NEMA 17 Rated Current Question
Can anyone tell me best settings for:
Rated Current and Microstepping

I can see why you are stuck and it's a bit naughty of E3D not to publish the rated current IMO. There is a web address pointing to a pdf at the bottom of the link you posted, but the pdf doesn't show the rated current either. E3D describe the motors as being custom made for them so I guess your only option is to email E3D (unless someone on this forum has that information). I use a similar motor but it's 1.8 degree. 16X micro stepping with interpolation works well for me so I see no reason why that wouldn't work for the 0.9 degree motors too. Steps per mm for me are around 405 so to get you going (assuming you are using them with a Titan extruder), you should start with around 810.
Thank you, i will try to contact e3d.
The one I have from E3D has Motech MT-1701HSM140AE written on the side. I can't find a datasheet for this precise model. but I found the MT1701HS140 listed at http://www.motechmotor.com/products_detail.php?id=140&cid=62&page=1 which appears to be the 1.8deg version of the same motor. The length and phase resistance match too. In which case, the rated current is 1.4A.
Thank you for answer. Its 1.4 A, i set E1260 in config. Temperature 62c max. Works perfect.
