Hi Chris,
By the way what's the purpose of this video? I didn't see the final milled PCB.
Kindly show a video with SMD tracks and pads or just one you milled lying around.
How deep does the...
You are spot on Roger, 35uM = 0.035mm.
When stepper feedrate is high one ends up copper whiskers or burrs.
I can easily manage with mill 0.3mm PCB tracks with 20º 'V' bits 0.1mm tip, remember...
Just curious, why would you need a four axis CNC to mill a PCB?
I know post is a bit old.
Cheers,
Hanspeter.
Hi Miki,
Here are my GRBL settings, but careful not to copy everything as my stepper direction in my settings could be different from yours.
Should give you a starting point if you are over/under...
Hi Miki,
Let me point you to a site with member's using exactly your CNC machine for help.

I must agree spindle runouts is a nightmare for milling precise PCB's, but we all have slightly different out comes with DC motors with ER11 chucks,
below are pictures to prove otherwise.

Hope you might have resolved your issues but take a look at this site,

Have been using OpenCNCPilot for four years and never looked back. https://github.com/martin2250/OpenCNCPilot
I can mill 0.3mm tracks on a warped PCB as OpenCNCPilot is an auto-leveling open...
Hi Craig,
I thought this thread is in connection with Re: Which bits to use for PCB milling? so newbies don't get the short end of the thread :)

Kernel,
I understand you're concern with milling a copper clad board hence your measurement area.
Drills and measurement looks ok from where I'm sitting :)
Hope you marked that area out so you...
If both axis are running on lead screws, just ensure it has anti-backlash nut installed and working.
I'm assuming your CNC is Hermes V3400 engraver.
How do you hold PCB on the bed?
double...
The short answer, your CNC could be loosing steps.
Did you follow CitizenOfDreams guide?
Hi Kernel,
Have you read some of the solutions given under the thread https://www.cnczone.com/forums/pcb-milling
Remember to provide a picture of your CNC setup, such as stepper controller,...
Hi Wayne,
What's the size of your steppers? Is your Z axis fitted with a plasma touch? from post #893 or do you only do plasma cutting?
If yes then I recommend replacing your Toshiba TB6560AHQ...
Hi RCaffin,
I totally agree with you.
I had times to return these cheap V bits as the tips range from 0.1mm - 0.3mm for a 0.1mm bit.
Perfectly understand the Chinese aren't meticulous, for...
You are spot on.
15 years ago I was dreaming of buying an LPKF CNC from Germany, I almost wasted my money.
Bought a ball screw CNC on Amazon for $600.
Cheers.
Hi RCaffin,
Indeed, but must say these end mills are expensive comparative to 30° 0.1mm V bits from Amazon these are very
affordable and disposable too.

Hi All,
Although an old thread I would like to put to rest the misconception of milling a PCB on a Chinese CNC machine found
on Amazon or elsewhere.
Below is my CNC machine.

Congrats durango100 that's fast thinking of your solution! but did you first try installing a baffle on either side of the fan
such that picture you posted in the end, FAN will be seen with two flat...
Looking back,
1. Am inclined to believe these Chinese has gotten the business model right, else why
will we still be buying/falling for these controllers in the first place?
2. It's also...
To start with, PCB track layout to/from TB6560AHQ or TB6600HG base controllers on some if not all of these Chinese
sources are not well though out.
But I want to believe the whole point of this...
The TB6600HG has all the improvements lacking in TB6560 and yes of cause without startup sequence describe in the
TB6560 tech. manual as this is automatically handled on TB6600HG.
My good guess...
Hi All,
Have said all here and on USB CNC forum, these PWM chips are from Toshiba and noting wrong with the chip
design it's self and at the time. Toshiba has a replacement for TB6560 PWM chip...

Which of these boards do you have, the Red or Blue solder resist?
Do remember that the PWM chips are from Toshiba, I hope these are not Chinese bootleg.

Hi Nigel,
You have such strong passion to do just this the first time?. Most of the time these gizmo's don't work straight out of the CAN.
