has anyone tried G wizard it looks pretty good. heaps of people really
like it and the guy that makes it BOB is a diy cnc guy himself
I learnt a lot about cnc when I was first starting reading his posts on his
website

It’s common practice to have a fan on the ‘cold end’ of the print head to keep
the heater and motor from prematurely softening the filament.

Yes, electronic CAD and mechanical CAD have already merged some years ago.
Even with free software.Take a look at the gadget I made in the link
below. I designed a PCB in KiCAD and had the boards made in China then
imported the 3D model of the PCB into Fusion and used that model as a

105F is about 40C. 40C is fine for PLA.
If you do have heat issues, the first solution is to use ABS plastic as it
can handle temps up to about 90C. and I hope your motor never gets that
hot.They also make a glass-filled nylon that is even stronger when
hot and very stiff and hard
There is another way to isolate an analog control. Use an LDR. A
light-dependent resistor. These act like normal resister but change value
depending on how much light is shining on them.Ages ago in the 1960s
people would package them in a tube with a light bulb then you have an

If it is a KBIC speed
Chris, would think you would be able to connect the 0-10v output from a BOB
directly to the controller middle leg output of the potentiometer. You
wouldn’t need the hot leg, but would likely need to ground the bob to the
controller.
