Air cooled spindles are usually 300 Hz (18 000 rpm) max but also have lower minimal speed than the water cooled. Can't remember the exact value.

Hi scorch,
Trying to migrate to Linux as much as possible. Installed the dependencies and ran the .py file (Ubuntu). And surprise - it works :)

No, motors have drivers. Mach3 is in a way motion controller but wholly in software which uses a standard PC. A motion controller is a stand alone hardware device with its own CPU which receives...

I don't know how the spindle is mounted but one can always get creative and find a way to mount a different one. Searched the web but found only one video with D200 and the mount is not visible well...

Hello Mihai, from the near neighborhood :)
I am in Bulgaria.
Haven't been in a while on the zone ahd have missed this excellent thread. I've been thinking recently about using a DC brushed motor as...

You need to learn the basic G-codes and M-commands then write a simple program in Notepad and load it into Mach 3.
Or, use the MDI window and enter appropriate commands one at a time manually.
But...

You can't have a reliable glitch-free motion control under Windows >98, i.e. multitasking OS. Or a special very high priority driver is needed (like the one Mach3 uses).
Need to boot into pure DOS...

metaparts - Revision 384: /trunk/metadrill

there you can see some code and description of he method

As scorch says flipping is easy using pins to fix the PCB at the same position. That's how I do double-sided ones. All you need is at least two pins with centers on one of the PCB center...

Works like charm, scorch! :cheers:
Did 2 identical and relatively large (90 x 150 mm) PCBs with 2 different tools - 0.2 mm tip for contouring and 0.5 mm tip for clearing based on a single surface...

Thanks for the update, scorch.
I'll give it a try on first job that needs surface height correction.

Sent you some files, check the junk folder :)

Is there an IDE to design the GUI or you code it manually?
I am really impressed by the size of the source code and the functionality.
There is a similar program in Java but no visual...

For me, making it able to split the process and work with saved to a file probing data will be more than enough at this very moment :)
I did some digging into the code but my command on Python is...

I've done some thinking over the strategy. As I see it:
1. G-code Ripper (GCR) reads a G-code file the usual way as it is now. The user sets the probing grid like now. Then there is a new button...

Great effort and a lot of coding has gone into this program.
In my practice a different case has arisen. I am trying to engrave a logo on a plate which is roughly a sphere cut out. Probing went fine...

@alevitt53
Are you saying that you drive each ballscrew as a separate axis (X an A)? And how did you even manage to make it under Mach3?
If this is the case it is not correct. You may use two...

What is your drive screw pitch? Check eventually whether this pattern occurs at the same step.

What controller/driver are you using?

If you try CamBam and need assistance you can find me under the same nickname in their forum :)

As I wrote, I'm using CamBam.
I make the PCB layout with DipTrace, export to Gerber format and open it in CamBam, Its interpreter makes smooth curved polylines and in actual process the router tool...

Hi Marcus,
I am not familiar with GitHub so I'll post a code snippet with the changes I made, they are really simple:

private static String getInterpolatedZ(double lastX, double lastY,...

Hi Marcus,
this is a line from the console when an exception was thrown.
-1.9984014443252818E-15=lastX(0.259999999999998)-minX(0.26)
Note the underlined value. For all practical purposes it is a...

I'll try to find the exact occasion it happens. When looking into the generated file there are several subdivisions (commented) but at some point the program has stopped. I'll try to see why.

I am using Mach3. Have LinuxCNC installed but not so familiar with it. It can be done actually in Mach3 using its scripting language but I have written only simple scripts and do not know the...

Thanks, I was afraid this is the case but hoped there was a workaround :)

Yeah, I had to manually search/replace the plunge speed as 25 mm/min is too slow.
Also, another direction of expanding the program would be to save in some way the probed variables and read them...

Hello Marcus,
I tried your Java app and it worked right on first try.

Hi, today I had a meeting with this WeiHong DSP controller trying to help a person who bought a router from China.
There was no documentation about drive screw pitches and stepper microstep...

Judging from the screws on the pulley and their disposition it's a standard ballnut with standard flange (for fixed mounting) and its cylindrical part is mounted on bearings in that machined aluminum...
