General Mach Discussion / Re: Parallel Port to Ethernet?
« on: April 16, 2019, 11:05:34 AM »
I think I found what I'm looking for.  The "UC400ETH ETHERNET Motion Controller" looks like it will work.

Thanks.

General Mach Discussion / Parallel Port to Ethernet?
« on: April 16, 2019, 09:35:27 AM »
Hi, I'm am using Mach3 with a stepper controller board using the parallel port and it works great.  I'd like to be able to control the controller board from 10 meters away.  I was thinking about using some sort of ethernet to parallel port module.  Ethernet would be connected to the laptop and parallel port to the stepper controller.  Anyone have experience with this?  Can you recommend a converter to do this?  I want to stay away from changing the controller board.

Would a "TP-Link TL-PS110P" or "StarTech.com 1-Port 10/100 mbps Ethernet Parallel Network Print Server" work?

Thanks,
Denis.

G-Code, CAD, and CAM discussions / Re: 4th Axis Problem

Ok, it looks like when doing a G01, A-axis can only go in the forwards direction.  Anyone else see this?

G00 X1
G00 A1
G00 X0
G01 A0 (this goes from 1 to 359 to 0)

I'm not getting it.  I must have something in my Mach3 profile that is set incorrectly.  Check out the GCode below. A follows X except when A is supposed to go to 1, it goes there the long way 2->360->1.  It's like I can only go in the positive direction with A.  I have "Rot 360 rollover" and "Ang Short Rot on A0" set in my general config.

G01 A1 (this goes from 2 to 359 to 1)

It works if I use a sub routine and end the cycle.  That's my work around for now.

G0 X0.3
G0 A356
M98 P1000

It seems to have something to do with the "Rot 360 rollover" and "Ang Short Rot on G0" options in general config (under Rotational).  When I enable any of these, the rotation axis doesn't stop exactly on the commanded spot, but only after the G81 command.  Anyone experience this?  I've tried reducing the accel and speed of the 4th axis, but nothing seems to fix it.

G-Code, CAD, and CAM discussions / G81 Problem with rotary stopping exact
« on: February 06, 2019, 03:33:23 PM »
Hi, I'm new to Mach3, but I've done GCode before.  I'm having trouble with using G81 to drill many holes on my rotary axis.  It drills the first hole correct, but while moving to the next hole position, it travels too far.  This happens offline too.  The example below drills a hole at A356, then goes to A358.14 and increases from there.  X axis starts to very slowly move as well.  Strange!

G0 X0.3
G0 A356
G81 R0.25 X-0.5
A358
A0
A4
G80
G0 A0

If I replace the G81 with G0 A358 G1 X-0.5, it will stop exactly on 358.
What am I doing wrong?
