Show"N"Tell ( Your Machines) / Home Made Wireless Tormach Passive Touch Probe

« on: July 06, 2015, 05:47:36 PM »

probably like most I cant afford one of these expensive wireless tormach or renishaw probes, so I made my own (with the help of a friend)

I purchased one of these

http://www.tormach.com/product_tts_passive_probe.html

its comes with a long cable which you need to hard wire into you control system to work, it works great but the cable is very annoying. so a friend made a IR sender and receiver that can connect to any control system. I use a pmdx126 and the setup for a probe is dead easy. connect the probe directly to the board and all it does it act as a switch, so mach3 knows when its been triggered or not.

the receiver board just uses a relay as the switch so it can connect to any control board.

heres a video of the setup in action, its a very rough setup just to test proof of concept. next I plan to integrate properly

err its step/dir

I don't have a link to the drive card sorry.

but it gets signal from a v4 spindle board.

so it goes ESS to pmdx126 to V4 spindle board to sprint drive card to servo motor

ive got a sem servo motor controlled by a sprint drive board. ive got a pmdx-126 main board with ESS to connect to laptop

I just want to make sure im not missing a little tick box or something in mach

for example in ports and pins in relay control, are the m3 and m4 command output both suppose to be the same output? mine are both 1

as far as I can tell my machine is wired up correctly for CW and CCW but I cant get it to do it.

no matter if I do an m3 or m4 its always cw.

are there any special setting I need to tweak in mach to get ccw to work?

cheers

General Mach Discussion / Probe + PMDX126 + electronics help

« on: March 11, 2015, 05:16:14 PM »

so my cnc runs mach3 and it uses the pmdx-126 board.

I have a tormach passive probe, which when hard wired in works perfectly from j15 and gnd on the pmdx.

ive had a very helpful chap made an IR sender and receive for me in an attempt to turn the wired probe into a wireless probe, but were having problems with mach3 and the IR receiver working correctly.

when the probe is hard wired in, all you do is shorty j15 to gnd

we are now switching 5v on and off

are there settings in mach3 I can adjust to get my setup to work?

I want to store all my machining files on dropbox and then load them straight into mach3 from there. but it would seem mach3 doesn't work with dropbox

is there a way to get mach3 to work with dropbox?

dear all,

I was reading this -

and point 5 got me thinking, is there no way in mach3/4 to improve accuracy with regards to this?
