General Mach Discussion / Tangential Problems
« on: May 21, 2013, 11:32:09 AM »
We've been using Mach for a number of years and a lot of our systems use the tangetial mode. One system is a high speed waterjet cutter that uses tangetial mode to cut rubber with a beveled edge.

There is a problem that has crept into the later versions that screws up tangential mode. When I cut a circle all is fine. The propblem is in parts with radiused corners. When the motion tansitions from a straight edge to the 1st radius Mach will take a nosedive in speed (about 90% drop) and the head is rotating a lot more than it should to follow the radius. Anyone else seeeing this? As mentioned, we've used tangetial for years without this problem. BTW, we do use the ESS SmoothSteper board.

Thanks! This did the trick. Didn't think about using "Not GETUSERLED".

General Mach Discussion / Help with button code
« on: June 04, 2012, 09:16:39 AM »
The task is to get either or a combination of the vertical axis servo motors (X,Z,B) to run, based on the condition of the LED associated with each axis.
If the X axis LED is on then the X axis runs; if both X axis and Z axis LED's are on then both will run, etc.
I would like all motors to run simultaneously - vs sequentially, if the LED status indicates more than one motor is to run.
BTW, the Y axis indexes a belt between the vertical axis cycles.
Right now, the current button has the motors running sequentially.

Thanks in advance for any help.

This is the code I currently have on the button.

MoveBelt = GetUserDRO (1060) 'Belt Index Increment
code "G91"
code "F5"
If GETUSERLED (1031) Then 'checks X axis LED
code "G1X-1"
code "G1X1"
End If
If GETUSERLED (1032) Then 'checks Z axis LED
code "G1Z-1"
code "G1Z1"
End If
If GETUSERLED (1033) Then 'checks B axis LED
code "G1B-1"
code "G1B1"
End If
code "F200"
code "G1A" & MoveBelt
While IsMoving
SETUSERLED (1036,1) 'turn on A axis LED
Wend
SETUSERLED (1036,0) 'turn off A axis LED
code "G90"

Galil / Re: Gantry homing problem
« on: January 20, 2011, 12:33:33 PM »
Just found out that someone here has already emailed you directly on this matter (I didn't know this and he has been out of the office).
I believe he has already sent the GalilDebug.txt file to you.
The "Home slave with master" is indeed NOT checked.

Make sure that the "Home slave with master" is not checked in the Mach General Config.

The Galil plugin puts the master/slave axis in gantry mode.  But if Mach sends movement commands to the slave axis, then the movement of the slave axis is doubled!

In the next release, I will handle this case in the code so that no matter how the General Config is setup, it will do the right thing.

But...  as Kenny said, a GalilDebug.txt file would be nice to verify this.

Galil / Gantry homing problem
« on: January 19, 2011, 02:24:53 PM »
Did an upgrade on a 4'x8' gantry style waterjet system using a Galil board (DMC 2143).
Using existing motors and analog servo drives (Advanced Motion Controls model 25A8).
Motion is spot on (jogs, runs parts, etc.) but with one problem ... when we try to home the machine, the right motor on the gantry moves faster (about 2X) than the left motor on the gantry.
Any ideas?

LazyCam (Beta) / Re: Problem posting Lazycam to Mach

I'll try to get a file.
Yep, everything was gravy till he broke his computer and had to replace it.
Old and new computer are both XP machines.

Thanks for your help!

By "load a job" I mean load and run a previously posted job.
Job is created from a software pkg. such as Lazycam.
Job is then loaded from within Mach.
Customer is unable to load any previously posted jobs.

More news from the customer.  When he tries to load a job from Mach, nothing happens; job is not loading.  He is not real computer literate but AFAIK, he has installed Mach properly and copied over his old setup files and macros.

I've seen this before as well but can't remember the solution.  Using the latest versions, downloaded on Friday. AFAIK, he installed both at the same time, then copied over his screen sets, etc.   His older version (on dead computer) worked as expected.

LazyCam (Beta) / Problem posting Lazycam to Mach
« on: January 25, 2010, 10:46:48 AM »
Due to hardware problems, a customer had to re-install all his software to a new computer.  Everything is up and running, but with one small problem.  When he posts a file out of Lazycam and returns to the Mach screen, the new Lazycam job is not on his Mach screen.  All the option settings in Lazycam seem to be set correctly.
