I don't but I'm sure someone will come along who dose...

Can you not measure it to get an idea ?

Just found this from Andy Con on another thread, he mentions 3mm here for the pitch, I've sent him an email asking him to come and confirm for us :), for now you could try 3mm then :)

dscrew is 3mm pitch (1 rotation moves 3mm) waiting to get exact pitch from denford forum
Microstepping is 1/10 (stepper drivers are set to 10)
so:No. of steps per mm is = 200 * 10 * (1/3) = 667
Any ideas @andy_con ?
