Advice on motor-motherboard combonation Ok so I'm trying to build a large Delta style printer like the Kossel. They use and sell a Ramps1.4 kit. Designed to work with Nema 17 motor of about 2.8 volts. My distance is greater and my effector platform rods are a little thicker and longer. But still carbon fiber. So I dont want to give of the speed that these delta machines usually have. so my question is this. what is the limiting factor with using the "Under 3V" NEMA 17 motors specified by the REpRap Wiki? For instance, at 12 volt Nema would offer superior torque and speed would it not? would a kit like this : [www.builda3dprinter.eu] work with a 12V nema 17? What changes would have to be made? would this require customer steppers and or RAMPS kit to be made? would be grateful for any advice! Thank you in advance. Not sure if it is relevant but would like to use [www.mattercontrol.com] for running and managing the printer. https://reprap.org/forum/read.php?13,445705,445705#msg-445705 Mon, 16 Mar 2026 10:40:55 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,445705,446058#msg-446058 Re: Advice on motor-motherboard combonation https://reprap.org/forum/read.php?13,445705,446058#msg-446058

What board would you recommend. Keeping in mind the printer type "Large Delta" and Software solution "MatterControl"?

Sorry, I don't know the "MatterControl" software, so I can't advise you. Given a free choice of software, if the motors you choose are happy with 1.2A or less, then I would choose the Duet board - but that's because I am writing the Delta firmware for it! Unlike most Delta firmware, it will generate the steps accurately instead of approximating each stepper motor movement as straight line segments, which may (or may not) improve print quality.

Other 32-bit solutions I am aware of (but have no experience of) are the Arduino Due + RAMPS-FD, and the Smoothieboard. But the Arduino Due doesn't have Ethernet, and AFAIK the Smoothieboard doesn't either.

Smoothieboard does now have Ethernet on them Smoothieboard

There is also the RADDS on due which will run Repetier firmware]]> dougal1957 Controllers Sun, 21 Dec 2014 03:19:33 -0500 https://reprap.org/forum/read.php?13,445705,445973#msg-445973 Re: Advice on motor-motherboard combonation https://reprap.org/forum/read.php?13,445705,445973#msg-445973

Again, Thank you very much for your help and insight on this matter.]]> calmasacow Controllers Fri, 19 Dec 2014 18:16:26 -0500 https://reprap.org/forum/read.php?13,445705,445718#msg-445718 Re: Advice on motor-motherboard combonation https://reprap.org/forum/read.php?13,445705,445718#msg-445718
I suggest you choose stepper motors rated at around 1.2 to 1.5A, because that is about what the low-cost stepper drivers can provide without too much extra cooling. The motor datasheet will specify the torque, allowing you to compare different stepper motors. Then choose a supply voltage of 12V if the winding voltage at max current is 3V or less, and 24V if it is between 3V and 6V. This is only a rough guide, because ideally one should determine the maximum step rate needed, then read the winding inductance off the motor datasheet, and do the sums.

btw I wouldn't choose standard RAMPS or any other 8-bit Arduino electronics to run a delta, because the 8-bit processors barely have enough power for this application. I suggest you choose 32-bit electronics.]]> dc42 Controllers Fri, 19 Dec 2014 18:10:09 -0500 https://reprap.org/forum/read.php?13,445705,445705#msg-445705 Advice on motor-motherboard combonation https://reprap.org/forum/read.php?13,445705,445705#msg-445705
