strange coincidence, I was just thinking about this last week. except I'm thinking Arduino based hardware and was also thinking about monitoring...
If you want to try something really old you can look at TurboCNC. This runs on DOS so you have to jump around a bit to create a machine that boots to...
nasty! were you driving? I did 2 years of (conscript) service, more than enough for me thanks. my father served in North Africa in WW2, captured at...
accuracy,resolution,repeatability similar words that mean different things, particularly for CNC machines. so.... accuracy DEPENDS on resolution and...
if you use belt/chain/cable drives, you DO need microstepping (unless you have some sort of reduction between the motor and the belt drive, but even...
you need to replace all those servos with metal gear digitals. this will give you much higher resolution and smoother movement, though I suspect...
The file is just fine, and gplot.exe opens it for me. The problem is your national formatting settings (a Windows setting under...
this forum software is broken, I cannot find the WANT button! :)
Please post the .skp file and the .cnc you generated so I can look at them.
another option is to move from GRBL to a better USB based board like Planet-CNC or TinyG. also note that when wiring emergency stop buttons, they...
usb to parallel converter WILL NOT WORK what you can use is a PCIe parallel port card that plugs inside the computer like this...
as I understand Gcode programming, you should not be homing within your program. Homing is something you do after machine switch on, before you run...
Radio control stores will have RPM meters for measuring prop rpm, they should be good to about 30000 rpm. what you will need is a short flat blade...
I do :) environmentally friendly or not, it has nothing to do with whether or not it is the correct cutting coolant for the material being cut. We...
yes no. chip load is how much each tooth cuts off as it passes, and is governed by the rpm and feed rate. 'plunge depth' is not the same thing, this...
chip load per tooth is 'how deep each tooth cuts' and is recommended by the tool maker. normally in the range of 0.002 to 0.008 inches for...
A series of videos on connecting, testing and calibrating CNC electronics.
Please do not guess at feed rates, this is science not art :) Feed rate calculators are all over the web, use them. an example,...
How about making your own cable guides with your router? [media] I've never had water causing cracking in acrylic, but alcohol will do it for sure....
from what I have read the colored lasers go through the clear plastics, only infrared will melt it, sometimes. my idea is to 'color in' the surface...
