Parallel Port breakout boards, motherboards, and dedicated accessories / PMDX-126, PMDX-107, ESS - ATC query - pneumatic solenoid valves

« on: December 13, 2020, 06:45:40 PM »

Hi all,

Now got my machine up and running minus the ATC.  I have been swapping my tooling out manually .  I have been looking at the setup, basically there are a number of solenoids.  Thus, I believe I know the ladder diagram of the actual tool changeover steps but my issues are:-

1.  How do I go about connecting these solenoids upto the the PMDX-126?  The solenoids will obviously be outputs but there are also some inputs, prior to the next solenoid firing.
2.  How do I write a basic step/ladder program so I fire the write solenoids at the right time that Mach4 can understand.

Photo attached shows the solenoids on the left.

Hope my query makes some sense.

Parallel Port breakout boards, motherboards, and dedicated accessories / PMDX-126, PMDX-107, ESS and spindle control using opto isolator

« on: November 16, 2020, 06:17:16 PM »

Hi all,

I havent been on the forum for a while, I stopped working on my CNC conversion but with all the spare time I have been reinvigorated. 

Basically, I have a small CNC mill that I have been converting for using Mach4.  I have the machine running for the most part but have some queries I am hoping the brainy people can help with :)


Hardware/software:-
Boxford - vmc190
ESS Smoothstepper
PMDX-126
PMDX-107
Sprint 1220 speed controller
Mach 4

Settings are basically:-

PMDX-126
SW1
1 - closed
2 - closed
3 - closed
4 - closed
5 - closed
6 - closed
7 - open  (as I have PMDX-107 card installed)
8 - closed

I am not using either K1 or K2 relays at the moment.

PMDX-107
SW1
1 - off
2 - off
3 - on
4 - off
5 - off
6 - on

I have my motor controller connected to Fwd/Run, COM, Aref and obviously Aout and Agnd (0 - 10vdc).

I have all axis running, and my spindle runs (currently only one direction), however I have the following queries

1.  Is it best to use K1 relay for spindle?  If so how would I incorporate this with the 107 board?
2.  My spindle motor should run backwards.  What have I missed in setup to allow for this?
3. The spindle has a RS-306-061 opto isolator switch on it.  Can I connect this into my system?  I assume this would be back into PMDX-126 board. 

Thanks for any help/direction on the above.

Hope all are keeping safe and giving youselves lots to tinker with :)

Parallel Port breakout boards, motherboards, and dedicated accessories / PMDX-126 - How to connect up spindle controller to K1 Relay

« on: October 12, 2015, 07:55:11 AM »

Hi all,

I have a PMDX-126 and ESS.  I have all the drives working but struggling to understand how I connect the spindle controller (Lenze 534), to the K1 relay.  Is there anyone that can point a newbie in the right direction?

I have (hopefully), attached a photo showing the spindle control board.

Regards

Parallel Port breakout boards, motherboards, and dedicated accessories / PMDX-126 + SS packaging for two machines

« on: August 20, 2015, 07:15:51 AM »

Hi all,

I have an ESS, currently I have it within a plastic box with a PP cable to my machine and the BoB within the machine.  But I am looking to upgrade my BoB (to PMDX-126).  If I plug the PMDX-126 straight into my SS then I maybe best mounting the SS and BoB within the machine housing.  Making both boards dedicated to the one machine.  Do I have an option to add the PMDX-126 to the same box as my SS with a PP cable running to the machine or will this limit the number of I/O etc?  My issue is I have a 2nd machine which I would also like to get up and running using the same system.  I dont really want to buy two SS's if I dont need to.

Any thoughts welcome on how others get round such problems.

Regards

Steve
