Current Hi/Lo setting?

[krsykes23]

I'm confused with the Current Hi/Lo setting in the Output Sign as configuration.  I think I'm right in saying that it can limit current to the motors until actually required, which assists in keeping them cool?

The bit I'm confused about is what pin do I assign it to and where does it go!  Does it only relate to driver boards that have a specific function to reduce the motor's current and have an appropriate pin?

Apologies if it's a stupid question!

Keith,
What drives are you using? Post info on them.

can limit current to the motors until actually required, which assists in keeping them cool?

No, usually done with a switch / resistor  on the drive .... but if you post info about your drives surely someone will take a look to better help you out.

Hi Rich,

Thanks for that.  I'm only using a very cheap and probably low quality 4 axis drive board, based on the TB6560.  Whilst it's at the lowest end of the quality scale, it's perfect in getting my
new machine 'up and running'.

You set the current for each axis using the dip switches on the board and the max current setting is 3A per axis.
What current setting you use depends on the motor rating and  how it is wired.

Keith,

You may find the info presented here of interest  http://www.savebase.com/infobase/downloads/TB6560/TB6560_4Axis_Driver.doc

(the RepRap is wired differently to any CNC router and so has different pin assignments)
