Hey guys... Me and the kids are wanting to build our first 3D printer, however i was originally going to build a DIY CNC so I have some stuff left over from that. I already have quite a bit of stuff that accumulated towards a DIY CNC Mill so might as well put it to use! I have 4x Applied Motion STM23Q-3AE Yes I know... Its complete overkill, but I have it sitting here collecting dust so why not actually put it to use! As you can see the motor already has a driver built in but it can run on either step by step or SCL SCL would be nice as it would reduce the amount of wiring required and since the units are programable its and easy to implement with a use of their 4 or 8 port router/switch boards... Input please !! https://reprap.org/forum/read.php?219,304133,304133#msg-304133 Mon, 16 Mar 2026 07:36:34 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,304133,304334#msg-304334 https://reprap.org/forum/read.php?219,304133,304334#msg-304334
Looking closer at the SCL interface, it appears to be RS232 at 9600 baud on the model you have. I don't think that would be anywhere fast enough to provide real time control. In a CNC device you could probably program a series of moves via the Hub program with a small pause between, but with a printer any pauses lead to blobby prints. I am not sure how to coordinate multiple axes, I guess that must be possible in the Hub program.]]> bobc RAMPS Electronics Sat, 01 Feb 2014 07:25:34 -0500 https://reprap.org/forum/read.php?219,304133,304218#msg-304218 https://reprap.org/forum/read.php?219,304133,304218#msg-304218
How many wires will be running to each motor ? 5 or 6 ?]]> _Adrian_ RAMPS Electronics Fri, 31 Jan 2014 20:56:24 -0500 https://reprap.org/forum/read.php?219,304133,304194#msg-304194 https://reprap.org/forum/read.php?219,304133,304194#msg-304194
I would go with the Step/Dir interface.]]> bobc RAMPS Electronics Fri, 31 Jan 2014 19:16:15 -0500 https://reprap.org/forum/read.php?219,304133,304133#msg-304133 https://reprap.org/forum/read.php?219,304133,304133#msg-304133 Me and the kids are wanting to build our first 3D printer, however i was originally going to build a DIY CNC so I have some stuff left over from that.
