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

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.

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

General Mach Discussion / Mach3 w/uc100 estop won't reset

« on: February 12, 2018, 09:36:49 PM »

Hi brand new user
I've set all ports and pins correctly including estop to 15. Both lights are on on the uc100 as they should be. I loaded both Mach 3 and uc100 with ucx00 setup. I'm running Mach 3 in demo for now. As far as I know all was done right. When I launch Mach 3 both lights come on on the uc100. When I click on e stop reset nothing happens, it stays on. History shows this

Sun - 19:01:01 ---Program Startup
Sun - 19:01:04 ---ReConfiguration Estop.
Sun - 19:01:16 ---command killed due to buffer error.

What do I have set wrong? Running Windows 7 64 on an AMD A8 @1.90 gh and 8 gb of ram. Any help? CNCDrive support said it is a conflict in Mach3 of course 

Any help? Thanks
