Re: Power Supply for TinyG

...because they'll hardly ever move at top speed/maximum load at the same time... According to the TinyG developers, stepper motors use the most energy when they're idling, so maximum current draw would be something like when e.g. Y and Z are locked and you're moving in X, not when you're moving th...

Re: Power Supply for TinyG

Most NEMA 23 motors I've seen use around 2 amps. When you're running a job there will undoubtedly be times when all 3 axes are moving at the same time, which means you need 2(x) + 4(y) + 2(z) = 8 amps available. Typically you don't want to run a power supply at 100% of its capacity so it doesn't ove...

I've been thinking about doing the same. What kind did you get? How much do you like them?

Thanks

Re: Cash for Gcode

This is dointhangs on cherry. They both look great, I don't know which one to give him and which one to keep.

Thanks you guys for all your help and the tip about meshcam -- that looks like exactly the software I need if/when I need to do this again.

Re: DW 660 Problems

I ran the Kanji code you sent me earlier today on my DW660, I'd say it was at least 10 minutes. The bit and locking nut were definitely hot to the touch but after about a minute I had no problems swapping the bit out. Thanks @WillAdams for the speed control link -- I'm going to get one of those. Whe...

Re: Cash for Gcode

I ran danimal's code at lunch today on Birch, it turned out really well! I can't thank you enough.

I'm going to try dointhangs tonight on something else like Aspen, I will post another pic later.

Thanks again,

Chris

Cash for Gcode

Hi all, I've built two Shapeokos and am familiar with Gcode but I've never actually used CAD software like Inkscape etc. to generate Gcode -- to date all my work's been with PC programs generating the code programmatically (my pick and place machine and my new mill that makes boxes for my lights). I...

My $0.99 dust shoe

My original plan for my new mill was to buy one of IC's dust shoes because his ACME rod and Dewalt mount kits are top notch, but unfortunately I can't afford the loss of the Y axis millable space. Within the last few weeks there's been discussion on dust shoes and the drawback that the bristles obsc...
