dspMC/IP Motion Controller / Re: DSPMC Macro
« on: December 13, 2013, 06:36:37 PM »
Thanks John. That's a great write-up. I have a unique situation with the glass scales. Instead of moving the table to a limit switch, with these scales, I only have to move 1cm to find the tables absolute position. The position on the scale is encoded into the z encoder. I want to take advantage of this. I don't want to have to install limit switches.

My question is specific to the DSPMC. The macros are coded in visual basic. I expect that runs pretty slow and may not be able to keep up with the encoder pulses. I also need to know how to read the  Z input on the DSPMC. I didn't see a way to do this in the Macro user manual. I was hoping Rufi would have some answers.

dspMC/IP Motion Controller / DSPMC Macro
« on: December 12, 2013, 09:47:54 PM »
I have Acurite glass linear scales for a mill. They provide the position feedback and go to the encoder inputs of the DSPMC. The encoders have reference marks that are connected to the Z input of the DSPMC. The reference marks are about 1cm apart. The are positioned slightly different between marks so that after moving between marks, the count of the encoder will indicate the exact position of the table. I want to be able to count the encoder pulses between reference marks to get this exact positioning.

1. Will the macro be fast enough to do this?
2. I've read the macro manual. I don't see a way to detect the reference (Z) input. How can it be detected and then run a count until the next mark?

dspMC/IP Motion Controller / Stepping Moves Both Axis and Wrong Amount
« on: November 02, 2013, 05:38:05 PM »

I posted this in the General Discussion. Hood reviewed my .xml and thinks this problem may be related to the DSPMC.

Pressing the Tab key to get the pendant, I set the step function to .001". I set the Jog mode to Step. I hit any of  the left/right/up/down arrows on the keyboard. In all cases, when just pressing one arrow key, my mill moves -.005" on the X axis and -.02" in the Y axis. It doesn't matter what arrow I press, I get the same results. Both axis move in the same direction, the same amount.

But when setting the jog mode in the continuous mode, the arrows behave correctly.

Using a USB pendant, the same thing happens.

What am I doing wrong?

Thanks.

Thank you for the quick response.

I disabled the plug in, disconnected the pendant, restarted Mach3, disabled the plugin again. Same results.

I'm not sure what .xml you want. I have attached Mach3Mill.xml

I don't know what I did wrong the first time. But deleting the file and reloading it did the trick.

Thank you,

dspMC/IP Motion Controller / Upgrading Issue
« on: October 12, 2013, 01:51:41 PM »

I moved my Mach 3/DSPMC to a new PC. When doing so, I upgraded the software/firmare. I've moved the 3.5.9 plugin to the Mach 3 folder. I've updated the firmware to 7.14.

When I open Mach 3, the status reads 'DSPMC/IP POnline. Plugin 3.19, DSPMC: 7762/0719, CPU Rev: 6'

I also get the error 'Encoder Polarity or Encoder Debounce out of range...'.

The Status line plugin does not match what I put in the folder. What am I doing wrong and how do I get rid of the error?

General Mach Discussion / Re: Output Behavior

Yes. It was a stupid mistake. The outputs don't behave unless the reset button on the Mach3 screen is RESET.

Ok, thanks. I will look further into this.
