HP105 THC problems

Post by 8SecondDave » Fri Oct 08, 2021 7:59 pm

Does anyone have any experience with a HP105 height controller? I have a table with that and a Starfire cnc controller but the instructions for both are translated from Chinese and make little sense.

I'm having trouble getting the right settings for arc voltage and understanding the "IHS time" setting.

From what I can understand the IHS time is actually a setting for the peirce hight as there is already a separate setting for peirce time and when I set higher IHS time it gives a higher peirce height but there seems to be no way of working out what time to set to give the correct peirce height other than guessing and a lot of trial and error. To make matters worse, if I try to pierce and hit pause to measure the peirce height the torch lifts as soon as I pause. Is anyone able to explain this better to me about how it works and how to work out the right setting? Or perhaps someone wouldn't mind sharing a list of their own settings that work?

I have a similar problem with the arc voltage, if I pause a cut to try to measure the cut height the torch rises as soon as I press pause. The only way I have been able to get close to the correct cut height is watching it cut and estimating whether it is cutting at the right height or needs adjusting. Does anyone have a better solution please?

Not familiar with your equipment, it seems odd that IHS (initial height sensing) would have a Time associated with it and not a distance. What sort of values are you experimenting with? You have the right idea pausing to check the pierce and cut heights but all I can suggest is go through the Menu and see if you can determine if there is a feature you can turn off so the torch doesn't rise on pause. Trial, error and documenting your results is likely the best you can do but hopefully someone else here has sorted this out already. Curious to hear what you find out, good luck :Like

Thank you, mostly setting between 0.2 and 0.5 seconds, this seems to vary the pierce height considerably. I have also noticed that the torch is stationary for the pierce delay that I set, but then starts cutting and doesnt drop to cutting height for a second or 2 afterwards, this seems to be regardless of any settings I input. If anyone has any suggestions or soutions to this too I would be very grateful

Just out of curiosity - does your controller have the ability to disable thc (monitoring arc voltage to maintain cut height) and manually set the cut height and pierce height? If so, and if you are just trying to get this table up and running, then that might be a good place to start.
