Probably the consecutive call for mcToolPathGenerate() method is causing this error.

Any ideas?

Finished Screens / AI Helped Custom screen
« Last post by tgirard on March 30, 2026, 05:41:13 PM »
I just wanted to show what One person, working with ChatGPT could accomplish.
The Problem: The customer has a Laser Engraving system but the aperture is small. They lave large graphics and need a way to move the laser into multiple positions and execute the laser program. Each position may need tweaking and or Laser power and speed setting changes. [/img]

The Solution: Using AI and Lua I was able to create a solution whereby you create a .csv file that has all the picture names and settings you want. You then place the images in the bitmaps folder I created at the root level of the Mach4 folder. Then you simply open the csv and the images show up on the screen, You can click on each image and the individual parameters show up. You and set things automatically and then generate the actual GCode that will move the table to the center of each image and send the Laser commands via the Lasers API. I could have NEVER done this on my own. however with ChatGPT helping me every step of the way, I was able to build this out, Have the code completely commented, Have everything about the project organized in Git for future updates and All within a very reasonable amount of time. I still have a bunch to do but it's really been much easier with the AI helping. I Know I'm probably helping with the destruction of the developemnt industry and that sucks but I feel like I'm a way better LUA programmer now and that's gotta count for something. Let me know if you have any questions

I get this error almost every time I click the "View Toolpath" button in canned cycles.

Mach4 Hobby Lathe
Mach4 4.2.0.5036 (latest)

Is there a fix or workround?

Thanks

Most 3 wire probes are normally open when they touch the material, the signal pin is pulled low or high depending on your board.

Mach4 General Discussion / Mach4 keyboard inputs
« Last post by patton on March 30, 2026, 10:19:43 AM »
Hey Everyone, Iv'e been trying to figure out how to make keyboard inputs work with buttons like Block Delete, Optional Stop, and setting Z Zero. This is for a lathe... I tried doing it the same way as Feed Hold, or Cycle Start but It's not working. I would think that it's possible to do this but I'm just not a programmer. Iv'e searched the forum for this but haven't found anything helpful. If anyone can help me figure this out, I would greatly appreciate it.

Thanks
Dave

Mach Screens / A way to grow or shrink the font size in the Gcode control
« Last post by tgirard on March 30, 2026, 01:31:23 AM »
I just wanted to pass this on. Maybe it's totaly comman knowledge. if so feel free to close this. the GCode display control doesn't really adhere to the font size you select. Depending on how big/small the control is, the text can be huge or super tiny. there is a way however to control it somewhat. It's through the 'Lines' property. Depending on how many lines of gcode you allow to be displayed, the font size will adjust accordingly. Try it out and see for yourself. I just wanted to say in case it wasn't common knowledge

General Mach Discussion / Re: Mach3 / Win10 and UC100

I am sure the UC100 will enable you to have another 10 years of trouble free machining.

Just for reference, the instruction video for installing the UC100 USB drivers with Win10 / Win11 is here;  http://www.szentkereszty.net/uc100/

Thanks Tweakie.
I used to be right up on all this stuff but lost track of the details while happily machining along for the last 10 years.
I ordered a UC100 from their website. It appears they don't complete orders on the weekend?? All I got back was an email saying they would notify me. I guess tomorrow (Monday) will tell.
Thanks

HiCON Motion Controller / Re: Legacy Syil X5 with Hicon 7754 controller

If anyone has the files and can attach them to a reply I will greatly appreciate it. Tried the wayback machine archive but vitalsystems requested to be excluded from it.

Received this reply from the company which is contradictory regarding the files needed...
"Sorry I cannot find the old document.  We do have the old plugins and firmware and some mach4 screens.  They are available for purchase on as-is basis without any warrantee or support.  If you like to purchase them, you can buy the Bronze support package and will email you the files."

I replied if the files are available without support but got no reply yet.

Thanks a lot
