General Mach Discussion / Re: Alternate modes of homing

Thanks, I will give it a try. These drives basically have a PLC built in so I can just program to watch for a home signal to run that routine.

Pretty neat little motors, 10nm resolution.

How do I set this up?

General Mach Discussion / Alternate modes of homing

« on: June 15, 2016, 03:42:32 PM »

I am putting together a system using a couple linear motor slides with Parker ViX-250IH servo drives. The drives have an internal homing routine that handles everything. I can trigger it from an input or let it home itself at startup.

Can I make Mach just send a signal out to start the homing routine and then watch for the home good signal from the drives?

General Mach Discussion / Reinstall and modbus settings not sticking

« on: February 28, 2015, 10:05:06 PM »

I had a hard drive crash the other day and had to rebuild the pc, I still had the mach3 folder archived from last year so I did not loose and setting file. Everything went back together smoothly almost....

My problem is the Homann Designs MP-01 units. It uses modbus to talk to mach3. As soon as I boot and hit reset it says I need to configure the pendant which it has been already. I then go to the Serial Modbus dialog and everything is reset, Port is 0, Speed is 0, Parity is reset to 8-O-1, and timeout is blank. If I set these to where they are supposed to be 1, 115200, 8N1, 100ms, and click run and apply I start seeing the leds flash on the MPG's breakout like it is supposed to. I hit the reset button again and still get the "pendant needs to be configured", so I go to the plugin config, delete the pendant (says there are two instances), and create a new one. Now the pendant works.

If I quit mach I have to do this all over again, everything gets reset. Other settings like parallel port addresses stick.

Running Win 7 Pro 32bit with the latest Mach .066, same as before the crash.

I used Mitsubishi's MR-J2s on my Hercus lathe. You can drive them with current limited 5v straight from the bob. You dont need to use 24v logic. Now I did have to on my mill which I used MR-H drives.

Found the spindle issue too. Mach does funny things when the spindle speed is called again while the spindle is running.

Didn't think about that A axis. And you were right too. Thanks Hood!

Still the issue with the spindle slow down. But i am ok since closed loop is working.

Heres the file. I need to figure out how to switch back from Machstdmill. It does not like it when I try it the old fashioned way.

Here's the fixtures file. I changed the extension to .doc so I could upload it.

General Mach Discussion / Strang behavior. Slow travel to/from G54 location

« on: May 30, 2011, 03:32:46 AM »

OK, I have something weird going on and I cant figure it out. I have three programs for some parts I am making. All of them use fixture locations (multiple vises on a fixture plate) using G54 to G57. First one, winder base runs fine. Second and third programs winder plate, and winder side act funny. When traveling to and from the G54 offset it goes real slow. Like 13ipm, when it should be rapid. The thing is I cant find anything in the code that should be doing this. Once it gets to G55 it moves fine and rapids as it should to the next location in G56 and G57. When the program finishes and it is at G57 and I hit start it does it again. Very slow move to the location in G54.

Another weird thing happening in these two programs is when it is traveling in between fixture offset location the spindle speed dips. In closed loop spindle it will recover to its speced speed but in open loop it just drops a few hundred RPM.

I am including all the files and my XML. Help!

I am running the lockdown version of Mach. Spindle feedback seems to be broken in the latest dev version for me. Also using machstdmill.

PoKeys / Re: Pokeys boken with 10.6.3

« on: February 12, 2011, 07:43:16 PM »

OK, got a chance to mess with it again. I moved mach to an archive directory and reinstalled the latest mach and the pokeys plugin. In copied my xml for the lathe and the macros and brains it needs to work.

It still does the exact same thing.

Now, one thing of possible interest is I chose not to install the parallel port driver when I reinstalled mach. I thought the driver was at a system level and didnt need to be reinstalled.  At that point the pokey seemed to respond as it should. As soon as I installed the driver the pokeys got laggy again.

Is there somewhere I can download older versions of the pokeys plugin so I can at least figure out when thinks went wonky?
