NO, thank you Scott,

Apparently paypal has now extended to mexico and accepted my credit card. I dont know if the transfer is immediate but i have received a payment receipt, and the amount was deducted from my credit limit, but it does not appear on my statement.
Ill email a copy of the receipt to you my friend.

Best regards
Fernando

I understand Scott...
My bank charges 30 bucks to send any amount of money to a bank outside of Mexico heheh, and I really dont trust the mexican post with an envelope with money!
I will try to register my credit card trough paypal again... if I cant then i will see if someone has a paypal account already.
my email is the same username here at machsupport but @yahoo.com

BEst Regards
Fernando

Oh wow!
Thanks Scott!

But I agree with Dave, I´ll gladly pay for the plugin.

Only one problem though since, im from mexico, last time i tried registering in paypal with my Mexican credit card, i couldnt!
do you take  credit cards directly?

BEst regards

Hi guys
Here is my entry

the bmp format is in the zip file

From what I know, there is no way to directly move the z axis with an input of button while it is running g-code.

I believe encoders send out pulses not proportional analog signals like 0 to 10v.

The linear wire encoders i believe they do not use encoders, just pots that divide a voltage, yes you could use something like that as an analog input and manipulate that value trough a brain or something like that. But a linear pot would have to be used with a "feeler" or foot that is always touching the surface of your material, If you can already tap the voltage of your plasma and translate that into a 0 to 10v signal, then the lienar pot would be redundant. You would really want to use that arc voltage as a reference since it is what really matters in the plasma process.

I have not tried the THC plugin that Brian wrote to accept an analog signal, you would have to ask him, but since in the description it says experimental-unsopported, i would believe it is not finished and would lack some features needed like arc dive and stuff like that. and since it is unsupported, i guess no changes will be made to it if requested.

Again, im no expert on this since i have never used plasma, torch height control or any type of analog signal control, im just calling it on the information I have read on this forum..

Best regards

I think there would be a couple of possibilities...

The only way mach can adjust the height of the torch while cutting is with the THC UP and THC DOWN inputs, which are digital TTL.

This said, the two options are:
1. Make a hardware interphase (beyond my capabilities) that interprets your 0-10v signal and translates it into either a torch up or torch down digital signal. you could even add PID cappabilities otherwise your control would be pretty minimal.

2. Make a brain read the 0-10v trough an analog interphase (PLC with analog inputs trough modbus) and interpret the voltage to make the torch up and down inputs work.

I could make a suggestion, but dont know it it would work or if you want to do it that way, the other options i gave you when it is all said and done will maybe cost more than a ready made THC unit from bob campbell, or sound logic, and the other provider which name escapes me right now. i think you will be amazed at the prices and features they have... besides its proven to work.

Have a chat with them and you make the decision.

Best regards

No worries BClemens, no harm done... I will merge this topic with your previous post about the VFD voltage, and lets hope someone can come up with some suggestions to see if that helps.

Best regards

Bill,
Im just pointing out that there is some etiquette, that must be followed.
I sensed some hostility in your post, and no question or comment stating your issue with the combo board.

I guess what im trying to say, is that we are here to help in what we can, if we can and it is within our capabilities and knowledge.
but we need to know what kind of trouble you are having.

Best regards
Fernando
