General Mach Discussion / Puzzled :(
« on: June 05, 2020, 11:15:49 AM »
Yesterday I started to machine paper phenolic 4mm thickness.
At first try I had drifting to the +X direction (unfortunately did not check x0y0 when that happened.
On second try, drifting was in +X and -Y direction.
On third page it can be seen that I changed machining strategy by first drilling holes inside vectors that had to be cleared from inside. Holes were spot on. inside contour, again, was incorrect.

Gave up for now, but I'm still puzzled because machine is GAINING steps (moving gantry, steppers, belts).

Any ideas?

Forum suggestions and report forum problems. / Registering to forum Captcha sucks
« on: April 09, 2019, 03:07:39 AM »
As per subject.
Captcha should be more complicated one. I just logged off, tried to register a couple of times, just to see how easy is to create an account. It was enough to click on "I'm not a robot" and ... spamer goes through.
Hope that someone will fix this problem (NFS)

G-Code, CAD, and CAM discussions / Excellon to GCode converter - Protel
« on: September 30, 2018, 07:10:59 AM »
Since I'm using Protel for all my PCB design (from DOS versions up to 99SE) I needed a way to extract coordinates of pads for drilling to be able to drill my boards on small CNC router.
First versions were written in Quick Basic, but nowadays these programs do not work under 64-bit OS-es.
So, I rolled up the sleeves and wrote this one (links attached).

For converter to generate correct G-Code files, you have to follow following:
Excellon files must be in format - imperial 2:3 or metric 3:2 WITHOUT zero suppression (leading or trailing)

http://zastos.com/ConverterSetupC.exe - Creates folders C:\ProtelConverter and C:\ProtelConverter\Converted
http://zastos.com/ConverterSetupD.exe - Creates folders D:\ProtelConverter and D:\ProtelConverter\Converted

Output files are named Drillxx.tap and number of files depends on number of drills defined in Excellon file, and are located in ..\Converted subfolder

Converter maintains its own .ini file where relevant parameters are read from / saved to.

If anybody finds any nuances, let me know.

Of course, Converter is free for any kind of use.

General Mach Discussion / Moving part origin
« on: April 19, 2014, 06:25:28 PM »
Happy Easter everybody!

I have an Chinese made router, distributed by IEHK (www.iehk.net) that, a week or so ago, I converted from pendant controller RZ********* to mach3 control.
Just to mention, I'm an electronic guy so I made my own BOB (original pendant has differential outputs, so the BOB that I made is converting LPT port Step and Dir signals to differential ones).
Today, I started a job which is 350 x 450 mm and has 7 roughing passes and one finishing.
After tool change for a finishing pass I've noticed that my origin has moved approx 0.4 mm per pass, approx 3 mm in total, both in X and Y direction. Haven't been by machine all the time, but I guess that the move occurred after every pass.
Machine is servo driven with 2.2 kW water cooled spindle.
Could not figure what caused this moving of work origin.
