EMC2's sample stepper config comes with "standard-pinout.hal" and xylotex-pinout.hal", and all you have to do is invoke one or the other from the ini file.

Re: [Emc-users] Low end stepper driver controller?
Many small drives for that current rating are designed around the Allegro 3977, which is a single chip driver with an integrated translator. It can handle up to 2.5 Amps at 35V with appropriate heatsinking. If you really want to roll your own you can download the spec sheet from www.allegromicro.com but the last time I googled "allegro 3977" at least one kit supplier came up. If I remember correctly they also sold bare PCBs. Any 3977 based product should work with EMC. Xylotex makes drives based around the 3977 but they have discontinued their single channel unit in favor of a 3 and 4 channel units. I've got a machine with a Xylotex 3-channel drive that runs fine with EMC, but I think I had to do something with the pinout. It's been a while but I think I had to swap some pins around. I hope that helps!

Re: [Emc-users] Low end stepper driver controller?
Jack, I have drivers for bi-polar motors. See: http://www.probotix.com/stepper_motor_drivers/SideStep And just to be fair, you should look at the Xylotex & AlienCNC drivers. You will also find a number of other bi-polar drivers on eBay. >Len -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jack Sent: Saturday, May 26, 2007 9:02 AM To: 'Enhanced Machine Controller (EMC)' Subject: [Emc-users] Low end stepper driver controller?

See the integrator's manual which describes how to use it. The manual may be slightly out of date regarding the available inputs, so use halcmd/halshow to examine them on a running EMC2.

[Emc-users] Control Panel for Axis
I plan on wiring momentary push button switches in parallel with the appopriate short cut keys on the keyboard. One of the problems I see is that of providing for the 2 key combination required for the Home-All function. I assume that the key assignment can be changed in software and hope someone can give me insight into how this could be done.
