CNC Spindle Update

Hi All, Ive just replaced the motor on my spindle to get get more RPM, before I was getting around 10,000RPM, for drilling PCB with the small drills is not really enough, increasing th spindle speed will also allow me to increase my feeds. So I swapped out the motor with a brushless 3650-2050KV moto...

Re: Favourite Blogs and Maker Sites?

hmmm too many to list. every time I find an interesting site I add the feed to my feedly list and it gets categorised so is rather large. Main reads currently similar to BJ's some key other ones from memory These are purely Makerish in nature and then I have heaps of others for robotics, RPi, 3DPrin...

Re: 80W Chinese Laser Cutter Commissioning

Over the weekend I installed a beam combiner A beam combiner is used to combine visible red laser pointer with the main beam so the red dot appears on the surface of your work and can see where its login to cut. The Chinese laser cutters come with a laser pointer connected to the head and adjusted s...

Re: CNC PCB calibration

Here are couple more zoomed out on the feed and speed test pattens based on procedure outlined here m I start of at 50mm/min @50um (0.050mm) depth of cut then increase the feed speed by 50mm/min each time up to 400mm/min, then do all again for both 75um depth and again at 100um depth.

Re: CNC PCB calibration

Here you can see that the fine tipped V-Bit does not like faster feed speeds as it starts to deflect and not cut properly, sort of bounces over the surface.

Here is a list of resources relating to milling your own PCB via CNC m open source CNC controller supporting GRBL and TinyG controllers, this is something you load the GCode into and then it sends to your CNC device. Ive tried both GRB and TinyG. TinyG seems more supported and has some more features...
