HI Tom,

I have Servo-Tek Single ended. I replaced the cable with one that has twisted pairs individually shielded. With the shield tied to digital ground, my counts are now perfect for big open...

Hi Tom,

Looks like a big part of my problem is noise on the encoders.

I have encoder 2 hooked up and watching the digital screen while I slowly turn the motor by hand, I get the two bits...

Hi Tom,

I have had problems with the forum always logging me out when I am half way done with a post. Then it acts funky when you use the "use auto-recover data" link below the reply box. ...

HI Tom,

I understand about zeroing the servo. I will be sure to do so before each trial. It sometimes takes a few clicks on the zero button to get the position all the way to zero on the axis...

Sorry images are so bad. Having trouble with the forum editor today.

Hi Tom,

Changing input0 to bit 2 gives me counts.

with gain 0.025 as you suggest I get some output...

Hi Tom,

The data sheet says 500 Pulse dual channel

Channels are labeled
A-Channel, 500 Pules
B-Channel, 500 Pules

I seem to get a correct speed reading for spindle speed using an...

Hello Tom,

I have been using a setup with stepper motor open loop in microstep mode with decent success for a while.

I am attempting to add a shaft encoder and to use CL-Micro mode.

I have...

Shucks, Mach4 looks like it would be a great upgrade!

Hi Tom,

I put a little routine in the spindle call thread that changes the InputGain. works perfectly even responds dynamically during G-Code speed change!!

Hi Tom,

I have done as suggested. I get good readings now.

Given that my machine is a bridgport, I have a gearbox for low range that is downstream from the encoder.

Is the rpm data separate...

Hi Tom,

I had it close. I just used axis 4 instead of axis 3 in the threading section of the plugin config!

So now, I have an awesome display of speed.

There is no obvious scaling factor...

Hi Tom,

So I have revised down my expectations for the time being.

I have close to success using a tapping head now, but have trouble setting my spindle speed very well as the feed back is only...

Hi Tom,

Successfully making parts now with this machine!

Already looking to upgrade to do tapping.

It has a 2hp Induction motor currently. I could get a VFD for it. Or I could get a 2hp...

Thanks!

Hi Tom,

This changed produced beautiful results.

Mach3 now will jog to the motor resolution.
I have two original motors from the mid 70s. Along the way I became convinced that my Z motor was...

Hi Tom,

My CAM really wants to use G91.1 any plans to add support for it in KmotionCNC?

Jake

,

No good clues from KMOTION except the destination replicates the Mach3 behaviour of moving once and then not updating destination. There is every time an audible bump.
Flushbuf does not help....

Hi Tom,

Issues still exist with mach3 and small moves. It will job 0.001" one time only/ Then the motor just bumps forward and back a tiny bit but no movement. Also does not update DROs in...

Hi Tom,

The updated DLL seems to have fixed the problem!

What about soft limits and positive limits? Should they be set in both Dynomotion and Mach3?

Happy day,

Jake

Hi Tom,

So after finding the ground loop problem, interference was vastly reduced, but still did the overcurrent thing.

So I replaced all motor cables with shielded 5 conductor cables. Shield...

on the Mach3 homing i FOUND THIS


That part is good.

Thanks,

Jake

Tom,

I believe that I still have interference problems. I have shielded cable to run between motors and SnapAmps on the way. Currently they run from all motors in a bundle with no shielding. ...

Hi Tom,

I am happy to report much improvement on a few fronts.

The major issue is solved. As you have suggested several times while helping, the issue was interference. By chance I had the...

Hi tom,

New Snap Amp installed.

System is noticeably more stable. However, My Z axis still sometimes goes into the overload condition during homing. (it never does it while jogging go figure....

Tom,

Thanks!!

I really do like your stuff a lot.

My company is a 1.1 person company.

Happy day,

Hi Tom,

The Dunk Dunk Dunk, is a problem in that the stepper definitely looses count.

Typically though as soon as that behavior starts, the other axis go into overload. Most times after that,....

Tom,

Grounds are indeed disconnected internally.
I installed a jumper to the other one. It might have helped a bit, but the problem still keeps happening.

Unfortunately, I did have the...

Hi Tom,

i fixed those code things.

Thanks, I like clean code. Didn't help though.

So here are results from another experiment you recommended.

Disconnected SnapAmp#A (SnapAmp#A is the...
