Snuggly's Plasma Build

If you already have joint.3.motor-pos.cmd going to z-pos-cmd then change line 157 in THC.hal to read

I am just emulating the entire TOMA 7i77 file as much as possible. Running into a bunch of errors but I'm knocking a bunch of them out pretty rapidly by replicating the build. Might just try modifying his build.

I'm just shotgunning these files together and chasing down errors. We'll see where it gets me. Here's what I've got so far. Hope you all had a good Thanksgiving. I'll be thankful when the machine starts making me money

Perfect, I'll start working towards that end. This isn't easy man, I appreciate all the work you've done so far! As soon as I get this machine running I can start putting time and money toward an open source table; that way newcomers won't be so overwhelmed.

SHould I be on the lookout for any problems in regards to switching the files over to ETH?

I'll keep you guys updated, hopefully we'll see some progress today!

@tommylight, How should I modify the "base thread" parport section in this file?

I'm having quite a lot of difficulty reconciling these files, would you mind helping me modify my existing files to work with this system? For posterity's sake if nothing else.

Been trying to integrate a THC into my machine files for more than a month and I've made exactly 0 progress.

You do not need a base thread running because all your step generation and io is being done by your 7I96 card. You don't need any of what you posted, do not load that file or take the section out if it is actually in another file.

pin "motion.spindle-forward" does not exist

I was able to get past this issue previously but now I can't seem to shake the error.

Look up the motion hal component in the docs. You will see that the pin name recently changed, no sleeping here.

linuxcnc.org/docs/devel/html/man/man9/motion.9.html

Read and reread and do the examples in the docs about hal configuration and use. Also study simple mill, router .ini/.hal examples until you understand them. Plasma is hard for new comers if you don't get the basics.

I uploaded a working but complex plasma configuration last week to a thread here. This is a very complex configuration for plasma. It uses a 7i76E and THCad board so will have all the .ini and .hal connections you need with simple name changes. It will not work with a Proma THC without extensive simplification.

yay... well that's not what I was hoping to hear. I appreciate that this isn't the easiest project to start with, but it shouldn't be impossible for a newcomer.

It was suggested that I try to modify TOMA, I modified the ETH version, I was told to modify the stepper version instead... I did. Now I'm supposed to go through and learn HAL from scratch so that I can make the necessary modifications?

I'd prefer, for the moment, if someone with sufficient experience could offer their help in getting my machine running. Quite honestly I feel like I'm being run around and wasting my time with linuxcnc.
