Are you able to provide an 3d part assembly drawing (solidworks, rhino, spaceclaim or other) of the machine for those of us that may need to redesign to suit the parts or fabrication methods we have available to u...

- Are you using CW? Which version? - After slicing can you click on the view gcode and email me the contents, or put on google drive or box or something? - Also feel the stepper driver on the controller board with a finger during a print (ground yourself on something metal first, like a t-slot leg),...

You should be able to change this value by $2=400 in the GRBL console window, and will...

Thanks for the interest, I don't have any plans to put new batches of kits in the webstore and my main focus at the moment is to support existing customers / provide help with the open source project. Inventory depletion / lack of available time / and increasing number of low cost lcd based printers...
