General Mach Discussion / How to synchronise two encoders
« on: December 27, 2020, 12:01:30 PM »
Hi guys, just thinking about projects for next year and I would like to make a power feed (roller wheels) for a mitre saw.
The catch is that I want one set of rollers on one side of the saw and then a second set on the outfeed. Both sets to be synchronised as the timber passes from one set of rollers to the other.
Assuming the encoder was mounted on a roller-table, how can I pass the value of one encoder at the point that the timber reaches the second set of rollers?

Hope that makes sense!

Yes, I have the 12v connected, the external relays and 0-10v speed control all working great.

Has anybody had any luck with this, it would be nice to find a solution using the 5-axis bob and not having to buy another one.

Yep, but my signals don't get through the bob.

Hi guys, I have been trying to setup Mach3 to accept an encoder so I can thread on the lathe using the ESS.

If I wire the encoder A/B to the Chinese 5-axis bob then MAch3 does not get any signal. If I wire the encoder A/B direct to the parallel port, bypassing the BOB, it works a treat. The BOB is over here -https://warp9td.com/images/BOB_Vendors/StepperOnline/ST-V2.pdf

Has anyone else noticed this and is there anything I can do to prevent it from happening? I have tried a 4k7 resistor from 5v to the inputs but it doesn't help.

Any ideas?

Unbelievable, I was just driving home and heard on the radio that one of the kardashians has released an app showing how to eat Reece's pieces!

Got it sorted, I forgot to switch on the internal power supply VDD-COM

I am stuck, I have a Mitsubishi MR-J2S-70A which I have just fitted as the spindle on my old Denford Triac mill, I have conected it up to a CNC4PC C41 PWM drive board nad have a nice 0-10v signal going into the drive via Mach3.
I have wired SON, EMG, Limits to GND on the CN1B socket of the drive along with the 0-10v and signal ground pair,  but upon power on I just get AL.06 which is EMG stop.

I have set the params according to the manual but there must be something I have overlooked.

All ideas welcome, Jason.
