reprap stepper motor control system & arduino system does it work to control the 3 axis cnc machine they sell parts for at the RRRC? https://reprap.org/forum/read.php?14,19875,19875#msg-19875 Tue, 10 Mar 2026 12:12:43 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?14,19875,21803#msg-21803 https://reprap.org/forum/read.php?14,19875,21803#msg-21803 KaiBackman Mechanics Sat, 28 Feb 2009 00:13:37 -0500 https://reprap.org/forum/read.php?14,19875,21623#msg-21623 https://reprap.org/forum/read.php?14,19875,21623#msg-21623
The components supplied in the kits could be a limiting factor.

The cct was based on a 5v & 12V supply from an Old PC switch mode PSU, using the 4 pin molex D connectors as used in HDs & CD drives.

So you may need to adjust the values of R8~R10 to suit the voltage of Vss

You must check that the maximum voltage of C2 is adequate for the new supply voltage. An electrolitic capacitor given a higher voltage than its rateing is very dangerous.]]> BodgeIt Mechanics Fri, 20 Feb 2009 19:06:45 -0500 https://reprap.org/forum/read.php?14,19875,21620#msg-21620 https://reprap.org/forum/read.php?14,19875,21620#msg-21620 nophead Mechanics Fri, 20 Feb 2009 18:04:18 -0500 https://reprap.org/forum/read.php?14,19875,21613#msg-21613 https://reprap.org/forum/read.php?14,19875,21613#msg-21613
Reprap is a kind of CNC machine that deposits material in stead of removing material.

The MCwire design or any of the small CNC designs on Instructables.com could be driven by the RRRF electronics. The steper motors from the RRRF would be ideal or need to be of a similar spec to the motors specified. The stepper drivers can only contoll steppers that use up to 2A per winding with a voltage less that 12v .

This is why the electronics are only sutible for a relativly small CNC machine.]]> BodgeIt Mechanics Fri, 20 Feb 2009 16:00:40 -0500 https://reprap.org/forum/read.php?14,19875,19875#msg-19875 https://reprap.org/forum/read.php?14,19875,19875#msg-19875 josheeg Mechanics Tue, 30 Dec 2008 16:21:35 -0500
