General Mach Discussion / Mach2 profiling
« on: November 21, 2007, 04:08:34 AM »
Hi there.

I am using Mach2 software to run a file that has been output from Rhino CAM to machine a surface profile with a flat on the top and a downward curved lip with a 1mm slot mill. On the top of this surface are a number of regions that the machine has to cut around. The machine seems to start on the curved lip and work up gradually until the first region to cut round is reached. It then works its way around one side and then lifts the tool to do the other side. however, although the display shows the Z value to be the same as before it lifted, there is a definite step after touch down. This then remains for the rest of the operation irrespective of the number of additional features that it has to cut round and lift off for. On checking, it appears that the machine is doing the curved lip with an offset, which it then ignores when it reaches the first tool lift off in the program. Thereafter, it follows the correct path.

I know there is no backlash problem with the machine and the simulation on both Rhino 3D and the G code simulator generate the correct profile. Is there an offset somewhere in Mach 2 that is causing this problem? The file has been generated with the following Gcodes: G21, G0, G17, G40, G80, G90, G61, and G43 and G01.

Any help would be gratefully received as this is driving me mad at the moment.

Thanks in anticipation Mark Humphrys

G-Code, CAD, and CAM discussions / Mach2 Emergency Stop
« on: August 19, 2006, 08:02:33 AM »
I have been using Mach2 in conjunction with Windows XP and previously 2000 and I am having problems with the system going into emergency stop mode at random intervals. I then have to edit the G code to start where it failed again. I have therefore just downloaded Mach3, having been told it is more stable. However, this has brought up two new problems.

Firstly it doesn't recognise G43 and secondly, despite having installed it properly including the little routine to manually install the driver, I can't get it to drive the machine at all.

Has anybody else had this problem and if so what course of action could you recommend.

Thanks in anticipation.
