dspMC/IP Motion Controller / Re: Voltage Output on M3
« on: January 06, 2011, 03:08:38 PM »
Hi,

As for now that is how the the system works, as soon as you set a spindle speed in mach3 the motion controller will put out the commanded analog voltage.

This is something I want to change in the future but it works fine for VFD's so I haven't pushed to get it changed!  Just a side note there isn't any acceleration or deceleration on the analog.  It is always on according to the set spindle speed.

dspMC/IP Motion Controller / Re: dspMC and Pokeys

Hi,

You will want to connect the MPG to a hard encoder input or a soft encoder input!  Don't try to run the mpg through the pokeys!  As far as FRO and axis selectors you should be fine using the pokeys.

Hi,

I am trying to find a way to see if an axis is currently slaved.  Is there any VB or C++ command that I use this to read this?  I already have a custom plugin so it would not be a problem to add this in.

Thanks,
Andrew

Hi All,

I have been watching this form for a while and the work you are all doing look great!  I was curious if you had plans to make LazyTurn create gcode for ID parts instead of only OD parts?

Thanks,
Andrew

Thanks for all of your help!

Just to let everyone know version 3.042.029, 3.042.034, 3.042.035, 3.042.036 do not thread right at all!  Brian sent me a new driver to test and it fixed the threading... They will add it in the next release.

Also if you are using G95 you might want to put this code in your M3 macro to make sure the spindle is up to speed before the motion starts.

DoSpinCW()
While ((Abs(GetOEMDRO(39) - GetOEMDRO(202))) > 20) 'Wait for spindle to get up to speed!
Sleep 50
Wend

 If the spindle is not at commanded speed right when the motion starts mach will not cut the rest of the program at the commanded feedrate even after the spindle is up to full speed.

Hood,

I will test that... But I would think that if I told it to move a few inches at a slow speed after a few seconds I know the spindle would be up to full speed so shouldn't mach3 have sped up the motion to match the spindle speed?

Hood,

I think I have my spin up time set to the default 1 second... But I tried slowing the feed down to F0.003 and move 5 inches and it ran at 0.0007 so it would have had plenty of time to spin up to the full speed. It took about 5 min to make the pass and the feed was wrong the whole way!

Thanks for the reply,

No, I am not using the timing input and I haven't ever used it.  I have been playing around with a few different versions and can't seem to find one that will run this program and display the feedrate correctly every time.

G20
G95
G97 S1400
M3
G0 X0 Z0
G1 Z5 F0.1
G1 X5
G1 X0 Z0

M30

The first time I start up mach3 and run this program it looks like it is working right. The feed dro reads 0.09 to .1, but the second time I run it the motion is very slow and the feed dro reads around 0.045.

I have version R3.042.020 threading fine but I can't seam to get passed this feed problem.  I just tested version R3.042.030 and still have the feed problem... I haven't tried threading on this version yet.  I did find that installing mach3 over top of another version sometimes messed a lot of things up so this is how I have been installing every version I try:

Backup XML, licence, screen set and macros.
Goto Device Manager and uninstall the Mach3 Pulsing Engine.
Goto Ad and Remove programs and uninstall mach3.
Delete the Mach3 Folder.

Reinstalling....

Install the new version.
Copy backed up files into the mach3 directory.
Restart Computer.

If anyone has seen this problem please let me know!

Thanks,
Andrew

Note: I know my spindle feedback is working right because I can thread fine with version R3.042.020...

Hi Everyone,

Has anyone successfully threaded with version Mach3 R3.042.036?  I have not gotten it to thread correctly.  I have version R3.042.020 threading well but the current feed rate DRO is not even close to reading the right values.

Thanks,
Andrew
