 Y0 F50.0;
Y4.0 ;
X0 Y4.0;
 Y0;
G28 X0 Y0;
M30; 
What am I missing?
Thanks for your help

General Mach Discussion / Newbie gonna try to make one

« on: May 28, 2010, 07:04:06 PM »

Hi all, I am a cnc machinist with 14 yrs of operating settingup and programming g-code and conversational machines. I thought it was time I brought my work home   I bought a plans from http://buildyourcnc.com/default.aspx I thought I would start simple and get my feet wet, I have never set-up a machine in the sense of when it's new in the shop or having to fix a cnc machine, but I figured I have computer laying around and really want to do more 3d machining. So I will update, prolly very slowly as I go. I will say in advance, Thank You, to all of those who will answer my questions in the future.
