Hello,

your code will only work, if you are in incremental mode (G91), not if you are in absolute (G90)

Thanks to you both, to prove that I am a noob where do I check and change that? I've seen it but don't remember where. Also is one better for common usage.

G-Code, CAD, and CAM discussions / Noob G Code question

« on: October 12, 2020, 11:51:21 PM »

So I am brand new to CNC and after a 2.5 year battle over receiving a machine that was being built for me and then receiving an incomplete pile of pieces I have my machine together and moving. I have no experience with G Code but love to learn new things. Tonight I tested movement with code for the first time. I wrote a simple code to start in the middle of a square, move out, move around and back to the center just moving air. Here is the code

%        (1)
G01
F50
Y-2
X2       (5)
Y4
X-4
Y-4
X2
Y2       (10)
%

The machine ran blocks 3-8 exactly as it should but it moved block 9. 4 inches and block 10. 4 inches. So it didn't end up back at center but rather at the back right corner. I ran it many times with the same result. Running Mach 3 with motors calibrated and tuned. Do I have a setting wrong in Mach, or am I not understanding the code or what? I know this seems ridiculously simple to most, but a guys gotta start somewhere. Even at 64. Thanks for your help

General Mach Discussion / Axis slaving question

« on: April 30, 2020, 10:22:36 AM »

Sorry if this has been discussed. I found info on slaving, I need to slave axis A to axis Y but I have a rack and pinion system not a ball screw system so I need to reverse the rotation of one of the motors. I'm a newb to Mach3 and to CNC so is this possible? If so can someone kindly lead me step by step? If not, what are my options? Thanks in advance.

Yes that is it, thank you. I couldn't get search to work. I will PM Dan to see where development is at currently. Thanks again.

I was watching the development of this product here on the forum for a dealer friend and now can't seem to find it. I don't remember who was doing it. Anyone know where it went.

Thanks
