I messed up one of the encoders. Replaced it from Digikey for $ 24.00.

Two of my encoders just crumbled at the touch so I figured to just replaced all three. I thought the originals were only 300 line anyway. Which encoder did you use? What is the resolution?

My original encoders were 1000 PPR ( pulses per revolution).

Here is a link about them:

Here is a link about the encoders:

Jog speed is very slow

Mine encoders are set @ 500 lines. MACH 3 reads quadrature encoder @ 2000 lines.

Ballscrews in my machine are 5 threads per inch.

2000 lines x 5 threads per inch= 10,000 steps for MACH to read 1 unit ( or 1inch).


Hope this helps,

This is taken from Jacks post from our retrofit. My original two encoder are 1000 PPR. I messed one up bu hooking the voltage up wrong. The new one that I got is adjustable with dip switched. I set it to 1000 PPR I also bought the wiring harness, with a plug to the encoder and a shielded cable, that I think was 6 foot long. This is the best bang for the buck.
check out the digi-key catalog.
1000 PPR = 4000 x 5 = 20,000 steps.

Jack posted earlier.

The reason I went with the AMT-103 encoder was becasue of Mariss at Gecko Drives.

Several times, I've read where people were having troubles and he would recommend this encoder and it solved their problems.

Digi-Key - 102-1308-ND (Manufacturer - AMT103-V KIT)

Also, it would be possible to use the old encoders, but there was no real step-by-step how-to on setting them up.

These Amt encoders are $23 each. I can afford to keep a spare or 2 around.

The factory encoders are like $375 each, and if you buy one off of e-bay it may be bad, too.
