Zelrp + Linuxcnc 2.7.12 + THC 150

On the original thread and on the howto file there is a mention on setting up the Proma to work with that config, but here it is again if i remember correctly:
on the Proma THC press and hold the two buttons, it should show Hys, delta V, and some other stuff, namely what voltage should be considered as ARC OK. Set the first two parameters ( hys and delta v ) to the minimum, that way it will react much faster.
Do keep in mind that it uses relays on the outputs, so it will not be fast enough to cut 0.8mm corrugated plates, but it will be fast enough for almost anything else.

Hello again!

I have last two questions. First: how can I change default step size and gap? And second what can I do to have sharper corners?

Open and edit the "thc_vcp.xml" file and change the "initval" to what you need.

<spinbox>
<halpin>"Spin-THCStepSize"</halpin>
<min_>0.01</min_>
<max_>1</max_>
<initval>0.02</initval> <<<<<===== change this value for step size
<width>"6"</width>
<resolution>.01</resolution>
<format>"5.4f"</format>
<justify>RIGHT</justify>
</spinbox>

<spinbox>
<halpin>"Spin-PierceGap"</halpin>
<min_>0.5</min_>
<max_>10</max_>
<initval>2</initval> <<<<<<<======== change this for the initial gap
<width>"6"</width>
<resolution>.1</resolution>
<format>"5.2f"</format>
<justify>RIGHT</justify>
</spinbox>

And now...

That is niceeeeeeeeeeeee.
The result makes up for the trouble, for sure.
