Sorry, I didn't explain very well what I was meaning.

Keyboard Jog is at the % rate set in slow jog.

MDI jog or G00 is at the full 100% rate.

Still not sure if I have explained what is in my head.

Hi Fernando,

Sorry but I forgot to mention that George Race is a member of this forum so you could PM him for his input.

FAQs / Re: Axis Limits in Toolpath screen

However, during a program cut, the brushes on my Porter Cable Router bit the dust. Does anyone know of a local supplier for the 869659 Porter Cable motor brushes? As I understand it, that part number is a generic part number which replaced the original Porter Cable part no31652. Any suggestions?

Sorry to hear that your spindle expired, but this is bit of an international forum so where are you located.

Man phones swimming pool and asks if he has got through to the local swimming pool. Reply was "It depends where you are calling from")

If your slow jog rate is set to less than 100% could this have a similar effect ??

Hi Lou,

Welcome to the forum.

It sounds to me like your motor tuning may need adjustment.
In Config / Motor tuning - set your velocity to something like 1000 mm/min and use the up/down arrow keys to test the setting. if it then works, save the setting and proceed to the next axis.
Once all axis are working then you can fine tune the Velocity and Acceleration settings of each axis for best performance / reliability.

Hope this helps.

Hi Fernando,

The Burt Rutan planes are something else and always seem to explore the edges of known technology and science - I think you would be taking on a lot to attempt to follow his lead without having expert aerodynamic knowledge.

A guy who would be good to talk to is George Race - His homebuilt Zenith CH-701 was just expertly constructed, he also documented the build with lots of photos and comments etc. What he doesn't know about homebuild is probably not worth knowing.

So how exactly have you wired the breakout board to the 15 pin connector ??

Steppers sound fine (the 8 wires would either be connected as 2 parallel sets of windings with 6 Amp capacity or two series connected sets of windings with 3 Amp capacity).
The Gecko drive controller is certainly not the cheapest available for your project but is is perhaps the easiest option which is well documented and has excellent after sales and back-up etc.

Your existing power supply should be Ok so the hardest part would probably be re-wiring the stepper motor plug connections to suit the new controller.

Hope this helps.
