I would suggest downloading a free trial of a 'real' CAM program such as CamBam. Draw a simple circle in that and generate the GCode. If that does...
I'm no expert, but the pololu website suggests putting a multimeter on one of the pins going to your motor (i.e. measure the current across one coil)...
Lucky you didn't fry it :)
Quick tip for cable management. Well worth getting some of this...
The power supply depends on what spindle or router you are using and what driver board. For example, the protoneer cnc shield can accept between 12v...
Breach plug grease? That sounds like something you'd use on a submarine. :) Thanks for all the replies. I'll start with some 3 in 1 and see how I go.
I got a 8mm screw and ant backlash nut from QTecStore on ebay....
Yes, you could. There are lots of options for electronics, including the TinyG, the gShield and the protoneer CNC shield. All three are good choices...
Back with another question. What are people using for lubricant on their leadscrew? A specialist product or something more general?
I like the flexi shaft spindle on your site, but 43W seems a little light even for wood. How does it perform on a routy?
Great job. I would prefer a thicker z axis if you are going to put a lot of weight on it though. Maybe even a double gantry plate somehow? Some of...
Cheapest I can find in the UK is closer to $10.
Thanks, I don't really want to buy a dedicated tap and die for just a couple of holes, but I also know that pretty much every screw I have used has...
Can you tell me what type of screws you used for the ends of the z-axis v slot? Did you tap them separately or use self tapping screws? If you use...
I have the same as you, but haven't busted out the soldering iron yet (got an unassembled board). Good to know it works fine.
Eeek. My spindle is 800g! I also think that any spindle worth it's salt is going to be at least 400g
Great job.
For cutting foam I doubt the stiffness would matter. I would think it would be fine.
Very cool. Life got in my way this weekend, so I couldn't get working on mine. Nice to see one one the way to being finished.
I think you were using the DRV8825 drivers? In that case you will probably want to turn the current limiting pot to limit the current to just about...
