PlasmaC questions new setup

I take it will be all open source

Well when I look at what you guys have done to Path Pilot whats the point in not going that way?
There are many fabricators who can build a table and want a prebuilt controller. Sounds like you know someone like that!
I've seen a few eyes glaze over when I open the Spaceship control cabinet!

I will say though that what we have learnt about stepper motor design is cutting edge and has rewritten everything that I thought I knew on the subject through my seat of the pants spaceship build. So we are talking about adding a lot more value than a prebuilt controller. Geeze the wiring gave me the Sh!ts! And its still doing my head in as I work through how everything needs to go together!

OK the Hypertherm 45xp is on the way.

I have used the online calculator jscalc.io/calc/NTr5QDX6WgMThBVb

It produce these:- Started with this on the back of the THC-10 0V = 116.4 10V + 965.3

This is the result Scale 0.01130875 and offset 3637.5000 Does this look correct as I seem to have used a 9V battery last time

Yes it does, for a 30:1 divider.

Thanks Tom. I left that bit out to check if you was really checking You passed:woohoo:

One more question

will I need a relay with the 7i96 for the arc transfer pins 12,14 on the cnc port as they are ssr on the 7i96 TB-3 pins 13,14

You should be fine with the internal relays. the outputs are 36 volt 2 amps, way more than what would be use.d

From the manual:-

Start (start plasma)
Input
Normally open. ...15 VDC open circuit voltage at START terminals. Requires dry contact closure to activate.

Transfer (start machine motion)
Output
Normally open. Dry contact closure when the arc transfers. 120 VAC / 1 A maximum at the machine interface relay.

Voltage divider
Output
Divided arc signal of 20:1, 21.1:1, 30:1, 40:1, 50:1 ... (provides a maximum of 16 V)
