At 3 amps, in microstepping modes, the power transistors on the Linistepper will get very hot. It is your responsibility to keep them cooled down enough that they don't burn out. In full or half step, heat will be much less of a problem.
A lot of people have run the Linistepper at 3, 4 or even 5 amps, but they used CPU fans or very large heatsinks and they tested it carefully under all conditions before they left it running. All the details on how to tune it for higher amperage are at: How to use it, and keep it cool!' at: '' ediestel@pol.net asks:
I would like to use linisteppers to drive Vexta pk246 motors with encoders. They are 3 amp/phase in unipolar mode.|Delete 'P-' before: '' but after: ' you sir are the most epic of all children EVER!!!! come have fun times with me and my monkey :)
When ordering the kits - 4 axis - can you provide the parts that are needed for 3amp/phase operation as part of the kit ?
The description of use for higher amps sounds hesitant; do you advise against it ?
Is there a detailed post from someone that runs a 3 amp/phase motor with this card ?
I have become very interested in your Linisteper kits. I have some questions, I intend to build a small(24"x24"x48") 4axis foam cutter, mainly for my RC aircraft hobby. I found some nice looking motors and as I am truly a Newbie thought I'd ask to make shure these motors would work with your Linisteper design. I know the Linisteper only works with Unipolar motors, can these motors be configured as unipolar for the Linisteper? I have sent the seller this question and have not recieved a reply. Also in your opinion would 30.0 oz-in "cut it" I'm only going to move the gantry and wire.'

Any help greatly appreciated!
