Rating of Suppliers CNC Component.
Hi Everybody, it´s great satisfaction made part this comunity, i´m learning much about CNC universe. Special Thanks to Gerald the mastermind this comunity. I created this thread with purpose of rating the suppliers and their product quality.
*please Gerald delete this topic if it exist. I would like to know the views of the community about this product and supplier : http://www.longs-motor.com/productin...12_86_173.html 4 Axis Nema 23 stepper motor 425 oz & Driver DM542A CNC (for use in my MM project) 2. stepper motor driver--DM542A DM542A is a type of two-phase hybrid stepping motor driver, The drive voltage of which is from 18VDC to 50VDC. It is designed for use with 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter and less than 4.0A phase current. This circuit that it adopts is smiliar to the circuit of servo control which enables the motor run smoothly almost without noise and vibration. Hording torque when DM542A run under high speed is also significantly higher than the other two-phase driver, what’s more, the positioning accuracy is also higher. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, and computer embroider machine, packing machines and so on. Features: l High performance, low price l Average current control, 2-phase sinusoidal output current drive l Supply voltage from 18VDC to 50VDC l Opto-isolated signal I/O l Overvoltage, under voltage, overcorrect, phase short circuit protection l 15 channels subdivision and automatic idle-current reduction l 8 channels output phase current setting l Offline command input terminal l Motor torque is related with speed, but not related with step/revolution l High start speed l High hording torque under high speed 3. Power supply: The power of this power supply is 350Watts, and the output voltage/current is 24VDC/14.6A 4. Breakout board: Description: • Built in DB25 male connector. • DB25 Output Pin:P1,P2,P3,P4,P5,P6,P7,P8,P9,P14,P16,P17. • DB25 Input Pin: P10,P11,P12,P13,P15. • DB25 GND Pin: P18-P25. • Power supply: +5V DC. • Built in C-class Optical-coupler. • High quality with Surface-mount Tech This item includes: 4 pcs Nema 23 stepper motor with 425 oz.in 4 pcs stepper motor driver DM542A, peak 4.2A, 128 micsteps, replacing M542 1 pc Power supply 350Watts (24VDC/14.6A) 1 pc Breakout board & 1 pc Parallel cable |

Spend some time reading the forum & you will find why NEMA 23 was excluded.
But if you insist on using NEMA23 mators for any reasons, please do let us know of the result. |

What´s mean Nema 23? it´s a standard? Do you know a specific thread that talk about this? Thanks.

NEMA 23 references the the frame size of the stepper motor.
The MM design utilizes NEMA 34 frame size motors - 23 is not recommended. |

Thankyou Sean
What´s of the requirements of configuration (specs) more utilized (common) in a Mechmate (mark, model)? Sorry for my stupid questions, but it a only for effects of comparison. Thanks. Last edited by slobato; Fri 28 September 2012 at 10:56.. |

Thats easy, just go to the section in the forum that you are interested in, and look at the "Sticky" threads at the top. These are usually the ones you need to read first and refer to often for a particular section.
