PoKeys / Possible glitch in MACH3 plugin, with LCD panel attached.

« on: October 23, 2013, 10:34:58 AM »

Dear All.
Have a PoKeys56U, hooked up to a Parrallel 2x16 LCD panel. (And nothing else)

Line 1, Column 1: Does not seem to be updated when running/configured via MACH3 plugin.

The char is kept in the same state, regardless of what is input, either User input or DRO input.

Have checked with the Pokeys software 'LCD test' and here it updates just fine.

Can anybody confirm this ?

Best Regards, Bo Andersen.

PoKeys / Re: How to setup rotary encoder as MPG ?

« on: October 23, 2013, 01:36:52 AM »

Hi Matevz.

No, I alreadu have the MPG as you link to.
It's more to control the Feed, Jog, Spindle, MPG-Jog speeds.
The "real" panels have 3-4 smaller knobs for adjusting the override of above speeds.

But I'm unsure if this is done via:
- Rotary encoders (grey-bit) Require 2 inputs, and rather precise in positioning.
- Pot meters ( 0-3.3V) Require only one input, but it "jumps" in the setting, and not easy to get back to precise 0% override.
- Rotary switch (1 pole, 12 posistions) This requires 12 inputs :-/

I was planning on using the Rotary encoder, but i can only find some with 20-24 ppr, which results in 5 turns to get 100% :-/

Any suggestions, perhaps there is a trick to get the analog one not to "jump" in voltage.

Best Regards, Bo Andersen.

Hi.

Great, I would never have guessed to enable the MPG, without setting some ports/pins also.
Anyway, it works.

Apparently I can set a keyboard shortcut Pin1 = "Shift" key, and this setting is kept when the MACH3 boots up with the PoKeys-MACH3 plugin.
I.e. I can enable the "Rapid Jog override" perhaps not in the best possible way, but it gets the job done.

Off-topic: Now where to find 100ppr encoderes ? Those on eBay is either those big, fancy and $$$ alu-wheels, or then they only have 20-24ppr ?
To be used for setting: Spindle speed, jog, speed, feed etc.

PoKeys / How to setup rotary encoder as MPG ?

« on: October 14, 2013, 11:11:18 PM »

Dear all.
PoKeys 56U, MACH3 plugin, all works like a charm.
Not using the PulseEngine, this runs via. 2x Parallel Ports

I have setup a rotary encoder on pins 1+2, and the encoder function works.
Have tried on different DROs

1) Where/How do I set it to control movement of the selected Axis (MPG mode)
Right now I can only select "Step" and "Cont." jog modes and not "MPG"

2) Is there a DoButton function that acts as the "Shift key" aka.  enable Rapid Jog override ?

Best Regards, Bo Andersen.

Great, thanks.
I will look into Screen Designer Software.

General Mach Discussion / How to edit/add keyboard shortcuts for "Button Scripts" ?

« on: September 29, 2013, 03:10:00 PM »

Dear Forum.
I'm running the Big-Tex Blue Screen set.
Where some customized appears: "Initial Zero Setup" and "Tool change zero"
I would like to add some keyboard shortcuts for those as minimum, but also for other function.

Is that possible ? and how do i get started ?

Further I'm looking at the PoKeys56U, the idea is to have a custom controlbox wired to PoKeys, and run some of the scripts.
Will I need above shortcuts be needed for that, or is there a "DoButton" command for the scripts ?

Best Regards, Bo Andersen.

From what I read. When you close the circuit you apply +5V to the input pin of your BOB ?
Many BOB input pins must have the input pin Grounded (0V) to work.

*Face-palm*
Of course it does. Only checked the tool path, in MACH 3 and I was tricked to perceive it as a rounded corner.
Thanks for a quick response.

Had same problem with my E-Stop, while I build the individual parts everything was OK. But when the cables were put together (motorcables, E-stop, switches etc.)
The noise inducted into the E-Stop cable caused it to trip.

Had to build a insulation circuit with optoisolater supplied from a seperate 24VDC PSU, now it works as intended.

G-Code, CAD, and CAM discussions / G41 and profiling gives rounded corners with "Exact stop" ?

« on: July 02, 2013, 03:05:33 PM »

Hi All.
Rather newbie to Mach3, and G-code.

Hand coded below:
Idea is to profile a 50x50 square, using climb mill, and G41 tool offset.
While doing so the toolpath is correct but rounds the corner with same Radius as the cutter.
Have tried:
Change settings to "Exact stop"
Add G61 to the init code
all gives rounded corners ?

If i change tool cutter radius to 0, I get sharp corners.

Code: [Select]

M06 T01 (Tool change #1)
G41 P5 (Left tool compensation, Radius = 5)
M03 s27000 M08 (SPINDLE AND FLOOD ON)
G00 x-5.0 y0.0 z0.0
G01 X0.0 F500.0
Z-1.0
Y50.0
x50.0
Y0.0
X0.0
G00 Z50.0
G40

M00

Where did I go wrong ?
Best Regards, Bo Andersen.
