Thanks Tweakie, chasing up the electrician for the filter.
I have been running large files on the cnc to basically become familiar with motor tuning, speeds, positions on the table. These files are used on my large ART CNC router.
I am coming up with an intermittant problem where the program stops running and it comes up with message "radius to end of arc differs from radius to start" I know the file is ok as I have already cut this file on the large machine. Why would this be coming up especially when I could run this file again and it wouldn't faulter. It also does it with other files as well

Regards Humbuk

Hi, I have the router running nc files and homing all ok. I have one problem, I have noticed that a power point or light swiitch when turned of or on is sending a pulse to the cnc and throwing the safety /stop button. All micro homing switch leads are earthed. any ideas to stop this please.
Also I have set up a tool depth set micro , it sits about 200mm in from the end and side of the table and is clear of the machining area. How do I tell mach 3 where this micro switch mechanism is, set the tool depth (surface of the work piece) and then get the XYZ axis  to return to the zero point to start work. I am using Enroute pro for all my toolpathing which sets my tool at top of surface.
I now run all my homing and slave homing switches on 2 inputs on the breakout board, so I now have 2 connections free 1 being for the tool depth micro
Best regards Humbuk

Hi Hood, back on deck with finishing my router. The set up for homing and jogging in the correct direction is now fine. 1 have a question regarding home switches. currently I use a 5 axis break out board, 1 connection each for 4 axis incl slave , 1 for spindle on off. Can I run the homing switches in series and connect to just 1  board connection so that I can also set up a tool material height micro switch. The Mach 3 simple setup says yes for a 3 axis setup, but it doesnt refer to a 3 axis with fourth slave axis
Regards Humbuk

Hi Hood,I will check out the Led's on the DRO'S, havent noticed that one. With the other problem, do I set to run in the correct direction for normal operation, and then reverse the homing on the limits and home page, in other words is there a definate procedure to follow.

Have recently completed my router with 2 steppers on the X axis. One moter wired in reverse (a axis) and slaved to X. Homing switches are set up on each individual axis.
Problem (1) is that machine homes on every axis but does not reverse off each switch, and problem (2)is after homing the x axis it will not run in the correct direction when jogged by the arrowed keys. After I have reversed the X axis motors to allow jogging in the correct direction the x axis will then not Home in the correct direction.  Hope someone can help Thanks Humbuk
