CS-Lab / Re: Looking for feedback on running a CSMIO/IP-A with Mach 4

« on: February 01, 2016, 03:59:22 PM »

Hi Dan,

I am doing the same thing with Hurco MD1 , be sure to check how many outputs you will need, 16 on IP/a might not be enough so check and order expansion IO module if needed, inputs number is just enough.

Also on mine all axis limit switches and 8421 counting the tool number are 5V proxy so can not be directly interfacesd to CSMIO as all IO works on 24VDC

Do you happen to have a wiring manual with yours? I got stuck in some wires hehe

You should try another PC, this one seems to have bad latency issue or use some motion controller for generating pulses if you need more than 25khz for step lines.

I think that for the cheap route you should have gone with cncdrive dc servo drives DG4S-16035 and unwound the transfomer get acceptable voltage for them (160V)
this way it may be somewhat better, but it will take you more time to figure all out and if one drive goes bad how will you find the replacement.

Only inputs that look like +/-10V input to the drives are pins 1 & 2 on each axis X11 X21 X31 (but they have a + and - printed on the acrylic so I may be wrong) , fire up the old control and check with the multimeter what it shows?
If the drives are all plugged in to some kind of motherboard then you should look there, cant see really from the pictures.

p.s. I just finished one Biesse with IP/A and its really easy to wire it and set it up if you have original schematics

PoKeys / Re: Pokeys57CNC Step / Dir Spindle and Spindle misused as 4th axis for toolchange

« on: January 21, 2016, 10:57:02 AM »

I think you can set same pins for A axis and spindle, then use M3 and S commands for regular work and in toochange macro be sure to stop the spindle and use A axis.

If its VMC200 Emco then I may be of some help as I service one of those. If that is the case you will need 3 operations for the spindle

1. regular spindle ... rpm direction etc

2. index to home position set by the encoder behind the spindle case, to properly engage SK40 and leave them in toolchanger
also if the position is not correct the gear on top of the spindle will not engage properly with one on the toolchanger and will strip its teeth (plastic if its ruined order one from Emco they got replacements)

3. spin and count the proxy switch to change tools while in most upward position detected with one of the limit switches behind the z axis

toolchanger has one proxy more to detect tool No1 so its practical to have a macro for finding that one too.

General Mach Discussion / Re: THC up/down dont moving Z axis

« on: January 22, 2015, 05:34:51 PM »

Had the same problem... CSMIO IP-S not responding to THC UP / DOWN

Solution is to not use the standard M3 that starts the spindle relay DoSpinCW() but use ActivateSignal(OUTPUT1) and everything works as expected.
Don't ask how we got to this solution... lucky for us we used two separate heads for plasma and oxy and separate Mach3 profiles and the oxy profile did not use
spindle relays and its capacitive thc worked.... that gave us a clue... after couple of DAYS

Using the option that enables thc even when not in thc mode should not be used.

Mach SDK plugin questions and answers. / Re: Plugin or Script to Modify Gcode

« on: May 30, 2013, 11:07:02 AM »

Theminor , how did you alter the second Z axis zeroing routine. It won't work for me if I probe and try GetVar(2004) which is my B axis or second Z. Its said that probing won't work if a rotational axis is moving (abc) or there is no movement in XYZ axis

I am currently using a trick doing a swapaxis with Z and writing the value back to B axis DRO in the end

Real nice work Peter.

One question, can you show us how you assembled gantry sides?

PoKeys / Re: Pokey55 and MPG issues

« on: February 20, 2011, 05:36:45 PM »

I am experiencing some issues using pokeys with mach 3.043.010, my pokeys has updated to latest firmware 2.1.18, sn 11983
using mach plugin version 10.6.4.

All features work so is the MPG when looking at the pokeys config software it has great response, I got FRO and SRO pots working with mach brain.
MPG also works but when looking at the number of ticks its not updated regulary, even when turning it slow it jumps trough values by increments
of 1 to 10 sometimes. Pokeys read raw encoder data updates values regulary.
Even stranger thing happens with mach and pokeys config read raw encoder data window is open, mach-s MPG value jumps from 0 to the steady value, in radnom short intervals, and comes back to true value indicated by pokeys .

My guess is that the pokeys and mpg are working correctly, and it must be something in the plugin or mach, I have disabled all other plugins and brains but the
problem remains.

Any help would be appreciated.

Here is the screenshot of the reseting mpg value:
