Snuggly's Plasma Build

@Grotius: I tried modifying the INI to reflect your suggestions and I'm still getting the "joint on limit switch error"; I realized I made a mistake, my limits/home are NC for a low level signal because of the HF plasma.

@Islander261: I was planning on tuning my machine as best as I can; I've heard pulling files through inkscape can affect the size of the file, have you had any problems with that, is there a solid solution?

Machine won't jog until I can solve this joint limit situation, I'm exploring a solution using debounce code. I will upload my hal/ini here soon. Still jumping back and forth between OS's because of this F*****ing networking issue <- taking up a lot more time than necessary

Did you check if you need pull up resistors on the inputs ?
Also do change the inputs to -in-not as suggested by Grotius.
Inkscape has everything you need for plasma, except nesting and even that can be managed by grouping things together. It does lead ins and lead outs but on all paths so that must be edited sometimes manually. It does change the dimensions when manipulating objects but very very small amounts.
The new version has a scaling problem, so do search google for inkscape wrong dimensions, there is already a fix for that. When importing dxf files, edit it and when done select everything and copy it, open a new window and paste it there, then do the path to gcode export, otherwise it will output the dimensions as pixels, so way to big.

In_not worked to sort the limit error for now. If you put in-not it throws an error. Linuxcnc is really particular!

I'll do some tests with inkscape, hopefully it'll work well because I only have the free version of sheet cam.

I need to home the machine, however because of the gantry i need to go into world/teleop mode... Which I can't get into because I need to home the machine. I've looked around in axis for a software "home", however I've not been able to locate anything. I also can't go into HIS until the machine is homed. How do I get the machine to think it's been homed so that I can actually home the machine?

I must be missing something

Are you running master branch?
Do you have home switches on both sides of the gantry?
If the answer to these two questions is yes, and you are properly configured in your INI file, then you should just be able to do a "home all"

You can check the function of your home/limit switches by using Halmeter to monitor their inputs to your control without needing to move anything. Get the switch states correct by manually operating them (finger) before you try to move the machine. If you must move anything mechanically disconnect the motor(s) before manually moving it.

In general you want to home Z axis first to top of travel (maximum Z clearance). Then home any single drive axis to a safe place and then finally home the dual drive axis. This should give you two working axis to make sure you have all the directions sorted out before going to the hard one that can really cause mechanical damage to your machine.
