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

Thanks a lot Thomas
That is PLC code alright:)

I will try this out.
BTW, the saw build is coming along well, and phase 2 of the build will include yur genious fingerjoint jig:)

Thanks again

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

Best regards

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?

Best regards
Roy

Sorry to keep nagging here but I am trying to learn some of the VB scripting slow and steady.

I have been able to change the size of the keypad, buttons and also the placement on the screen by myself, BUT it would be great to be able to code some strings to also change the font size
Is that something that can be easily done?

Yup that did the trick. I figured that I should put my path in the ..\..\ fields. Now I am on track.
Thank you very much for your help Thomas, and I wish you a great day
