Building a chain driven Plasma table.

Thanks.
I just used conversational in qtplasmac.
I tried to increase cutting speed.
But it always cuts the same slow speed.

I downloaded sheetcam unfortunately it already asks for a
License key.

Is there any free software to generate G code for plasma?

I have actually seen this issue with LinuxCNC, but it may only have to do
with displayed numbers. I think many displayed floats are single precision.

Home / Soft Limits - Not homing before moving axis(s)

Category: General LinuxCNC Questions

the home offset for x,y is because thats where the vise is. its not zero, its within the coordinate system limits. it homes to 0,0,0, then offsets within the coordinate system where i tell it to. does that make sense?

If you just need GPIO all 17 P1 I/O pins are available as GPIO
with the default firmware.

The GPIO numbers vs P1 pins are listed in the .pin file:

IO Connections for P1 -> 7I97_2
Pin#                          I/O   Pri. func    Sec. func        Chan     Sec. Pin func   Sec. Pin Dir

P1-01/DB25-01          34   IOPort       None           
P1-02/DB25-14          35   IOPort       None           
P1-03/DB25-02          36   IOPort       None           
P1-04/DB25-15          37   IOPort       None           
P1-05/DB25-03          38   IOPort       None           
P1-06/DB25-16          39   IOPort       None           
P1-07/DB25-04          40   IOPort       None           
P1-08/DB25-17          41   IOPort       None           
P1-09/DB25-05          42   IOPort       None           
P1-11/DB25-06          43   IOPort       None           
P1-13/DB25-07          44   IOPort       None           
P1-15/DB25-08          45   IOPort       None           
P1-17/DB25-09          46   IOPort       None           
P1-19/DB25-10          47   IOPort       None           
P1-21/DB25-11          48   IOPort       None           
P1-23/DB25-12          49   IOPort       None           
P1-25/DB25-13          50   IOPort       None       

Each GPIO pin (GPIO 50 = DB25-13 shown here)
Will have three hal pins available for connections
in your hal file:

hm2_7i97.0.gpio.050.in
hm2_7i97.0.gpio.050.in_not
hm2_7i97.0.gpio.050.out

and three parameters that need to be set
appropriately if the GPIO pin is an outrput

hm2_7i97.0.gpio.050.is_output
hm2_7i97.0.gpio.050.invert_output
hm2_7i97.0.gpio.050.is_opendrain

All GPIO pins startup as inputs so the "is_output"
parameter must be set "true" for any GPIO pin you wish
to use as an output

Home / Soft Limits - Not homing before moving axis(s)

Category: General LinuxCNC Questions

the limit switches are set to home+limit currently. machine homes to the switches, then brings each axis in a little; .125" for Z, and about half way for x & y.

OK for Z, wrong for XY, why would you have machine 0 at the middle of the table???
Always (almost) the machine 0 is at near left side.

Home / Soft Limits - Not homing before moving axis(s)

Category: General LinuxCNC Questions

im not looking to crash it lol
i just got use to a certain way of a cnc program working (usually).

the limit switches are set to home+limit currently. machine homes to the switches, then brings each axis in a little; .125" for Z, and about half way for x & y.
once homed, it will allow me to travel to the extents of max set in the gui away from the switch (hard stop) and then basically stops at the switch in the opposite direction (also hard stop).

is this the correct way to have it setup?

Home / Soft Limits - Not homing before moving axis(s)

Category: General LinuxCNC Questions

You can set LinuxCNC however you like with a bit of effort, but i would strongly advise to stop comparing it to Mach3.
There are plenty of reasons as to why LinuxCNC does things as it does, and those are based on running multi ton machines, not some hobby Nema17 machine.
If you want to use soft limits, omit the limit inputs in config, but you will crash the machine for sure, sooner or later.
You can have limit switches active and use "immediate homing" and that will work as soft limits until it actually triggers a limit switch.
My advice: Home the machine.

No drag shield.
Looks like to slow and a bit to high.
You will have to do a lot of test cuts to find out what works for you, so do straight 100mm cuts first while changing cut voltage (that is torch height) and feed rate (can be adjusted on screen while cutting), but first and foremost, use new consumables and make sure the air pressure is as specified in the manual while the torch air is on.
After you get clean cuts with little dross on straight lines, do some small squares and some small rounds, about 50 of each. If that all works OK without issues, cut some bigger logo or whatever you like.

Home / Soft Limits - Not homing before moving axis(s)

Category: General LinuxCNC Questions

So im trying to understand how to fix this operation. im use to mach3's behavior of soft limits. mach3 keeps the machine coordinates and my part offset, so if i shut down and fire it right back up, i can move the the extents of the soft limits, it slows the stepper shortly before reaching the soft limit and slows it down in speed slower until it hits the limit.

Currently in LCNC, unless i home all first, there is no soft limit, only the hard limit switch i have one side. ignore limits is not selected in the gmoccapy gui. programmed hard limits work on both sides after homing.

I would like it to atleast use the soft limits without having to home first; if i can get the steppers to slow as the limit is reached that would be a bonus. thanks in advance!

So I made my first cuts. 
Made some 30mm holes in some square tubing. See photo. Is this what you can get from plasma or can plasma cutting do a better job? 

I use a Hyperterm Xp 45 powermax. 
With a hand torch and a drag shield will quality improve if I use a shield that is made for a machine torch?
