Mach4 General Discussion / Touch/corner finding

« on: January 17, 2019, 03:28:28 PM »

Hi everyone,
I have a touchplate and want to corner find from the inside edges rather than the outside.  Currently when I go into the settings for Touch, the only option available is Outside with Z.  Is there any option available for Inside with Z? 
If there isn't, how can I enter the size of the touchplate, as without it, it cannot find the corner properly (or at least it doesn't seem to).  The height is there, but width option is not.
Thanks
Mike

Mach4 General Discussion / Mach4 Hobby Autotouchplate function

« on: January 15, 2019, 05:19:56 PM »

Hi everyone.  I have a CNC Router Parts 4896 Pro machine with the Plug and Play ESS electronics package.
I have everything working wonderfully in Mach3, including the touchplate and a diode laser for engraving.  I run Windows 7 and no issues whatsoever with Mach3.
I am trying to move to Mach4 for the improved laser functions. 
I am running into a few issues, the current main issue being Auto Zero functioning with edge finding.
In Mach3, the script will find the top of the material and the corner automatically (although it only uses the X+ and Y+ sides rather than finding the actual centre, as it has the width of the plate programmed in the script.)
However, in Mach 4, it will not work properly.  If I do a Z only, it works fine.  If I find the centre of the touchplate only, it works fine.
But when I try to find the bottom/left corner with Z, it will do a Z probe, retract, do a Y- move, make contact, then move Z to the touchplate and stop with an Error: Unexpected Probe Touch message.  The history file reports:
" Z axis is performing a touch move.ESS: Successful Probe0 Strike.  Probing finished.Z Axis Offset Set to: -1.1236220472441.RetractingY axis is performing a Level 2 prep move.ESS: Successful Probe0 Strike.  Probing finished.Z axis is performing a Level 1 prep move.ESS: Successful Probe0 Strike.  Probing finished.ERROR: Unexpected probe touch".
Given that the single functions work fine, I'm guessing there is some sort of error in the script, but I am not a programmer. 
Any help please?
Thanks

General Mach Discussion / Go to Zero not working Mach 3

« on: November 13, 2018, 11:03:11 AM »

Hi all,
Having a problem with the Go To Zero button in Mach3.
It worked up until about 2 weeks ago.
Now when I hit it, the Z-axis lifts until it hits the limit switch, then triggers and stops.  It never homes X or Y.
I have changed nothing and no updates have been done.
Any ideas?
Thanks
Mike

Mach4 General Discussion / Mach4 demo will not load

« on: July 25, 2018, 02:56:28 PM »

Hi all.  Using a Dell Inspiron laptop to take a look at Mach4 to see if I want to upgrade from Mach3.  Its an 8th gen I7 with 16GB RAM and Windows 10 Home.  I also tried it on a Microsoft Surface Book with I7 6th Gen with 16 GB RAM.  The demo will just load the screen fro selection of the profile, then, after selecting a profile, the screen disappears and nothing loads.  I'd tried running in Admin mode, turning off BitDefender AV, but nothing seems to work.  Most telling is that it is doing it on both machines.  Is something wrong with the latest Demo?
Thanks
Mike
