Mach4 General Discussion / Re: Setting zero

Thanks Tom.  That makes sense, just wanted to make sure I wasn't missing something somewhere.  I was expecting it to use the center of the bit at its origin, but my parts aren't coming out the right size.

Oppps,   I realized I posted in the wrong section.  I have Mach 3 not Mach 4.  I don't believe this screen is available in Mach 3?

Mach4 General Discussion / Setting zero

« on: October 27, 2023, 12:19:34 PM »

Hello,

Is there a setting in Mach 3 that tells the system to use the center of the bit rather than the outer edge when zeroing your X,Y,Z axis?
I've just installed a triple-edge finder with some code that finds the center of the hole and calculates the center of the bit.  I have been having some strange issues since installing this where my parts aren't coming out the correct size.  I'm still troubleshooting, but one thing I wasn't sure of is if the machine is trying to use the outer edge of the bit rather than the center?

General Mach Discussion / Cannot do g1 with zero feed rate, Block=G1 X0 Y0 Z0.5

Hello,

Im having an issue with a few files that I created in Fusion 360.  It seems to be related to the IJ setting in Machs General Setup window.

Im trying to run this code:

G90 G94 G91.1 G40 G49 G17
G20

M5

T2
G1 X0 Y0 Z0.5

The machine throw this error, Cannot do g1 with zero feed rate, Block=G1 X0 Y0 Z0.5
I have tried setting the Mach 3 to absolute, closing and reopening the file and inc and closing and reopening the file but still see the error either way.

Wouldnt the first line (G91.1) override the default in the match screen anyway? 

Thanks

General Mach Discussion / Start cycle just halts on start

« on: July 02, 2017, 09:07:52 PM »

Has anyone seen this?  This happens after cutting for a while.  I load a new gcode file, from the same model and when I hit start cycle, it doesn't start.  It might move down one or two lines, I'm not real sure about that, but it must be sending code to the buffer, because it looses its place and is hard to restart without re zeroing everything.  I'm new to cnc, so I'm not the best at troubleshooting, but I don't think it is noise in the lines or snything like that since it always only happens at the start of a cycle.  Maybe the controller is overheating?  It's a Gecko 540.  Any advice would be appreciated. 
Thanks
