VB and the development of wizards / M6 and Spindle Stop - How not to stop spindle with M6?

« on: November 12, 2023, 09:05:12 AM »

I have a machine with 4 spindles. For the tool offsets I'm using M52 commands im M6 macro.
All four spindles are driven with the same frequency inverter
All is working fine 
I'm using M6 Tx command to automatically set correct M52 offset in my G-code.
The only problem is that M6 automatically shut down spindle when it is executed.
This I do not need since I do not change the tool "phisically" in any spindle)
At the end  of my M6 macro (G52 offset) I need to turn spindle again On (or in my G-code after M6 command)
That makes delays in my work 

Is there any option to set Mach3 not to shut down spindle when calling M6?
(Also the completely empty M6 macro shut down the spindle)

Thanks

VB and the development of wizards / While IsMoving issue - Procedure - the loop freezes

« on: October 24, 2023, 08:25:11 AM »

Greetings,
I have a very unusual problem that I have never encountered before.
Basically, it is a very simple procedure that does not work on the machine where I have installed the latest version of MACH3 (Mach3Version3.043.066) and WIN11.
Mach3 is combined with CSMIO-IP-S
In any procedure where While IsMoving() is used, the loop spins endlessly even though the previous command - the G-code for moving an individual axis is finished (The axis is successfully moved to the required position)

Example:

Code: [Select]

Code("G01 G53 Z0 F200")
While IsMoving
Sleep(20)
Wend
Even without Sleep(20) it doesn't work
I tried reinstalling MACH3, also running it in compatibility mode with WIN7, XP,... without success

On another computer, the same procedure works without a problem.
I've tried many things but unfortunately I can't solve the problem.
Any other suggestions on how to solve the problem - without replacing the computer? (this one is new)

Thanks

General Mach Discussion / Circle not circle but oval - no backlash on the axis, steps per unit set OK,...

« on: November 08, 2020, 06:26:30 AM »

I have read a lot of posts about circle cutting - no circle but oval, and checked and tried many suggestions but no success.

My machine still doesn’t cut correct circle.

1.  X and Y backlash les than 0,03mm
2.  Steps per unit equal to both axis - the same ratio between AC servo motor and ball screw
3. Following error on both axis during circle cutting near 0 - there are 750W AC servos on light machine - over dimensioned motors.
4. Acceleration/deceleration equal to both axis.
5. When cutting square 100 x 100 mm, both dimensions are in +/- 0,02mm
6. Circle dimension in X and Y axis is also 100mm +/-0,02mm (when cutting circle 100mm)
7. The difference in diameter measured in 45° and - 45° is 0,6mm
8. By cutting circle in CCW or CW direction, diameter difference in 45°and -45° remain the same but vice-versa.
9 Cutting speed doesn’t change result - cutting 150mm/min or 1500 mm/min. gives the same result.
10. I'm using LPT BB

I have no idea what else I can do to solve this issue.
Any suggestion appreciated…

VB and the development of wizards / Wizard "Save as..." and "Load"

« on: August 03, 2015, 10:04:31 AM »

Hi

Is there a possibility to store the data entered in a wizard under different names in order to  be loaded  back later  and taken a small correction
(not only last entered data)?
I know that the G-code can be saved under different names, but if  later I want to change something I have to write  back all  the parameters in the wizard and generate G-code again.
G-code is probably not possible to convert back into wizard DROs...?

Example:

Load wizard - Circular Pocket

Enter all necessary data...
Save entered data As....
Generate G-code
....
....
....

Load some saved data into Wizard (not only last one)
Make  corrections...


Hope I was clear enough to get some advice...

General Mach Discussion / G0 Feedrate is not on maximum

« on: June 16, 2015, 12:34:46 PM »

Hello

I have one strange problem with G0 feedrate.
Maximum speed displacements in "Motor Tuning" is set to 8000 mm / min. and it is actually that when moving machine with the arrow keys.
Even when I write to the MDI, for example:
G01 X200 F6000
the moving is correct  - fast.

However, if I write:
 G0 X200,
the moving is reduced to 1000mm/min. (also in the window "feedrate")
Also from G-code  G0 is slow, just 1000 mm / min.

I checked all the possible settings ....... please if anyone can help me before I go crazy.


Thanks

General Mach Discussion / Lot of problems with Mach3 and CSMIO/IP-A

« on: October 24, 2014, 02:46:32 PM »

I think I will go crazy ...

I made a special cnc milling machine for the client. I used CSMIO / IP-A, PoKeys for external keyboard and licensed Mach3.
I thought this will be a reliable...but  

Time and again, there are new problems ...

G31 does not work with CSMIO and last version of MACH3  
With an older version of MACH3 does not work PoKeys!
Mach3 is often "lost" all the settings if I go under "Ports and Pins"  

Current problem:
Spindle automatically turns off randomly during the program.
I tried to increase the debounce interval....... without success

The customer is upset and wants to return the machine.

Is it possible to eliminate this problems or MACH3, PoKeys and CSMIO are not sufficiently reliable?

Thanx to all!

Machscreen Screen Designer / Where is the main screen???

« on: September 21, 2014, 11:31:29 AM »

A few days ago I noticed that on startup, MachScreen  display only the Properties window.
The main screen is visible only  a piece of second and then disappears.
I tried on the other two computers and everywhere is the same.
I've tried re-installing MachScreen, but nothing  ...
What happened?
Is there any way to solve this problem?

Thanx!

General Mach Discussion / Mach3 2 x 3 2 x 3 axis, driven in the same time. Is that even possible?

« on: July 07, 2014, 08:29:22 AM »

Hi to all

I'm planning to build a machine with two milling spindles, each mounted on its own coordinate system (X, Y, Z   ;  A, B, C).
With such a structure of the machine,  I want  to process at the same time, two different contour on one workpiece.
Of course, the G-code for each contour need to be  independent, but both should be implemented  at the same time.
Is such a thing possible?

Thanks to all!

General Mach Discussion / Faster output

« on: March 20, 2013, 05:27:31 PM »

Hi
I have made laser, which is controlled by Mach3. To turn laser on and off I used the spindle output and function of M3 and M5.
Laser power is controlled by PWM output.
This all works well and good.

The problem only occurs at the end of cutting or engraving because laser does not go off fast enough.
The function M3 takes too long to turn off laser.
I put to 0 all delays for spindle on and off , and is still not fast enough.

Is there any alternative to turn on and off laser faster?

I have to say that I am using ESS and the transistor to turn on and off the laser - no relay!

Thanks for the suggestions!

General Mach Discussion / Rapid feedrate (shift button) and jog feedrate (analog)

« on: August 20, 2011, 08:16:32 AM »

Hello

I know that in MACH3 is  possible to move an axis in rapid feedrate using key SHIFT + arrow (Hotkey)
In this case it is necessary to press SHIFT first and then an Arrow key.
Is there any possibility to enable or disable rapid (G00) speed in opposite way (first ARROW and then SHIFT)
In this case it is not necessary to release an Arrow key for change the feedrate from JOG to RAPID or vice verse.

I want also to change JOG feedrate with analog input - when Jogging
Is this possible?
