General Mach Discussion / G53 & G28

« on: April 09, 2016, 05:01:13 PM »

Can anyone tell me why my Mach3, G53 & G28 are doing the same thing. I have another thread called gcode mishaps so you can see what is happening. I can cut anything because may x scale is out and my z seems to act crazy at the first of a gcode run and unpredictable at the last. Can anyone help?

General Mach Discussion / Gcode mishaps

« on: April 02, 2016, 05:45:38 AM »

Hi everyone. I am having trouble with either getting false e stops or running out of data on my ether net smooth step. The gcode that I am running is short it is face milling my cnc bed. I had bobcad support look at the file to see if everything is good and it is. Soon times when I first go to run the code the z axis goes from zero away up in the + and it is supposed to go up 2 then go to -.001 and start cutting . I cannot for the life of figure out what is going on need help

Mach4 General Discussion / Gcode mishaps

« on: March 29, 2016, 06:47:44 AM »

Hi all I am far new to cnc ing. When I set my Z 0 in the work Cor and run a gcode it is supposed to go to -.001 to start cutting.  When I hit the start button the machine moves away up in the z+ direction and I have to hit the stop button.  Can anyone tell me why or is there a setting that I have to change. Another thing is that when I push go the z the x and y move first and I want the z to move first how do I change this.

General Mach Discussion / Weird problems

« on: March 05, 2016, 08:27:05 PM »

I am new to cnc so bare with me please. I've had my machine for a little while  but I got away from it for a year. I fired up the computer and it wouldn't come on. It wound up the power supply was fried. Mite have been hit by lightning. I got that fixed and  install ed home and limit switches. I wired them with 18 gauge sheilded wire hooked in series. I sent all the axis to home which they activated and worked fine, so I shut down the machine for the day. The next day everything was at 000 so I moved to axis and re home again and the z moved to the +hit the home switch and stopped. Then the y move to the - and stopped along way from the switch.  The x did the same. So I retried by going to move the z in the - but it hit the home limit again. It winds up that the + automatically changed to - but nothing indicated this anywhere on any screen. The other axis were the same. 1 other problem is that the z dro is not changing  in either motion of the axis and all my of axis are off in calibration.  Can anyone  help me I'm  getting frustrated.
