Mach4 General Discussion / Re: configure spindle as c-axis on Lathe with smoothstepper and Servo (step/dir)

« on: November 01, 2021, 04:18:19 AM »

Hello,

Does anyone know how such a setup works and who mach4 is doing this? Dont really undestand the logic behind the system in that case. I am a little confused...

What servo you have, maybe we have the same and help you with the config. Yes you can, you need to find the input setting of your servo drive to change from step/dir to pwm/rpm, at mach4 you will setup up both and you change the script to enable the input of servo when Mach4 SpindleOn command run.

Pretty much all you need to do is to find the right settings of your servo, one output from your controller to the input of your servo and one command line in the spinCW/spinCCW script.

PoKeys / Antidive feature "not working" with Pokeys57cnc and PlasmaSens

« on: September 17, 2021, 09:09:39 AM »

Hello everyone, i am searching why i can't use Anti dive feature but i am unlucky to find something useful.

When the XY velocity is zero i can change Anti dive state on/off but immediately after a movement at any speed the state goes off.

I try every setting in Adjust Rate and Anti dive rate but nothing, Mach4 has very low info on how plasma module works and don't know what may be the problem.

Does the plugin of pokeys disable antidive?

Thanks a lot

Mach4 General Discussion / Re: Mach4 with TCH3in1 not seeing voltage changes

« on: September 15, 2021, 01:35:15 AM »

Thanks, I am using the ESS and a PMDX126.  I followed that setup guide to the "T" i think.  I can get the plasma machine to pierce delay, drop down to cut hight but i'd expect to see a voltage read out on the DRO.  I don't see that.

You need to use they'r screenset or modify yours with a dro with the register from your plugin with the "actual tip volts".

I just wire up my THC3in1, added the voltage divider, know that it works because I tested with multimeter.  Tried different THC screens in mach4, but not seeing voltage changes I would expect.  Simple question, what screen shows it?  Can someone post a video of it working?

Thanks,
Jared

To see the voltage need to add a dro to the screen via edit screen with the register from your THC/plugin/controller or open Diagnostic - Regfile and go to that register.

I don't know what THC3in1 is to help you more.

Mach4 General Discussion / Re: Ease-in and ease-out spindle on M3 and M5?

« on: September 13, 2021, 05:05:42 AM »

After I read your post I searched for parameters and found ADCRiseTime and ADCFallTime. Setting these to 500ms did the trick.

Thanks.

You are welcome, glad that you solve it.

Hi,

My spindle motor is an AC servo and it is driven with 0-10v analog. Currently the servo does hard start on M3 and hard stop on M5. Is there a way to setup Mach4 to increase the analog signal from 0 to the desired speed like 500ms so it'll kinda soft start and vice versa?

Thanks

That should be easy to do it from your servo drive settings, check the manual. I don't think that you can do it from Mach4.

Mach4 General Discussion / Re: Current Position not updating

« on: August 30, 2021, 10:28:09 AM »

The problem I have is when I jog any of the 3 axes, the DRO for Current Position doesn't change at all, but the Machine Coordinates DRO updates live as you would expect.

I don't know if will help you but that happened to me on other dros few times. I make some changes to screen and suddenly a dro not updating, restart mach4, restart pc nothing help.
I delete the dro and put it again and then it work, if i recall right one time i delete and put it twice to make it work.

Mach4 General Discussion / Mach4 THC registers info?

« on: August 24, 2021, 09:52:00 AM »

Hello everybody, i search but not find more info than the usual of plasma configs.

Is anywhere more/better explained info about Mach4 thc registers?

The most are understandable by name but still if we had more info about how the module use each one would be better.
I am looking for more info about:
DeadBandWidth
ObSetAt
MoveTimer
VelJogState
PIDdval
PIDimax
PIDival
PIDkd
PIDki
PIDkp

If anyone wonders why, i have a plasma divider that output 0-5V and i want to see if i can make any changes for my THC to work better or this is the best.

Thanks in advance

Mach4 General Discussion / Re: Can't save edited screen load script

« on: August 22, 2021, 06:39:16 PM »

That did the trick! Cycle start button is working.

Here is what I ended up with.

[mc.ISIG_INPUT0] = funtion (state)
    if (state == 1) then
        Cyclestart()
    end
end

Thank you for taking the time to help. Much appreciated. Now I have a few other things to fix and I will be able to start making parts!!

No problem, wish you the best!

I assume I should change mine to match yours?

Right of "Screen load Script" where says "pageid=0" if you click once with the mouse will get some "..." click there and will open the editor of load script.
There you will make the changes you want
