Here are some questions in my mind and want to ask or confirm before building my Tantillus:
Motor
Model no.: 42BYGH40-402A
Step angle: 1.8°
Length: 39mm
Rated voltage: 3.15V
Rated current: 1.5A
Phase resistance: 2.1Ω
Phase inductance: 1.9 mH
Holding torque: 3.0 kgf.cm
Lead wire: 4
Rotor inertia: 54 g.cm
Weight: 0.28kg
I am not so sure this motor alright for Tantillus which I am going to order. Does it have enough torque?

J-head/ hot end
Seems I can only get MKV (worst case may get MKIV) instead of MK Vb. Looks like there are no sizes different but will I face any problems if I just use MK V? (Planned to use 1.75mm in feed and 0.35mm nozzle)

Power supply
BOM : 90 watt power supply (15V @ 5/6A)
I have an old ASUS laptop transformer (Output: 19V @ 4.74A) and want to use it to power up my Tantillus. However the supplier for my ramps and mega said the D1 pin on ramps will not be soldered and told us the buyer to give both circuit board separate power supply. I am not sure is this the situation you guys having when building Tantillus and could I just solder them in parallel (or even add some resistance) so I can use my old laptop transformer to power up everything?

Hobbed bolt
I am building metric 1.75mm Tantillus. Due to lack of tools I may not able to make my M8 X 110 into Hobbed bolt. As previous post mentioned 1.75mm in feed doesn’t need to craft so deep, is it possible don’t even craft? Or is there any alternative method I can use?
Thank You
Cow

What level are you setting the fans at? Some DC fans don't like being driven by a PWM, and will only work at high duty cycles (~100% or 255 on the LCD). There was a thread on here somewhere about using an RC circuit to convert the PWM into a pure DC voltage, which might make the fans happier.

Thank you all, i just set 255 in the firmware as fans just work on that.
I am facing another issue that when i click home button the Z will go down ( about 10) instead of going back to the original position. Is it because i just connect only 4 pins instead of 8 pins of the Z motor? How you guys connect them?
Thanks!
