General Mach Discussion / Re: Is there a way to Independently move an axis while moving others?

« on: July 14, 2011, 09:51:29 AM »

WHen the X slows the A HAS to slow as well to maintain a coordinated feed (;-) You cannot have one axis running independant of the other. Besides IF it did your screw would not be accurate at all.

The angle change at the ends will NOT be 180 deg (;-) think about it.

The axis will maintain a proper "cut" if it is coded correctly

You must have really SLOW accelleration on the axis's.

Are you running radius comp on the A axis?

Attached is an example of comping the ends for a smoother transition to return. Note that IF you are looking for a true constant velocity of the screw feed then this is not the way(;-) as the linear feed of the screw will slow as it reaches the ends

VB and the development of wizards / Sus WhileDO()

« on: July 13, 2011, 10:55:35 PM »

Has anyone figured out a way to Suspend a macro so you can do a Jog move in mach then press a KEY to return to the macro ??

I think it is time to ask for a

Sus WhileDo()
Susend

How about it Mathew???

Mach does NOT have that function as a normal feature.

Depending on what Z home method you use the G68 MAY or MAY NOT work.

With the G28.1 style Z home(TOM) it will NOT work

With the G31 style Zhome(TOM) it WILL work

Are you running CV? With CV on there will be no lag the moves will all blend in to a smooth continous motion.

Just a thought, (;-) TP

IAN, What about IF we try to send the data stream out throught the Serial port using the serial modbus ?

I know Mach does not have a problem with that.

Also Henrik has developed a proper serial port useage with mach through an outside DLL. It allows you OPEN the port and then send recieve, then close the port when done.

I don't have the LCD display here so I can't help develope any solutions in real time. (;-(

Just some thoughts, (;-)TP

One thing that I have learned with Mach and macros is AFTER every ACTION statement place a While Ismoving(), wend. This HELPS force mach to stay in thread snyc. It is NOT just for movement(;-) I use it as a thread placeholder.

Just a thought(;-) TP

General Mach Discussion / Re: Mach 3 is hanging while loading file

« on: July 13, 2011, 01:28:37 AM »

NO problem loading here it took less than a second. Loaded it about 20 times all the same.

You may want to look at your Hard Drive AND your Memory chips. One of them may be heading south.

No on the seperate moves. BUT your code runs FINE here. IF you want a symetrical screw then you need to comp the ends a little to make a smoother transition to the opposite direction. I do something similar to build a level winder for winches.

Are you running backlash comp? That is the only reason I can think of for the "Wait".  With backlash comp ON the machine has to Cycle out the backlash BEFORE it changes direction.

Just a thought, (;-) TP
