Start Shaphon SH-HC31 THC

[KPB]

Is anyone using the Start Shaphon SH-HC31 THC. I have recently installed this unit upgrading from a damaged SH-HC30 unit which is now obsolete. I am having mixed success so just checking if anyone can give me some pointers on the setup.

Found this and it may help or you may try to contact the guy in the video.

Thanks for the reply. I have seen that youtube clip however, does not directly relate to my THC. The video is for the older SH-HC30 and AHD1 voltage divider. I have the SH-HC31 THC and AHD4 voltage divider.

The web site was for that THC manual

Hello everyone!
Did any one sorted out how to setup this thc?
I can't find information what settings L, u, H, d, E, b, P does? Manual is useless..

Are you having issues connecting it or setting it up?

Can you let us know what issues you are having and we can help.
I have setup a few machines in the past that used the SH-HC31 but I mostly see the XPTHC-4 or the AHA-L2
All of them need a bunch of test cuts to dial in the settings

I do not know how to set it up. Thanks.

Hey man, i have a problem with a AHa-L2, the controller is a 2012AH
The problem with the THC is that it does not correct the height, but it receives the arc voltage correctly and it is in automatic mode. Do you think it could be the speed configuration values?
What tests do you recommend?
I've been checking things for days, thank in advance!

First thing to do is go into the AHA diagnosis menu and check the limits, zero and collision signals are working

Then go into the mode menu check the settings

arc mode: sample arc voltage
arc check: check plasma arc
arc type: IHS arc strike

In the craft menu set the IHS tolerance to zero (0)

Go into the lifter menu and setup your stepper
Set the current for your stepper (: 1.5A for Nema42, 3A for Nema57)

Adjust the step and pitch till you have an accurate movement
To do this set your IHS height to a big number say 100mm
Do a zero test
Measure the height of the torch off the plate
This should be the same as the IHS height (100mm)

If this is off adjust your step and pitch till you get it right

Once you have that change the IHS to a small number, say 1.5mm
Retest and check the height
You may need to adjust the step and pitch slightly
If you still have a difference adjust with the IHS tolerance setting in the craft menu

Great post, information doesn't pertain to me but great post. Hope this gets the problem solved, please let us know.

Wow!! That should be some very useful information for our new friend from Chile. Very detailed step-by-step instructions. I hope foitzick45 gets back to let us know if your information has helped him to solve his problem. Thanks for your input.

One more thing to add to my post

It assumes the AHA is correctly connected to the CNC Controller and the plasma unit and the voltage divider is correct

To check the signals
Go into the diagnosis menu
Check the signals are correct (limits,zero,collision)
Trigger the limits,zrro and collision manually and verify they change in the menu

There is no menu for checking the arc strike and arc ok signals in this thc
So these need to be checked within your CNC Controller

Finally the arc voltage needs to be checked
Do this by cutting some lines with the THC in manual mode
It does not matter how good or bad the cuts are, for this test we dont care
With the thc in manual mode it wont alter the torch height based on the voltage

Measure the raw arc voltage on the plasma with a multi-meter
Check the display is close to what you have got o the multi-meter

If is out aby a lot its probably the AHA voltage divider not matching the plasma source

If your using raw arc on the plasma make sure the AHA divider is set to 100:1
If you are using the hypertherm voltage divider, set the hypertherm to 50:1 and the AHA divider to 2:1

I strongly recommend you use 50:1 on the hypertherm

Repeat the voltage tests and confirm your AHA is close to the measured volts

With all that said I have setup quite a few machines now that have the AHA
Its a vast improvement over the older Chinese THC's like the XPTHC-4 and SF-HC25G as it stepper controlled rather than DC motor

For those looking to purchase a THC look at the F1628S over all of these

The reason I say this is I have setup and commissioned a lot of machines with all of the above THC's.
My 2 cents is the F1628S is the best of the lot

Over all ove them the 1628S has ohmic sensing built in
This can be disabled by the CNC controller using an external signal and therefor controlled in the Gcode/Post processor

It has stepper control of the Z, so you get a precise pierce height every time (AHA does this as well)

ARC volts, Pierce delay and Height are set from knobs on the main panel.
Its the only one where the pierce height is knob on the panel, all the rest you have to go into a submenu to change
This is a pain when you swap materials

Finally the main panel is remote mounted from the main thc. The control cable us standard cat5 and I have had this as much as 50m away from the main thc. The AHA is susceptible the EMF as its an all in one box. The XPTHC-4 and SF-HC25G need a good shielded cables to the display. I have had issues with installs using cat5/6 cable

Impressed with the knowledge and following this topic out of curiosity to see if the issue was able to be resolved with all this info. Bummer so many don't post back with their results, would be helpful to others in the future.

Hi,
I also are upgrading from SH-HC30 to SH-HC31. I tried to just change the THC and use it like that, but the automatic function was not working, it seams that I need to change the voltage divider box. Do you guys know how to change the wires from the old to the new?
See attached pictures.
Thanks
