So, I have had mach 3 running a stepper converted hardinge CHNC lathe. Mach has (until today) been only controlling Z and X axis movement.

Today I finally got my collet closer running with a solenoid and a relay board through mach. additionally, I now have a VFD running the spindle through mach using my BOB's 0-10Vdc output. the only other thing I changed was to set up a mechanical estop.

These three new additions work very well, and relaibly. so far.

when I tried to run a working piece of code (created in Bobcad ver 23) I was stunned to find that my G00 moves were now so rapid that the G203V's I run were faulting out.

My motor tuning settings are the same as they always were, but now my G00 is super fast.

If I change my steps per for the Z axis from 40000 (the original always has worked correctly number) to 10000, the G00 moves are still very rapid, but are slow enough to not fault the G203v.

this has led me to believe that somehow, my settings for the max motor speed allowed are all messed up. I dont get it, I thought that the max motor speed (rapid) was a function of the motor settings tab. How can Mach be overriding this?

I tried switching a spare G203V into the system, but the G00 being wildly fast still happened.

I am attaqching 2 xml's one from 10 18 2011 which worked just fine when I saved it, and the other from today that allows me to use the CC, VFD spindle and EStop switch.

I hope you guys can help!

The part we kept getting stuck on was the autopolling input and output start registers. Nothing anywhere we could find seemed to tell us where we could find what the start registers should be. We looked in Cubloc book, online, and finally when hood pointed out that Henrik had used both serial and the plugin, we then had a known good number to start with for the start register.

Finally last night (late)we had mach communicating with the cubloc/cubase32/relay board. We could MDI T0101 etc, and trigger a different relay for each seperate T*********X. A great sigh of relief was heard coming from the three of us. We had been struggeling for many hours to get that elusive piece of info that was- a working start register number!

We have lots of work to go, but now that we have at least got T*********X triggering relays, we feel the worst is over, we hope...

Fdos- I am building an encoder simmilar to the original Hardinge encoder, made of hall effect sensors. I am using all eight sensors as inputs to the cubloc, so no need to decode anything.

Next are these tasks-
connecting relays on the cubloc to the solenoids.
getting the encoder installed.
getting cubloc to write the encoder position to Mach.
writing the Cubloc tool change code.
Installing the turret up or down sensor.


A big thanks to everyone for all of your help.

I promise to add everything that will be helpful/needed for the next person trying this. I am determined to not have the next guy struggle this much...

Fdos-

Thanks for chiming in.

"The Cubloc runs a basic loop which looks to see if a new station has been requested and operates the air valves to achieve this." very good explanation!

Fortunately, the CHNC turret actually only runs one direction.

I have contacted the guy (Vince here) who made that video many times. sadly he is too busy to help, and cant provide me with any code or settings due to the PC that runs his lathe being down.

Its a heart breaker, knowing that data is all there, just inaccessible...

Hood-

Thanks. you were right about the plugin and how Henrik set his up. it is Serial via the Plugin. I just did not see that..

My understanding (very incorrect) was that to use the plugin, I had to comm over tcp.

Peter-

Thanks. I get the bit about the M6macro. your and Hood's help is invaluable. Additionaly Peter, I look forward to spending money on your products whenever possible. I wont forget that you were willing to help...

Sure, I get it now. Can you share your M6start?

Peter-

Thank you SO much. I am going to try to piece together what you have written in my mind. Every bit is bringing me a bit closer!

Would you be able to post your m999 start macro? if you did not want to post it, could you email it to me? natefoerg@gmail.com

Looking at it would help me fill in the blanks...

Interesting...

He is using the plugin and serial setup. He mentions brains, but I dont see him using one.

I am using Version R3.042.040 was the "Plugin" added in later versions? I dont have it...

keithmech-

Yes, I have studied it many times. Sadly, it pertains to TCP and not Serial...

Interesting Hood. sure it was your settings. long day...

What does the "oct" stand for? something to do with 8 bits?

Can you explain how the Start Addresses are used? in plain english?
