Hi! I was reading about this situation with these kind of motors. I think that maybe is necessary to apply this mod I need to have this clear before deciding to buy RAMPS + Pololu or start thinking in other option for electronics. Thanks..by Biomech - Stepper Motors, Servo Motors, DC Motors
Hello everybody! I have a couple of questions. I have some steppers and I can't find the datasheet, even from the manufacturer. Maybe the motors are a little old (although mine are new). The label says: 89.908.001 PAS STEP: 1.8° R: 0.7Ω U/Ph: 1.68V Crouzet They looks like a NEMA23, but slightly different. The "front" is 56x56mm, 47x47mm between holes; depth is 40mm. The shaft is 19mm long, 6by Biomech - Stepper Motors, Servo Motors, DC Motors
Well, yes and not. It's a RepRap concept at the end. AFAIK, Tantillus is the only machine that actually can print itself entirely. with the exception of rods, bolts and bearings, all the parts can be printed in the same printer. When I spoke of a basic kit, I mean something that just barely be able to print, from scratch, every part of the machine (with the exception of the extruder, that it is nby Biomech - Tantillus
Yes, I think I got it. my problem is that I have different motors and I am impatient to start building my printer. What if I put a resistor in series with the motor winding? For example, 0.5 Ohm (5W), this would give ... 1.68V / (0.7R + 0.5R) = 1.4A might it work? Watching how Tantillus can "evolve" from the laser-cut version to the all-printed version, I was having the crazy idea of a printerby Biomech - Tantillus
I have been consulting with the pillow, and I think it's best to make the machine as it was designed, so, to avoid problems I will get the NEMA 17 motors. thanks for the comments.by Biomech - Tantillus

Hello everybody! I've been following this project for a while since I like the design of this printer, it's simple, yet it gets high quality results. Well done Sublime! Now that I am fully determined to make this machine, I am putting together the necessary parts. Although I have some experience with electronic and mechanical components, I am going to need a some help, and I wish you could pointby Biomech - Tantillus
