Mach Screens / Softlimits on RnR card---, min-max input value
« on: February 13, 2021, 03:06:40 PM »
I use a USB motion controller for Mach 3. These do not support use of softlimits unfortunately.
I input all my positions manually on the DRO on a custom screenset.
BUT I would like to know if anyone has any experience on solving the issue with the missing softlimits?
Is there a way of setting a max-min value for each DRO input value, and have a pop-up msg if a value is entered outside this range, by use of a basic script?

Best regards

Brains Development / Comparing DRO´s in a Brain
« on: January 14, 2020, 05:55:52 AM »
In a custom screenset I am using a compare function of an OEM DRO and an axis DRO to set a OEM LED to green if the axis has moved to the correct position (same as the OEM DRo). This is working in most cases, BUT; Sometimes the positioning is just a little off maybe 1/1000 mm. This does not matter , but as this is not an excact equal value in the compare, the led does not turn green. I have good resolution in the motor tuning with approg 600 steps/mm (no deciaml after comma) , so I am not sure why it sometimes calculates off.

My question is; Are there any way of writing a formula in a brain that says something like this;  (A = B +/-0.250) ( I know this is not mathematically correct, but hopefully gets the explanation up front)

In PLC programming it is possible to write a compare block like this: Variable1 < Variable2 + 0.025  AND Variable1 > Variable2 - 0.025 -----> Output

Or, could Mach3 be set up to use lesser digits? ( I think I have read somwhere that there are actually lots more digits in the code of the program, but not more than 4 after comma is shown in the DRO.

Any good suggestion on how to solve this issue is greately appreciated

VB and the development of wizards / Anyone building wizards for others?
« on: March 22, 2019, 05:56:40 PM »
Hi
I am quite familiar with designing screensets, and have just started looking into VB scripting and brains.
Brains is not the biggest problems as I code and debug PLC´s on my dayjob, but the VB scripting is not down my alley ....yet.
Anyway, to make confusion even bigger I started looking into making a wizard for this custom screenset I just made.

I can design the page with the basic layout of the wizard, and explain the function I need.

So my question is: Do any of you people with this knowledge do this kind of work for a reasonable price?

General Mach Discussion / Auto Calculator Size
« on: March 17, 2019, 10:14:09 AM »
Hi I am working on a new custom screenset, and I will be working on a touch screen.
So for this I am going to use the Auto Calulator feature for the input of the DRO´s
I have searched this forum and found someone ask the same question a few years back, but no response, that I can find.
My chubby fingers are a little to large for the small keys on the Auto calculator.
The function is great as the keypad pops up when you press the desired DRO, but again I would like it to be a bit larger.

I know that there are no further development on mach3 anymore, but If anyone has been able to solve this issue, or have some other good solutions, it is greatly appreciated

A numeric keyboard with an enter key is all that is needed

Machscreen Screen Designer / Change background color of DRO when not in position
« on: March 13, 2019, 05:52:14 PM »
I am creating a motion control system based on a mach3 shell. BUT I would really like a feature that I cannot figure out.
I am not very experienced on Klaus´s Mach screendesigner, but I have made some custom screensets before (for other motion control applications)
I am using a custom DRO input field to move a servo into the position entered in the DRO field.

The way I solved this is by using a user defined OEM code for the DRO, and after entering the value I run a script on a button that looks like this:

Xtcp= GetUserDro (1200)
Ytcp= GetUserDro (1201)
Ztcp= GetUserDro (1202)
Feed= GetDRO(18)

Code"G0"
Code"G53 Z"&Ztcp
While IsMoving
Wend
Code"G53 Y"&Ytcp
While IsMoving
Wend
Code"G53 x"&Xtcp
While IsMoving
Wend

Setdro(18,Feed)

Now back to my problem: I do not want to mess up the screenset with a DRO showing actual position.
So after entering the value I would like the background of the input DRO to be red as long as the target value and set value are not equal.
Optionally, custom OEM LED show that the machine is moving, and then switching to green when in position.

Is there anyone out there that could help me along with this, or tell me if I am asking to much of the software?

Best regards

General Mach Discussion / MDI not working
« on: February 24, 2017, 06:43:22 PM »
I have searched the forum, and not found any info that helps me, this is the closest I got http://www.machsupport.com/forum/index.php/topic,29050.0.html
MDI does not work, when I press enter the input data dissapear and machine dont move. It does not show up in history popup window either.

I run the 2010 screenset, and mach version .066.

Could it be an ebay pendant i tried a while ago, but quit using, that might have messed up some hotkeys or similar. I am really out of ideas here.

I have been away from the machine for a while, and cannot remember when this stopped working, so hard for me to relate it to new version, pendant, 2010 screenset install, hotkeys or similar

General Mach Discussion / Mach3 6 Axis USB Joystick Rocker Electronic Handwheel and 2010 screenset
« on: November 10, 2015, 12:26:01 PM »
Hi

I purchased one of these controllers for mach 3, but I have problems getting some functions to work with the 2010 screenset.
Everything works with 1020

Do I have to assign anything, or use some screendesigner to assign these.
Only the axis jog works in 2010.

General Mach Discussion / Feedrate override makes machine stutter
« on: September 29, 2015, 02:41:01 PM »
If I try to cut a circle (R65) with a 6mm endmill at 1500 mm/min there is no problem. I can run the same code at 6000mm with no problem.
BUT, if i run the code at 1500 mm/min and use feedrate override at 200% (F3000) it "stutters" (shakes) at the all the 90 degree point of the circle (where x and Y mixes).

The machine shows that it can handle 6000 mm+, could it be that its my computer having problems calculating and sending the pulsestream in the parallel port when using override?
Its not a very fast computer, but the mach 3 test tool says it can handle 35khz, and the software is set to that.

any ideas?

G-Code, CAD, and CAM discussions / Move after program end
« on: September 01, 2015, 04:01:59 PM »
After spending some time searching the forum, I cannot seem to find an answer to my problem.

When I machine at an offset, lets say G55, and the program ends, the machine moves to "0", but this position puts the gantry and spindle somehow in the way of my inspections or removal of the machined piece.

Is there a way to make the machine go the the machine coordinate position, or any specified position automatically after program end?

Mach Screens / Out of the box Simple Screen for New project w/Mach 3
« on: May 15, 2015, 05:57:51 PM »
I have not used any screedesigner in 3-4 years.
I am starting a poject, that is a little out of the box.
I want to make myself a Tigerstop for my chopsaw.
Single stepper axis with the posibilities to have a screen with a large numeric display to enter the position/length of the board
The speed will be constant, just tuning the motor ramp in config
I am planning to use a touch screen, if possible.
So if anyone want to fiddle with a screenset for fun, it would be greately appreciated.
