THC control via XPTHC-4

Postby argeteknik » Wed Jun 06, 2018 7:24 am

Has anyone used the XPTHC-4 with the UCCNC software?

I built my own system using the UC 300EHT controller, UCCNC software and a Hypertherm Powermax 65. I also purchased an XPTHC-4 but have not been able to get it to work with the software.

The XPTHC-4 works well, meaning that it reads the Hypertherm voltage, up, down and arc relays work but I can't get the UCCNC software to control my Z axis.

some tricky points are as follows

2.1、XPTHC-4 Function
 Auto work follow:
CNC arc start signal to THC---THC start IHS first----Arc start---THC find divided arc
voltage in THC-------Pierce time delay----Pierce completed---CNC receives arc ok signal
from THC or Plasma then start Motion----over 90% full speed, CNC enable THC’s auto
mode----Cycle ends and arc off, Torch lift up to programmed height.

working style I tested
2 control pin
1 auto
2 thc on
1 input pin

firstly auto pin disable
enable auto pin
m205 macro (THC On enable)
wait arcok signal
auto disable

I did it manually this way but continuously

how to do it automatically

macro or gcode syntax?

Is there anyone out there is UCCNC land that can point me in the right direction?

Thank you for you input,

I suggest you load the plasma screen (if you did not already do that) there you can see the input signals better and can control the THC specific functions easier.
Then if you enable the THC and if you will turn the M3 on then the Z-axis should move up and down with the THC up and down inputs and if the arcOK signal is active.

Wiht plasma screen I've done a lot of trouble
but I'm getting an e5 error from thc control unit
thc unit datasheet ... PTHC-4.pdf
I use macro
M205 g4p500 m3
..... movement g code
M5 M206 G4P500
or M206 G4P500 M5
or the way you propose

I only have this problem. rejoice if you help me.

Alarm code: E5

Description: Collision alarm

Reason: If the proximity switch is actived before cutting or during cutting it means there’s collision, if over 0.2s will have the E5 alarm. Meanwhile send out the collision signal to CNC.

1、Checking the Micro switch and its
2、Proximity switch problem, change a
new one
3、It must press the “MENU” button
to cancel the E5 alarm After all are checked

thanks repply.
sorry error is e2

I found the solution as follows
