Well I first built my CNC back in '11 and ran it with Mach3 on XP, well doing my first circuit board got 95% done then the computer decided to die on me then 64 bit came along. So moving forward to today after trying a few control boards finally got one that works.

Now this board to my surprise only has 4 inputs and no socket to connect with the ground of my cnc, so getting my limits to work has been very troublesum to say the least and still no joy.

Anyway calibrated all the axis using my DMM over 2mm and got each axis to 0.01mm, did a few checks on the X axis and all appeared to be true. So made a gcode to drill some mounting holes and found 100mm was actually 102mm. So more calibration will be needed.

Now what made me give up today after running the CNC and stopping the code the X axis when I write Ggode just won't show up in the Mach3 screen did several reboots with no joy so not sure why it is doing this. Now when I do G01 Z 10 it shows when I do G01 X 100 no G01 X is shown.

Here is a bit more information about my CNC

Each stepper motor is driven by a DM556 micro stepper
The motion control board I bought from a Aussie seller Ncmaster and it uses BSMotion-V2.0
Each axis has ball screws and linear slides so no real backlash

Now my simple Gcode file

F250
G01 Z 5
G01 X 0

Now when I load the Gcode all I get is

F250
G01 Z 5
G01 X isn't shown at all and has problem has carried over from yesterday.

I have checked all the wiring and all is sound on the X axis and the DM556 leds are glowing green with no red led showing. So I do feel this problem is with Mach3 and not my CNC.

Hi Bryan,

You need a "carriage return" (ASCII CHR13) at the end of your GCode file. Just add the character  %  as a final line.

Thanks for that tip Tweakie it worked a treat and now when I edit my GCode file I just leave the % there, now going off memory when I used Mach3 back in the days of 32 bit there was a jog feature builtin to Mach3 but now I can't find it at all. I do feel the jog feature is a needed item as I can't see the point of having to make a small GCode file just move the axis to start a job.
