FAQs / Re: Migrating Machine - Parallel Port Will Not Run

« on: September 05, 2010, 09:20:27 AM »

i have had computers that wont run one cnc machine and yet they will run another, and it was down to the epp setting. Another possible cause could be a lack of correct ground connections. What make are the comps.?

For the benefit of others, what was the problem?

yes, what cured the problem, and what was it eventually.

You say they work fine and stop the machine.  That implies that they are properly enabled as "Limit" switches.  However, I believe, if they are not enabled as "Home" switches, you will see no motion when you press "Ref All".

On the Ports and Pins -> Input Signals page I mentioned before.  Are the "X Home", "Y Home" and "Z Home" enabled with valid Port and Pin numbers?

Have you checked this, and a reload of mach may help but make sure you either save the xml or know the settings.

adding a 0.1uf ceramic cap to ground on all your inputs seems to cure this odd creeping on the axis.

ok i've just done a boxford 240 tcl, and my gemini is this way

1. no connection
2. 0-8v
3. connected to 9, connected to contacter (thin grey/black wire)
4. no connection
5. no connection
6. no connection
7. common of 0-8v, connected to 8, ground
8. connected to 7 and 10
9. connected to 3, connected to safety interlock (thick red wire)
10. connected to 8
11. no connection
12. no connection

It looks like the link between 3 and 9 is an overide for the safety interlock that should open this connection between the grey/black wire and the thick red wire, disabling the drive
