Thanks Eddy but it does not seem that easy, please could someone send me a test pcb file then I could just try it. Then perhaps buy the program.
Rusty.

Quite honestly you are better using flat-cam, its an open source app designed specifically for that task, including milling traces, routing board edges, drilling holes and cutting solder mask.

pcb milling is not cambam's strength, and it would take a lot of work to bring it up to the same level as flat-cam for that specific task. Cambam excells in other tasks, but not in this one.

is it feasible to use cambam to machine parts where the part may need to be rotated to drill or machine horizontal features, such as edge mounting holes or slots?

How do i set the rate at which the tool moves in the clearance plane?  i'm using a slow feed rate for cutting and plunging, but i would like the tool to move faster when it is clear of the work-piece.

I'm afraid it does not work for me, crashed cambam, but then I'm running on Fedora Linux. I gave up on windows over 10 years ago.

Sorry for opening an old thread

I just wanted to say i managed to sort the problem out, by re-flashing the grbl code, i think it helped not because the code was bad, but because that caused the eeprom to be cleared, now everything behaves as I expect.

On the subject of using 3D Printer controllers, i'm now testing GRBL running on an AVR 2560 using a RAMPS card, it has support for an LCD Display, a keypad and a jog wheel.

See: https://github.com/bdurbrow/grbl-Mega

Since this post have ran in 2014, have anyone figured out how to do this?

If the curvature is shallow, you can use a floating engraving tool, i recently bought one for engraving PCBs, it spring loads the engraving bit so it can float up and down.

I looking at substituting the 775 motor in my little cnc rig with a 550 and putting in a floating spindle holder that is able to move up and down.

Im new to CamBam, and CNC in general, but im struggling with coordinate systems

I have a small GRBL based CNC system with limit and homing switches fitted, and the ability to run the $H homing cycle

if i'm sitting looking at my machine from the front, looking down on the bed, the machine by default homes to the closest left hand corner of the bed, and because of backoff it considers that to be position (-4,-4). The default coordinate system that GRBL uses has negative numbers going left to right, and negative going closest to furthest, ie if i move my x position to the right hand side of the bed it will be at (-130,-4). This is apparently the default GRBL behavior and is expected, so the furthest away right hand corner is (-130,-100) based on the size of my bed.

Now CAMBAM seems to have an inverted coordinate scheme, in that the only way i can get negative coordinates is to move my work piece into the bottom left most quadrant of the drawing screen, where it is upside down and back to front.

Am i missing something obvious here, how can i align the coordinate system in CAMBAM with the physical CNC machine so i dont keep on having to do metal jiggery pokery to correct the coordinates.

I'm obviously missing something.

Ubuntu Mate 16.04, CamBam v.1 - works as it should with dragging.
As a workaround you can use copy/paste. Paste places the new copy at the end.

Im using fedora 25, and it does nothing when i release the drag.

I will play wity it some more, fesora runs in wayland, perhaps switching back to xorg will help.
9  Support / CamBam help (General usage) / Reordering profiles in a part. on: May 01, 2017, 10:54:01 am
I'm a new user with Cambam, but I have hit a minor issue.

I'm using the latest Linux version.i dont know if any of the other versions have the same problem.

I'm creating cutting profiles for cutting 4mm Acrylic. I have worked out how to create  a profile inside "Machining/Part", but i can set the inside/outside status on each profile for the profile cutouts inside the part, but i have to delete the outer profile and recreate it at the end of the list of profiles in the part, because that is the only way I can get the outer profile to be cut last.

If i drag the profile down to the end of the list, i can see the insert cursor appearing after each profile, but when i let go my outer profile jumps to the old position again, so I cant reorder the profiles to set the cutting order.
