General Mach Discussion / Re: how to configure mach3 closed loop spindle control

« on: November 27, 2017, 02:01:49 AM »

if relying on the index pulse (once per revolution) even if Mach could close the loop its going to be that slow
to respond that it would still be unusable for lathe threading.

Sorry Craig but not quite true - there are many lathe users threading this way.

It's a fair bit of reading but you may find the Members Document on Coordinate Spaces of interest as it relates to your questions and desire to learn. http://www.machsupport.com/forum/index.php?action=dlattach;topic=33595.0;attach=46569

General Mach Discussion / Re: Mach3 changed my Z settings by itself!

If you are just starting out then I would recommend Mach4 (it is the future). You can download and install / run the full version of Mach4 Hobby free of charge - it is run-time limited but it will give you a good idea of it's capabilities. If you are satisfied then purchase the license to unlock the time limit and away you go

Mach4 General Discussion / Re: Mach4 trial fully functional?

Mach3 has been a little buggy lately, losing steps, dropping my soft limit settings, etc.

That is not a fault of Mach3.

Your steps per unit should remain the same (assuming your machined dimensions are correct) but reducing the axis Velocity and Acceleration of your Z axis by 50% (and saving the changes) may help. But if it is lost steps (as Gerry suggested) reducing the Z axis feed-rate may also help.

If you can repeat the problem then the DRO readings from the Z axis will tell if it is lost steps.

EDIT: Just read your post in the Mach4 section and if you think the problems you are having are bugs within Mach3 then please think again and perhaps read the Mach3 manual.

Tangent Corner / Re: Optical Illusion.

My Hungarian friend just copied my posted picture and then used Photoshop (or similar) to do the copy and paste. He did say that he could not believe his eyes so all credit must go to E.H.Adelson for creating such an excellent and reproducible optical illusion.

(I have to admit to being a bit dis-loyal but the Gcode was generated and the image laser produced using the Auggie / 57CNC Tempest planner and motion controller).

By way of proof, a good friend of mine in Hungary sent me this picture. He has copied a section of the A square and pasted it by the B square and done a similar thing with the B and A squares to prove that my laser etched shades of the two squares are indeed the same.

When the cutter sank deeply into the salvage board what did the Z Axis DRO read ?
Did the Z axis DRO show the correct Gcode dimension ?

Hi Matt,

The STB4100 is for Mach3 only. To use Mach4 you need a different controller, there are many to choose from - I use the ESS and you can read-up details here https://www.warp9td.com/index.php/gettingstarted
