Mach3 under Vista / Re: Help with STEPS PER UNIT CALCULATOR

« on: October 05, 2018, 01:44:03 AM »

Hi Sono,

The most common microstep setting is 8 (or 1/8th).

The Gecko website has some excellent explanatory tutorials; https://www.geckodrive.com/support/step-motor-basics.html

So if I understand it correctly, if my Ballscrew is 12mm diameter and 4mm Pitch and it has one start, Lead (mm/rev) value on the file should be 4, right?

Correct

Hi ,

I see the confusion.

'Pitch' is the distance between the crest of adjacent threads and 'Thread Starts' are the number of individual threads.
Basically the calculation provides the distance the carriage moves from one complete revolution of the screw and this is defined as the 'Lead'.

You do not have to complete the lower part of the calculator to obtain the Steps per Unit.

Once you have established the correct Steps per Unit they can be checked by using the Axis Calibration feature on the Settings page.

I am pleased that you have sorted the Crop Circles 

If you run the Axis Calibration feature (Settings page) you can check that your Steps per Unit are set correctly for your Y axis (use a reasonably large distance when testing).

To remove the Crop Circles;  In Config / General Config change the IJ Mode setting. Then Regen the toolpath and all should be well.

Ideally all Gcode containing arcs should contain the correct G90.1 or G91.1 (as appropriate).

Hi Mike,

From your earlier photo it appears that you are using the ESS Port3.
Ideally you should be using Port1 (which has the standard LPT parallel port pinout) because Port3 has bi-directional pins 2 - 9 and this may be causing your problem.
