Feature Requests / Re: steps per unit calulator NEEDS FIXING.

« on: July 14, 2020, 01:42:52 AM »

I notice that in the picture you posted you have not completed the Wizard by making the 'Incremental Move' and entering the ‘Actual Move Distance’ then used ‘Recalculate’ to show the ‘Calculated Steps/Unit’. I wonder why ?

As proof of concept I changed my X axis Steps / Counts per Unit to 336
I ran the Steps per Unit Calculator Wizard making an incremental move of 100mm
I measured the actual distance moved at 105mm
Using Recalculate it tells me that the correct Steps / Counts per Unit should be 320.0
Perfect.

Trust me Slanteng, if you are truly struggling to understand the simple operation of this Wizard then Mach4 is not for you.

Caveat;
Because Mach4 is an actively developing product it is possible that certain functions may work correctly in one development build but not in another development build therefore it is recommended and assumed that the user is always using the current, stable, version (currently 2.0.4300).

As you have discovered, there is some learning to be done with CNC but it's a great ride.

Its not hard to make a mess of a Screen.set, I think we have all done it at some time or another but just take it steady, one step at a time, and you will get there.

Then you will need to be learning the Cypress Enable subset of Visual Basic for the button codes (or perhaps initially copy from my website  )

I am sure it is not necessary but just in case you do need it here is a very basic guide…

Existing X axis steps per unit (Counts per unit) = 10000
Move distance = 1
Actual move distance (measured) = 25.4
Recalculate
Calculated steps per unit = 393.70078740157

In Configure / Control / Motors…
Change the X axis steps per unit (Counts per unit) from 10000 to 393.70078740157
Apply the change.

Run the calculator again
Existing X axis steps per unit (Counts per unit) = 393.70078740157
Move distance = 100
Actual move distance (measured) = 100
Recalculate
Calculated steps per unit = 393.70078740157

Now repeat for each axis.

Hi,

Perhaps take a look at the method I use for Tool Position Setting;  http://www.tweakie.byethost10.com/17.htm

(Use the Screen Editor to add a VB button to your screen that contains the offset between your crosshair and cutter. Clicking the on-screen button moves the cutter by that amount).

I will do my best from now on to keep my frustration away from those with good intention but no idea.

 

So you entered a move distance of 1

How much did it actually move (in millimetres) ?
Did you enter that distance in Actual Move Distance ?
Did you Recalculate ?
Did you run it again using the Calculated Steps per Unit saved for the axis being tested ?

EDIT;   Additional information…

I do appreciate that there is no comprehensive instruction document for using the Steps per Unit Calculator and a lot still needs to be added to the Mach4 manual but using the calculator correctly is surely not that difficult. If we can use it then I am sure that you can.

Perhaps watch Art’s video to see how it is used – OK, he is using imperial (Inch) measurements but please remember that the calculator operates in UNITS so all your inputs and measurements should be entered in MILLIMETRES (if they are the units you have set for your machine). Do not mix units - if you are working in mm then use mm not cm.

At the store there was a Big X by the register for me to stand on…
I’ve seen too many Road Runner cartoons to fall for that one.

Have you tried using the Circle Centre Wizard ?
