Understood, the pin identifications for the serial wiring to the computer will be the same for all these models (hopefully) so that should be one problem solved.

Les,

Are you saying that the Dell corrupts the GCode program with the first 150 lines or so being correct and then the remainder being corrupted and incorrect ?

Exodus,

Just one point that's important - Check that your existing steppers can be operated bipolar (that the have 4, 6 or 8 wires and NOT 5). The cheap Chinese boards are almost all designed for bipolar operation of steppers.

This attachment  is pretty typical of a single board instructions and may be of interest to you.

Good fortune with your project.

Had second thoughts about this one and deleted my earlier post.

One of the cheap, Chinese, stepper control boards would work and if you were careful in the way it was fitted then either the original or the new options could be used, as required. Something like this  http://cgi.ebay.co.uk/3-Axis-12-36V-3A-CNC-Stepper-Motor-Driver-TB6560-NEW-/250703238018?pt=UK_BOI_Industrial_Automation_Control_ET&hash=item3a5f13d382

Exodus,

I don't think there is any modification necessary. Just draw your required stencil and send it to the machine to cut. If I am missing something here perhaps you could elaborate.

General Mach Discussion / Re: mach3 stop on screen

« on: September 24, 2010, 07:35:20 AM »

Is it possible to add a feed hold button that does the same as using the mouse and clicking the feed hold on the screen?
or somehow using a key board stroke.

Am I missing something here guys ?.

Whats wrong with just using the space bar for feed hold ?.

Keith,

Sounds like it could be an electrical noise problem. You could try re-routing your cables clear of your monitor and separating the mains wiring runs from the signal wiring runs.

Hi PJ,

I think we are going round in circles here.

The Astrosyn 402 spec says that it's inputs are TTL compatible (in my book, that's the 5V standard) it does not specifically state that it complies with the 3.3 Volt standard. As I said earlier 3.3 Volt may not be enough to operate some opto-isolators, at least not reliably and I think you should check this point with Astrosyn before proceeding further and looking for problems that may not exist.

You could try using a PC with 5 Volt parallel port or fit a PCI parallel port card with 5 Volt output, either of these two options may solve the problem.

Tweakie.

nb. You are correct - the pulse is associated with step within Mach.
