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

« on: November 24, 2017, 07:40:15 AM »

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

G-Code, CAD, and CAM discussions / Re: UC100 G02 will not work

« on: November 23, 2017, 02:38:32 AM »

Hi Al,

I am not sure the explanation you received from UC100 has any credibility or not – It certainly seems strange to me.

You need to look at your ‘Mach3 plasma.scpost’ Post Processor as a matter of urgency – it is not preparing the Mach3 Gcode correctly (at least not as Mach3 wants to see it) and it is creating errors.

Perhaps the most important change to make is to have it place the G91.1 on a separate line (certainly not on the same line as the G90).

Try placing the G91.1 on a separate line and see if your UC100 works correctly then.

Mach4 General Discussion / Re: XHC Mach4 USB motion board warning and info

« on: November 22, 2017, 04:53:17 AM »

Hi Peter,

Thanks for the heads-up on the XHC USB.

There are probably for and against debates about any motion controller  - I use the ESS.

So when updating Mach3 does it retain all of the settings?

If you install the new version over the top of the existing version then yes all the settings are retained. However, it always pays to keep a copy of your existing Mach3 folder just in case.

My workshop PC does not connect to the net so I download Mach on this PC then copy the installation.exe file to a USB memory stick then use that to transfer the installation.exe to the workshop PC.

Sorry but Digitizing is not something I have ever done so can't be much help regarding reduction of the Z axis clearance move.

I think you must be looking at a very old version of Mach3.

As far as I know the Wizard replaced the menu version many years back.
