General Mach Discussion / Still stymied by my LPTs
« on: January 13, 2011, 02:35:00 PM »
I had been using my Mach3, WINXP, Zylotex, Sherline 5400 mill setup for some time when, just after Christmas, I started having harddrive problems.  I've switched to another HD, but can't get the setup working again, apparently because of LPT problems.  I recall I had problems there initially, too.

I'm using a Rosewill PCI board with 2 additional PPs.

Checking Device Manager, I see LPT3 as being at 0xDD00, and set Mach3 Port1 equal to that value (enabled).  Incidentally, when I change the port address in Ports and Pins, I have to force the Apply button to become active.  Subsequent checking confirms the new address.

Motor Outputs are enabled for X, Y and Z.  With the cable connected, I get DRO values to change, but no motor movement.

Checking with a multimeter, I see unchanging +4.90v on pins 2 through 7, which are the assigned Dir and Step pins.

I've run DriverTest, and get Excelllent results.

What else shall I try?

General Mach Discussion / Error msg loading G-code
« on: December 15, 2010, 09:01:24 AM »
Pardon the newbie question, but I can't figure out why I get the error msg, "Tool Radius greater than approachLine 1", when I load this G-code:

G91.1  G17  G41 P0.250 F10
G1 Z1.0000
M30

I presume I'm being warned of a collision problem, but I can't figure out why.

TIA

Charley
