OK - that sounds smart, but now a bigger question is about hooking up stops and limit and home switches.

I am running Mach 3 and my board is a TB6560 like in this picture:

James - to zero the Z axis, to lower the bit down to the stock. Right now I jog the axis with a sheet of paper underneath it and zero it out when i can't move the paper. I thought the hand crank...

I picked up a pack of knobs at radio shack today, put them on - but it is really tough to turn the motor while it is powered...is there a setting or button in Mach3 I'm supposed to switch to allow a...

It seems like the option for Drawing units only allows either inches or MM...does that mean that if i was to pocket a 30mm circle using a 1/4" router bit, I need to do set the Drawing units to either...

Hi Larst - how did things end up?

Gerry,

Thanks - once I looked at my Gcode and saw all these F10 and F30s, i wondered where they came from...and found them in the machine defaults in Cambam. Now I have my motors tuned to their...

I'm running a DIY desktop CNC with Mach3...dealing with very slow cutting rates because of flex in the y/z axis.

Yeah, a rebuild is in my future but for now I'm having fun making things...at 3-9...

Looks good - what is the footprint of the unit and are you following someones plans or is this your own design?

A lot of great dialog here - I've learned a lot & the picture helped me understand a bit more. I've got a lot of learning to do, but now I see that a lower RPM could be a good thing and should help....

Thanks Lou - you're right, I'm not going to get high speeds on my all thread; I think I'll get 28 to 38 IPM max...

Thanks for the detailed answer Bob.

For the width, I have it set at 0.4, which made a second pass to widen the routed profile.

Learning to use my new homebuilt CNC & tried some oak: I thought I was taking it easy until the bit broke.

Flojor10 - thanks - I picked up the 1/4" 2 flute bit (also picked up a 1/8") from HD & it's working great for my test cuts.

Martin - thanks - I've made the change and the message went away.

Target depth is -0.15 which makes 3 passes

Thanks

When I generate my tool path, I see the following note:

"changing depthincrement to be +ve"

In the machining for that shape have my stock surface set as 0 and the depth increment as -0.05

A great video here showing the Lego frame CNC cutting a face out of a block of florist foam.

I just got my DIY CNC up and running and would like to try something like that - does anyone have a...

I know this is a late reply, but I've had success with the TB6560 boaard...so far. PM me if you need some help & I'll do what I can.

Sorry if this seems obvious, but since I can't see what you have going on...are you sure the 24/36V power supply is connected to the board and powered properly? I guess it must be if you are seeing...

Are you jogging the steppers with Mach3? Using the up/down/left/right/pageup/pagedown buttons on your keyboard?

If your inputs and outputs are set properly in Mach3 (i.e. they match the...

After a bit of research I decided on the Solsylva 13x13 as my toe-in-the-water approach to building a CNC. I'm satisfied with the choice - the instructions are very clear, and I've learned a lot.

This picture reminds me of the nursery setup from a pair of proud parents to be, awaitng their bundle of joy to arrive.

After a bit of research I decided on building the Solsylva 13x13 fixed gantry CNC. The project is moving along well enough and I am definitely learning a lot.

I chose a small machine as a starter...

I think I might get what I need by cutting the end off the handle and threading it (M8 -1.25) and using a coupling nut to connect it to a piece of M8 threaded rod.

Seems like a $20 solution to a...

Tx - thanks, I see how that could work. I guess that would complicate the setup and breakdown for each use, or I'd need to leave the shaft permanently installed, which would be a little klugey. ...

Tx - interesting - so you think just slipping them in? I wonder if they'd stay fixed or if I'd need to epoxy them.

I have a manual pasta machine that is powered by a hand crank, like the one in the picture below.

I want to power this machine to make it easier to use. I have an old drill, a router speed...

I saw on buildyourcnc that the guy mounted the PS, BoB and drivers in a wood letter tray. Looked like a neat solution but I don't have a letter tray sitting around, so I'd need to buy or build...

Thanks for the answer and the video...great setup you have too!

if running a diy cnc, using a laminate trimmer as the spindle:

1) when you plan a tool change in the toolpath, does Gcode automatically raise the spindle and await manual input that the tool has...
