I will be using a Nema17 27:1 geared motor which required 12VDC. But I'm a bit confused by the images on the cloudynights discussion. I wonder if you happen to have any images of your kits? The 12VDC input and the connections to the PC would help too.

Hi Peter,
happy to help. I'm using the same motor as you, one thing that I found was that the motor became very hot when running at 12 volts (despite it's spec) so I dropped the power to 6 volts. The motor still has heaps of torque, but barely gets warm. Works a treat.
There is also a line in the firmware that may ned changing depending upon the display you purchased.
PM me your mobile number and which parts you need images of and I will
sms pics to you
cheers
Gary
