'''Cnc torch table notes'''

==Height control==

===Specs for stable plasma cut===
Three components to plasma height control:

1. '''IHS (initial height sensing)'''- this is the touch off height or pierce height for the torch (pierce at 150-200% of the cut height). Capacitive sensors would work best for thin material since a mechanical switch could deflect the material giving a false reading. Two chips I have used for touch screen buttons are:

freescale: http://www.freescale.com/files/sensors/doc/data_sheet/MPR121.pdf

and

Qprox: http://media.digikey.com/pdf/Data%20Sheets/Quantum%20PDFs/Qt160_07.pdf

These provide baseline sampling compensation so they act like a switch more than a sensor but for the initial height sensing I think they would work well.

2. '''Cutting height'''- is determined by the plasma torches cutting voltage, since the plasma torch uses constant current a 1% change in voltage (100 to 101 volts) is equal to several thousands (typically .015 or more) of arc gap change. This voltage can be read directly from the plasma torch, most torches have a voltage output (example):

PowerPlasma 60S
OCV 200V
working voltage 88-100
has outputs for 1/16 or 1/50 which gives a output of about 4V

This can be measured by a a/d on a microcontrol but needs to be isolated first. The sample rate should allow a A/D reading every .5 second.

The Atmega1280/328 sample rate for a A/D is 14 clock cycles the A/D has a internal clock that should be set to the lowest sample rate of 50KHZ this will help with noise and give a more accurate reading, also as many IO ports as possible should be in High Z to ensure better reading. It seems like a half second latency is the cutoff for sensing and correcting at 25KHZ 14 clocks would give 1785 samples, to deal with noise probably 50 samples should be averaged, most commercial systems are claiming a 6Khz sample rate. 10 bit resolution gives a 1023/AVcc if a 5v system is used that gives 4.88mV resolution.

1023/5AVcc = 4.88mV resolution

100v/50 = 2V output from plasma torch

2V/4.88mv resolution gives 0-409 range or .244V resolution from the plasma torch or theoretically 3 mill this should be fine.

3.'''Event monitoring'''- needed to monitor crash/limit switches and also torch control variables, if the torch slows down as in a curve the voltage will rise and cause a erroneous lower of the torch. These conditions need to be addressed in software.

Possible systems

===Software integration grbl===
''Use with grbl'' The G code is parsed from serial input checked for exclusivity in command structure then parsed into a block which is stored in a ring buffer the ring buffer is read out one command at a time utilizing the fixed timer1 interrupt (TIMER1_COMPA_vect) to run the pulse event and timer2 compare to clear the stepper port I/O. They use different motion envelopes to interpolate speed/distance with each command.

''Integrating a THC''- To integrate the torch height controller four components would need to be integrated (limit switch, z axis motor control, two height/ A/D sensors and G-code parsing for a M command). Since grbl already controls the z axis in software a new block could be designed for each stage of torch setup, touch off, piercing, cut ect. The problem will come from integrating the sensors into the program flow grbl is right now a event driven machine either from a serial event or then a timing event to control the the rest of the control structure.

Since the THC is only a specific process for plasma and oxy-fuel cutting I recommend developing a second board to run the sampling and motion control for the z axis while using a plasma cutter this will avoid the problems of:

Latency caused by a conflict with the A/D sample rate and the stepper pulse train. This will decouple the sample rate from the timed execution cycle of grbl.

I/O for future iterations if height and angle are desired as in some commercial applications along with limit switches and sensors the available I/O might get in short supply depending on which Atmel chip is used.

To keep grbl a lightweight targeted code base development of code to run on a separate processor would in my opinion keep the code base cleaner, instead of writing a bunch of exceptions for new timing models.

===Use with oxy torch===
Most height control systems for oxy torches use a capacitive sensor with a ring:

http://www.agelkom.com.tr/prod02.htm

http://www.youtube.com/watch?v=b0TpmfcNzeU

there is not the same issue of noise so I think it would be feasible to make a capacitive sensor based height controller that could be used in both cases. With the plasma torch the capacitive sensor is used ONLY for touch off then it switches to the voltage sensing for the cutting. The oxy-fuel would use the capacitive sensing throughout the cut at a high sample rate.

==Mechanical==
Direct drive to threaded rod, Thread pitch/step pitch/minimum xy step needs to be computed in regards to compute sample rate for height sensor. Needs one stepper motor for z could use another for angle rotation. Most systems just use some extruded track material and a antibacklash nut to control height. Make sure it can accommodate Oxy and plasma torch head.

I recommend a separate processor for height control.

The OSE Quick Attach will be used to implement a wide range of attachments for the OSE skid steer. The design considerations were:

1. Use existing OSE parts (4"x4" box tube, 1/2" plate, 1" bolts, etc).

2. Minimize welds, main attachment method bolting.

3. Modular so the spacing can be changed according to attachment.

4. Conforms to SAE-J2513 standard.

The drawing shows a reference for multiple designs, the DXF file has the dimensional layout (select layers accordingly, when they are all on it is cluttered).

For the next step it would be good to talk with whomever will fabricate it to lock in the most efficient build based on available parts, especially for the catch mechanism.

==V2==
Added in more dimensional work for attachment spacing to skid steer, finished latching mechanism.

Latch mech:
The latching mechanism KISSes by utilizing a 5/8" threaded rod that attaches to a 1/2" plate with weld nuts. The plate moves the latch rod to connect and disconnect, this gets rid of any spring or lever which could jam or release during use.

All parts are standard McMaster.

Added in more dimensional work for attachment spacing to skid steer, finished latching mechanism.

Latch mech:
The latching mechanism KISSes by utilizes a 5/8" threaded rod that attaches to a 1/2" plate with weld nuts. The plate moves the latch rod to connect and disconnect, this gets rid of any spring or lever which could jam or release during use.

All parts are standard McMaster.

Bobcat Standard Quick Attach

IEF RD: /* V2 */

=Background=
The OSE Quick Attach will be used to implement a wide range of attachments for the OSE skid steer. The design considerations were:

1.Use existing OSE parts (4"x4" box tube, 1/2" plate, 1" bolts, etc).

2.Minimize welds main attachment method bolting.

3.Modular so the spacing can be changed according to attachment.

4.Conforms to SAE-J2513 standard.

SAE standard: [[File:sae_j2513.pdf]]

See [[LifeTrac_Bobcat_Standard]] and [[Quick_Attach_Plate_Standard]] for background on geometry and discussion of ASTM specification of the geometry.

=Product=
==V1==
hashed out different design options, made original DXF file.

The drawing shows a reference for multiple designs, the DXF file has the dimensional layout (select layers accordingly, when they are all on it is cluttered).

For the next step it would be good to talk with whomever will fabricate it to lock in the most efficient build based on available parts, especially for the catch mechanism.

Hey Guys I tried again to log into the Wiki but no luck. So here is what I cam up with for the quick attach. It is enough to set a cut list and build a prototype.

Attached is a drawing with the ideas I hashed out to give a reference, a Read me file for any notes and the DXF file with the layout (select layers accordingly, when they are all on it is cluttered).

For the next step it would be good to talk with whomever will fabricate it to lock in the most efficient build based on available parts, especially for the catch mechanism.
