General Mach Discussion / No Manual stepper control
« on: February 28, 2016, 01:03:32 PM »
Out of nowhere, I've lost manual control to run stepper motors. Diagnostic screen shows Output 2 in red.  It's been a while since I had anything go wrong. Can anyone suggest how I should start to fix my problem?
Thanks

General Mach Discussion / How to add LED's to Control Panel for Jog Modes.
« on: September 30, 2010, 05:21:32 PM »
Hi All,
I added pushbuttons to my control panel for Jog Cont. and Jog Step. Now I would like to add leds so I know which is active. I wired an led with a 220 ohm resister from 5vdc source to BOB2  pin1. Then in Ports & Pins/Output/, I choose  Output2 and entered 2 for ports, and 1 for pins, and choose Active low. Wrote a brain with Jog Cont Led as input, to Pass Signal/No Operation to Output2. The brains switches on when I'm in JogCont, but the led always stays lit. What am I doing wrong?

PoKeys / PoKeys55 and MPG Pendant
« on: July 13, 2010, 05:24:50 PM »
Hi All,

I built a simple pendant with (2) three position rotaty switches for Axis select and Step select. I set them up (on PoKeys) as digital inputs on pins 6 thru 11. I have a single pushbutton, pin 5, selecting MPG Jog mode.  These all work fine as expected. I have an MPG wired up to my Pokeys pin 1 and 2.  I set up both the Encoder 1 and MPG #1 in 'Ports & Pins' to Port 10, Pins 1 for A and 2 for B. When I rotate the MPG, I get cycling on the 'IO Status' screen and the 'Encoder RAW Value' screen, but no physical axis cycling. I tried enabling "Enable Fast Encodors' Pins 2-3, 4-5 and 15-16' to no avail. Can anyone help?

General Mach Discussion / Enternal E-STOP Leds
« on: June 21, 2010, 01:38:04 PM »
Hi All!
On my Cntrl Pnl, I mounted a MACH3 RESET switch along with two red leds (one on each side of switch). I got the Mach3 Reset switch to work (OEM 1021), but I can't get the red leds to go on (or blink) as the "Program Run Alt-1" screen red leds do (when the E-stop is triggered).  Any help would be appreciated.

General Mach Discussion / Add Cont-Step-MPG Leds to Cntrl Pnl.
« on: June 05, 2010, 04:29:20 PM »
Hi All,
I put a momentary switch (OEM Code 245) on my control panel to toggle thru Cont, Step, MPG modes.  I would like to add a LED for each position so I know where I am after a toggle, but don't know how.   I think the OEMLeds are 14, 15, 57.  All help would be appreciated.

General Mach Discussion / Why doesn't OEMCode 307 jog?
« on: May 17, 2010, 03:23:17 PM »
Hi All,
I want to add some switches to my control panel to jog X, Y, & Z axis similar to the lower buttons in the (tab) MPG Mode screen. Using OEMCode 307 for X+, when I push my X+ switch, the X stepper runs continuously and doesn't stop when I release the button. The Jog Mode in in Cont. Can anyone explain what I am doing wrong?.

General Mach Discussion / Input or output
« on: May 11, 2010, 03:35:18 PM »
Hi All,
I'm trying to get an external switch to trigger OEMCode 327 (Select MPG Jog Mode). Should I be using an input or output?

Hi All,

I added a RESET (Program Run screen) pushbutton on my control panel enabling me to RESET from my panel instead of my PC.  I now would like to add an led to duplicate the status of the RESET led. Can anyone help?

General Mach Discussion / Need HELP with Mach3 Setup
« on: January 13, 2009, 12:58:51 PM »
I built a cnc router. The Control console uses (3) KL-4030 Drivers to drive (3) KL23H286-20-8B motors, a CNC4PC C10 Parallel Port Interface card and using Mach3 software. I built a 555 square wave generator  to test out the wiring.  I insert the square wave (800Hz @ 5v p-p) onto pin 2; 4; and 6 and all motors run fine in both directions. My problem is getting Mach3 to do the same. I watched the configuration video, followed all instructions, and all seems to be in order. When I go to Motor Tuning, I choose axis, insert proper step value ( even improper step value) play with Accel & Velocity, save axis settings then press up or down keyboard key. Sometimes I get motion sometimes I don't. I can't get continuous running. Same on all axis'.  Tried using Mach3 from 2 different computers to no avail. Scope shows input to x-step (pin 2) about 6us pulse 5vp-p (555 is much longer pulse). I know it must be a setup fluke but I can't find it. I took some pics of my setup. I'll try to post them if I can. If not, you can PM me, I'll be happy to forward you a copy. It could help to clarify things. Any and all help would be appreciated. Thanks gentlemen.
