Tangent Corner / change (Linuxcnc step/dir-servos) to Mach3 to suit recipient. Obsolete pcb

« on: May 26, 2024, 10:42:43 AM »

It seems that my documentation is lost, I'm too old , and Company who made the p.c.b is no longer around, I think because web site domain is for sale.
The p.c.b is a p.w.m input to analog 0-10 volt output.
Web page silk is screened on board says "www.kdntool.com   DCNC/VFD/OPTO REV1".

If someone has a schematic for this p.c.p could you please email it to me?
With thanks,

I'm giving my converted Grip1340 G ball-screw converted lathe to a friend whom I was unable to convert to linuxcnc. He's a Mach lover.

Attached 1 only photo of the obsolete item described.

Show"N"Tell ( Your Machines) / A wizard I wrote for a local rim repair shop

« on: March 10, 2023, 12:21:01 PM »

Re-drilling bolt circle holes is, apparently no fun using custom 1 inch drill bit. Not a lot of height above wheel face to bridgeport-like mill.
A few years ago, my neighbour and Rim Repair shop owner asked if I could mill the bolt circle hole and "while I'm at it" machine
a tapered seat so new inserts could be pressed in.
Knowing nothing about wheels, I wrote him some code in 'G-code' that he had no chance of editing. So here's what I came up with
after a very long time.

VB and the development of wizards / The M40 opendigfile Macro in Mach3

« on: December 01, 2022, 12:48:32 PM »

Circumstance: Using Mach3 digitize wizard in mach3\addons directory results in gcode file and when cycle starts,  a dialog box pops up looking for a filename and a path to save to probe data. This box is quite small and often the operator doesn't look at the path. Screen is 5 feet away above tail stock of large car wheel lathe where we probe then re-cut the faces.

I would like to assign a windows path so the user doesn't need to look at it since it is always  the same provided no-one , like me , came along and changes it.

Solution -  I'd like to add a line ahead of the code"M40" macro file such as  "SetSaveAsPath = "c:\users\Billy\Desktop\DigitizePatterns\2022"
so when the daily user runs his probing the M40 dialog box will pop up with destination already set.

The trouble is, I do not know the variable name for the path string. In the XML file it's called <Pattern>. No such luck using that.
name.
Any ideas where I can find the correct variable name for this path variable, or perhaps another solution.?
