Share Your GCode / How to speed up simple G Code
« on: February 04, 2013, 04:52:23 PM »
Here is my simple G code for a tying machine-M3, M7 and M8 run solenoids.
X and Y are servos for a wire feed and a wire twister -
The cycle takes about 3.5 Seconds - I need to run in 2.25 Seconds and most of the time seems to be in the execution between comands and not the servo speeds.
Anyone's help would be worth some money

General Mach Discussion / Input pins & Auto load a program
« on: December 28, 2012, 09:28:32 PM »
I need all input pins (without ESTOP) I don't need the ESTOP
I give the Estop an unused pin and when loading Mach3 the ESTOP error notice comes on.
How can I get rid of this error message ?
This is for a commercial machine so can't have the error message.

Also is there a way to load Mach3 and have a program auto load?

General Mach Discussion / How to Jog X+ with an external switch
« on: December 11, 2012, 01:54:24 AM »
Is there a way to jog X+ (Right arrow) from an external switch without a keyboard emulator?

Is there an OEM code for that or is this a dumb question?

I am running 2 screen functions with external switches, so OEM codes work there.

Could someone explain the EMULATED input check box on Input pins- How that works -  could use 2 more external switches - I'm Poor at electronics

Thanks  Jack Hoffa

General Mach Discussion / LED for in-position (servo active)
« on: November 19, 2012, 02:41:26 PM »
I am running mach 3 with 2 servos and Gechos

I need to have an external LED that turns on when the servo motor is in-Position (ACtive or what the proper title is.) Does any know of an circuit that would do this.
I talked to a Gechodrive engineer and he said there was no way to connect to the Gecho to do this.

I am not good at electronics and need help-
this is very important to my current project.

General Mach Discussion / run small program with a switch
« on: October 16, 2012, 07:15:40 PM »
This is probably old stuff
I need to run a short program from a switch (with the main program loaded)
I already run the main program from another  switch.

G91G0X 3.5 (feeds 3.5in of wire)
M7 (Cuts wire with a Solenoid)
M9 (Releases Cut Solenoid)

We are making a Twist Tie machine w/2 servos - Runs on Mach 3 - works great - have a patent

Is this do-able ?

Also am going to need some help with Screen Design soon - Like to hear from anyone interested with price

SmoothStepper USB / Motors cross talk on COMPAQ Laptop Win 7
« on: February 15, 2012, 05:46:52 PM »
I,ve been going nuts for a couple days - trying to get SS to run with my COMPAQ laptop with win7 PRO  ( and Gechos)
The 2 Motors latch to each other. One drives both etc.  Even with one of the motors not enabled it drives both.  I slowed them down and set  long accel/dec and they would sinc with the gechos, but never run independently,???
I loaded the latest Mach3 and SS on one of my XP's and they worked perfectly.
So is it Win7, or the Laptop.--I tried many grounding methods.

Where to start would be greatly appreciated

I need to start a program from an exernal switch.  Sorry if this is old stuff.  Do I need keyboard emulator, or ???
I am working on a comercial tying machine using Mach3 software, it works quite well.
