I am working on a design that requires 2 Y motors. Since my Ramps 1.4 board only has pins for one Y motor, am I safe in simply splicing together both Y motors and attaching the spliced connection to the Y pins on my Ramps board? Or could this cause accuracy issues?

Most of the time it works, but sometimes it does not.


id be running the printer and checking the current on each motor to make sure they are both drawing the same current, if not one is working harder than another, and could be out of sync or becoming less efficient operation, motors could have slight differences... make sure your using the exact same motor
you can run parallel brushed motors on the same controller and brushless- but sensored brushless might not work at all

also im sure these controllers would have power limits, the fets can only handle so much current.
You might need to run extra cooling on your controller.]]> nechaus General Fri, 16 Aug 2013 05:15:56 -0400 https://reprap.org/forum/read.php?1,236173,236569#msg-236569 https://reprap.org/forum/read.php?1,236173,236569#msg-236569
Using that method you get the most power for your motors. Connecting two steppers to one controller is not a good idea, in my opinion. One Pololu or StepStick cannot supply enough power for high torque use.]]> jkoljo General Fri, 16 Aug 2013 04:51:42 -0400 https://reprap.org/forum/read.php?1,236173,236480#msg-236480 https://reprap.org/forum/read.php?1,236173,236480#msg-236480 en.wikipedia.org]]]> jamesdanielv General Fri, 16 Aug 2013 03:11:23 -0400 https://reprap.org/forum/read.php?1,236173,236438#msg-236438 https://reprap.org/forum/read.php?1,236173,236438#msg-236438 panly557 General Fri, 16 Aug 2013 02:39:23 -0400 https://reprap.org/forum/read.php?1,236173,236201#msg-236201 https://reprap.org/forum/read.php?1,236173,236201#msg-236201
