Re: [Emc-users] looking to add inputs on Pico setup
I' slowly working on a USB pendant. All the data both directions will go over a virtual serial port and USB. I'm pretty sure you can buy a serial interface pendant, in fact that is how most of them work On Sun, Feb 23, 2020 at 7:26 AM Ed wrote: > Is there an easy way to add encoder inputs on a 4 axis Pico Systems > setup?

Re: [Emc-users] looking to add inputs on Pico setup
I used a USB pendant. Works with both MACH3 automatically and with LinuxCNC
using the
[XHC_HB04_CONFIG]
# specify layout = n for LIB:xhc-hb04-layout{n}.cfg files
layout = 2
# coords: specify upto 4 letters from set {x y z a b c u v w}
# coords: switch labels are xyza but any unique 4 letters
# from the set {xyxabcuvw) can be used (if the coord exists)
coords = x y z a
# lowpass settings:
# coef: slows rate of change of output, range: 0 < coef < 1
coefs = 1 1 1 1
# scale plus or minus, rotaries may require larger scale factor:
scales = 1 1 1 1
# jogmode normal(default) or vnormal or plus-minus
jogmode = normal
# sequence 1: 0.001,0.010,0.100,1.000 (mm-based machine)
# sequence 2: 0.001,0.005,0.010,0.020 (inch-based machine)
# sequence 3: 0.001,0.010,0.100
# sequence 4: 0.001,0.005,0.010,0.020,0.050,0.100
# sequence 5: 0.001,0.010,0.050,0.100,1.000
sequence = 2
# require_pendant = no: create xhc-hb04 hal pins when pendant not connecte
# at startup
require_pendant = yes
# inch_or_mm = in | mm
inch_or_mm = in
# mpg_accels: provision for reduced acceleration for manual mode jogging
mpg_accels = 2.5 2.5 2.5 12

Specifically adding a hand wheel and to select feed rate and spindle speed. No easy way to do that. On one of my machines I have no additional encoder counters (3 axes plus spindle encoder) so I ran it in through the general purpose I/O. Now, there are a couple other ways to go. One would be to add a PCI (or PCIe) parallel port, set it to input mode and you get 11 (I think) inputs. These would be plenty adequate for a jog pendant. Or, if you have enough I/O left, you can do like this : http://pico-systems.com/pendant.html There are links to some hal files and schematics that show how to do it with minimal I/O by multiplexing the selector switches. Using a few diodes, you can cut the I/O pins down to seven, and still have 7 selections plus 3 jog rates. I have XYZ plus feedrate override and spindle override on my selector.
