The linisteper works great. I am very pleased - question though. I have another project that needs 5amp's how would you requmend steping up the output. I guess the Heat sinks would be huge - I could use fans, I could use a dalenton high current maybe TIP41C?. What do you suggest - Boots-2b1

|Insert 'You can use the form about half way down the page at http://www.piclist.com/techref/io/stepper/linistep/lini_tun.htm to find the sense resistor values to use for your target motor current. I'm a little confused as to why you feel the other resistors must be changed...' at: ''
I would aappreciate a little help. I intend to use a 2.7A motor, but is aware that tnhe the sense resistor cannot be lower than 0.66 ohm. I understand that R14-R17 has to be changed, and so do R18-29. Have tried various values, but it's it been really a shot in the dark. Could you be able to suggest some values are starting point.
Thank you for your help and a agreat design
Kind regards - Jock
