Hi kawfree,
If you need quicker support you can contact us directly on our support email address as we only check the forum occasionally. Your encoder counts sounds correct and you have verified it...
Hi,
Yes the EA and EB lights will flash when you rotate the encoder shaft. Check you have the +5V and 0V supplying power to the encoder and the A and B encoder output wires connected back to the...
Hi,
Your control electronics need to be electrically isolated from your power electronics otherwise you will have noise and safety issues. The +5V for the drives control section and the +15V for the...
Sorry for confusing you, I didn't explain it very well. Your encoder connection in the previous diagram was correct. The four encoder wires should go DIRECTLY to the 0V, +5V, EA and EB terminals on...
Hi, Yes that's correct. Both the Viper and Machdrives BRB have 5V TTL Step/Dir inputs so wiring is the same.
Masso S+ and D+ to STEP and DIR on BRB,
Also don't forget the control ground between the...
Looking good. When you have the encoder wired up and apply the 5V you can use the Tuna DRO screen to verify correct operation by moving the axis by hand and checking the displayed distance matches...
No problem. Let me know if you need help connecting the BRB to the Masso controller as I can help with that as well.

Hi Ned,
Wiring your encoders up to out BRB servo drive is as follows. All connections are to the blue terminal block.
Encoder GND to BRB "0V"
Encoder +5V to BRB "+5V"
Encoder A+ to BRB "EA"...

Hi,
Yes you can use a direct connect type driver module that accepts logic input signals from the LPT port but then the bridge and motors share the same ground as the printer port. As you are making...
Hello,
Yes the thing you are missing between the LPT port and the stepper driver is called a breakout board. It buffers the LPT control lines and provides enough current to drive the PUL, DIR and EN...

Noise aside the spindle motor should be earthed for safety reasons in case of a motor winding short to the metal housing. A metal hose clamp around the body with a decent gauge earth wire could be a...

Hi Ken,
I am also in Australia and have access to a large range of electronic parts. Let me know what replacement bits you need and if I have them I will send them to you at no charge. It doesn't...
This is now sold.
Thanks to everyone for looking.

Hi Marty
Thanks for the information. Am I correct that you have a Tormach 1100 with generic Leadshine 3ND883 drives? I see these are 80V with a current rating of 8.3A peak and 5.9A RMS. Also the...
Hi SwampDonkey,
Yes you are correct, our dual encoder drive only works with brushed DC servo motors. You would need to swap out the stepper motors. Do you think there would be good demand for a...
Although this solution didn't exist back in 2015 when Dave Lawrence asked this question, you can now get a dual encoder step/dir drive for Mach3 that takes linear glass scales as the second encoder...
As you have eight leads, each of the two phases is split into two windings. You can wire these in serial or parallel to match your driver capability.
Here is a good reference on the different...
This is now sold. Thanks to everyone who had a look or bid.
