Ian,

Even if his system is not that well matched don't you think he should still be able to achieve better than 50 rpm ??

Tangent Corner / An Optical Illusion.

Obviously the camera shutter plays an essential part in creating the illusion here but I found it interesting nonetheless.

Hi Stuart,

The fact that you cannot use P2,P3 is an indication that something is wrong there.
One difficulty that has cropped up a few times recently is that most newer PC parallel ports have changed from the 5 volt TTL standard to the 3.3 volt TTL standard and some breakout boards will still only reliably work with the 5 volt signals.

Stuart,

I take it you have set up each of your steppers for optimum Velocity (reduced by some 20% - 30% for reliability) and Acceleration ??

Hey buddy, don't do yourself down, we have all been there - in my case many times.

There are a number of test programs which are below the 500 line limit here http://www.machsupport.com/forum/index.php/topic,18345.0.html these may be helpful in setting up and trying out your machine etc.

I have high degree of intelligence and speed problem solving.

Looks like you joined the right forum buddy, all the members here have a high degree of intelligence and speed problem solving, I think you will fit in well.

General Mach Discussion / Re: Tool Zeroing

« on: November 28, 2011, 11:48:11 AM »

Hi NormB,

If you are lucky and the tool is already at GND potential then you only need the one lead, connected to the copper plate. This lead is connected to any spare input and configured within Mach as the Probe. There are numerous macro's for the auto tool zero button and you just choose which one best suits you.

If it is any help, the way I have implemented it is shown in the bottom half of this page. http://www.cooperman.talktalk.net/files/17.htm
