General Mach Discussion / Machturn

« on: August 07, 2009, 03:29:22 PM »

I have a pipe 25mm in diameter with an 8mm diameter hole. I want to bore (or internally turn as VisualTurn puts it) the interior to 12.5mm in diameter. In other words I want to enlarge the hole 4.5 mm in diameter. I created the stock and final workpiece dimensions in VisualTurn and created the gcode then postprocessed the gcode through their Mach3 postprocessor. When I go into MachTurn the code is giving me external turning and is in inch mode. What can I do?

Please ignore the speed and feeds. I can always adjust those later. My problem seems to be that I can't get Machturn in mm mode and it doesn't understand the stock that I am using.

General Mach Discussion / Re: Motor tuning on machturn

None of that should matter should it? I am using a pendant to move the lathe 1" and then adjusting the software "steps per" to match. My problem is that changes to "steps per" are not making any difference in the outcome. For instance the last adjustment, when 1" movement showed as being 10" on the DRO I then needed to divide the steps per by 10. That brought the steps per to 100. After making the change to steps per, I run the same test and the DRO still said 10"

I can't get my motors tuned in Machturn. I go to my lathe, move x and z 1 inch then go to machturn and adjust my steps per. I'm down to 100 pulses per and mach still says I am moving 200 inches. What the !! I am in inches as far as I know. Any help?

I guess I can build a longer signal triggered by the real one. I don't see how that is going to help synchronize with the spindle speed though. If I increase the signal length that will limit my speed to whatever length I increase it to / what ever rpm the spindle is moving.

Yes, I am using the pmdx 132.

I went into ports and pins and tried every combination of high, low, port on pin 11, my encoder input pin and machturn will not see it. It shows up on the scope at all speeds. Calculated correctly at 1 rpm. I used the automatic setup of input but still no luck.
Any ideas?

General Mach Discussion / How do you install index pulse from lathe to PMDX-132 Breakout

« on: July 09, 2009, 12:19:36 PM »

  Assuming I have a working pulse coming from my lathe, how do I hook it up to a PMDX-132 breakout and have Mach recognize it in MachTurn?

Found it.
NO POWER IS BEING SUPPLIED TO THE MPG (AS YOU THOUGHT). I thought that it would be supplied by the 5V ttl from the SS board.

Thank you.

Yes, I have the SS "Port1" connected to a V1.8 SoundLogic breakout board.
