If you did, you wouldnt have to ask.

 

You guys are killing me. I am 152 miles away from mine so I can't look. To rub salt in the wound, I got an email about it today challenging me to find it.

 

Congrats on cracking the code!

There's numerous debate threads on microstepping in the forums. They go into great length. Here's one: Micro stepping Myths and Realities For more, do a search, but I think that one will answer your question.

As far as the jumpers go, it does certainly look like they are both open. Peter will get eyes on this and be able to address this.

 

Its definitely set to 1/8th. Theres a little track under the black soldermask on the appropriate jumpers


1/8th gives the perfect power-to-resolution balance for most of our users on most of our hardware.

Higher microstepping: quieter motors, theoretically better resolution, but much decreased torque.
Lower microstepping: more torque, a little more noise (like you are gonna hear the motors over the sound of the router hehe) and less theoretical resolution.

Note re resolution. Only single steps are precise. Microstepping is an approximate interpolation between physical steps. It was actually designed to smooth out harmonics, not increase resolution

 

If you really did crack step 1 its just a clue to the next step (there are several) which will lead you to a point where you wont need to ask How or Where... Its 100% clear if you did crack all the steps

 

Well the point of this is a treasure hunt, so cant really tell you step by step right?

Your doubt means you havent figured out step 1... If you did, you wouldnt be asking what to do. Youd know. So check again, you maybe only have half?

 

Email? Theres no email involved in the process
So you sure you did the whole thing?

[edit tested the whole process myself a few mins ago and its works as planned... if you did complete the process (all the secrets) and it didnt give you a code, PM me and we'll see if we can figure out why]

 

Grbl only allows one set of configurations.

Of course you could set the settings each time you switch to another machine, but that sounds like a schlep. I'd personally prefer a controller on each machine. All the reconfiguring, replugging, etc may just cause a lot of unplanned wear and tear

 

Yes it is

 

Mine came in today! The question is, is there an Easter Egg on this one leading to the gold plated BlackBox.

 

1. Or just rely on the fact that we went through all the maths and then stacks of sample motors, and then years of proving them in the field, to test a combination that performs optimally, and get some of our NEMA 23 Stepper Motor - High Torque Series - which would be the best most powerful motor to use with this setup. In fact BlackBox was designed to suit the motor, not the other way round)
2. It is 4A Max (peak, for a couple fractions of a second) and 3.2A RMS (continuous): ie look for motors around the 3A mark

 

BlackBox comes preinstalled with Grbl.

All you have to download (one of many options, but aimed at beginners) is OpenBuildsCONTROL from OpenBuilds Software - FREE Software for CNC Control: OpenBuilds CONTROL and OpenBuilds CAM

Workflow:
1. Draw in CAD
2. Export to SVG or DXF
3. Open in a CAM program or OpenBuilds CAM Gcode Creator - Public Beta
4. Use CAM to setup toolpaths and export GCODE
5. Open GCODE in OpenBuildsCONTROL
6. Connect to controller, jog to origin of material, click SetZero, then run the GCODE
