dakmonf,

If it's any consolation I think we have all been there (in my case more than once).

General Mach Discussion / Re: Scan 3D in mach3

The Impact / Laser plugin that I use for laser engraving was developed from a Mach probing routine. The source code for this plugin is available from the plugin’s page and if you take a look at the code you will see that it is already two thirds of the way towards the probing routine shown in the video clip.
OK you would need to know a little C++ but it would not be rocket science for you to adapt this plugin to suit your own needs if you are determined enough.

Just a thought.

LazyCam (Beta) / Re: LC never produces valid GCode
« on: July 19, 2011, 02:55:18 AM »
LC has more little quirks than I could count, perhaps that's why it remained a beta.
You need to practice at it, experiment a bit, and it will work and produce very good results.

I just ran your example through LC and depth data seems OK.

I will wait to hear how you get on with the VFD - Good fortune changing any settings without the manual.  :-\

(I am really not sure I could program my VFD without the manual - the menu is quite extensive and contains stuff that I can only guess as to what it does).

General Mach Discussion / Re: Mach doing it again
« on: July 19, 2011, 02:15:00 AM »
Sounds like it could be Direction signal problems.

If the direction signal is not present for a particular axis or is shorted high or low then that axis will only move in one direction.
If the PC parallel port output is only 3.3Volt on a direction pin and the BoB expects to see a 5Volt signals then again the axis may only move in the one direction.

Perhaps check your wiring and the pp output voltage  ;)

To add to the last posting..

Did you change any of these settings ?

Hi Cosha,

This thread has gone very quiet lately - How are you getting on with your rebuild ?  :)

I understand your frustration but you have to be more precise here if we are to be of any help.

Please read my previous post again - You said the spindle was working and you changed some settings then it didn't work.
What settings did you change exactly ?

General Mach Discussion / Re: Stepper Motor problem
« on: July 17, 2011, 11:03:19 AM »
Steppers use a Step signal and a Direction signal. The Direction signal is either high (+5V) for one direction of rotation or low (0V) for the other direction. If the Direction signal is missing or shorted then the the motor will only run in one direction.
It is also possible to have a motor with one wire not connected behave in this manner. With everything switched off check all your electrical connections thoroughly.

Hope this helps.

I have 5mm pitch ballscrews, 200 step motors @ 1/8 microstep and my steps per mm are set at 320.  ;D
You are spot-on Rene.
