General Mach Discussion / Re: Z coordinate shifts randomly when running various gcodes

Do you use a Zero Tool set? I had a problem like this awhile back on my Bridgeport.

Thanks that's exactly what I wanted!

Hood, will I have to add F30 everytime I start up Mach or do I change it in my XML file?

General Mach Discussion / Changing FRO

Is there a way to change the default FRO from 6IPM to something else? I know I can enter it manually, but I would like to have something like 30IPM load up every time that I start up Mach3.

General Mach Discussion / Hitachi L100 and Mach3

« on: February 29, 2012, 08:40:34 PM »

I have a FlexiCam router that is running Mach3, a Sound Logic BOB and Spindle control board. I haven't been able to find an XML file for the Spindle control board, but I did manage to get the board working by setting up the pin configurations. What I'm having problems with is getting my VFD to run from the 0-10VDC. The spindle will turn on, and depending on the settings that I have in the VFD it will run at full speed, but when I send anything less than 10VDC the spindle runs extremely slow. I have tried resetting the VFD to the original settings, but this hasn't helped. I know I'm probably reading something wrong, but I have tried about every setting in the VFD and haven't made any progress. One other I noticed is that I can not change the spindle speed from the Mach screenset by using the + or - buttons. Can anyone tell me what their Function Codes A_03 thru A_15 are set at? Thanks in advance, Ron

I can try that, but I haven't had this problem on my BP using a different program. This router is new to me and I've just set it up, I'm pretty sure that I do not have my settings optimized.

General Mach Discussion / Mach3 and Cutting a Circle

« on: July 26, 2011, 11:09:11 PM »

I'm trying to cut a circle and it's not coming out a smooth circle. I did a search of the forum and it looks like most of the time it's backlash causing the problem. I don't think that's my problem here. I believe it's my motor tuning, I can hear the axis not running smoothly. I'm not really sure where I should have my velocity, acceleration, step pulse and direction pulses set to. I can attach an XML file tomorrow if needed.

General Mach Discussion / Re: How to wire proximity switches

The info presented in this document may be of interest to you.  http://cnc4pc.com/Tech_Docs/C10R10_USER_MANUAL_V2.pdf

You need to establish the voltage and if they are NPN or PNP. If this information can't be determined then it may be wise to replace then with new parts of known specification.

Tweakie.

I think most proximity switches can handle 12 volts (think I read that somewhere). There must be a way to test the switch to see if it's NPN or PNP? 8 switches at $75 each isn't going to happen, must be a way to try and wire up one switch as a NPN and try it, if it doesn't work then it must be PNP?

I have a FlexiCam table router that I need to wire up the proximity switches. They are three wire, Blue, Brown and Black. I'm not too sure which wire is the positive and which one is the signal wire. Also I don't know how much clearance there should be between the switch and the contact strip.

I had two printer cables hooked together, apparently one of them was causing the problem.
