Hi, To everyone involved, thx for LinuxCNC and specifically the BBB port!!!
I have been off and on lurkin on the fringes of EMC & LinuxCNC for years. Once upon a time I had an order for a shoptask machine, but canceled after 7 months of no delivery. I still keep an old Sony Viao laptop running at a blistering 150Mhz loaded with EMC. It has a paralell port and I patched the kernel with RT linux back when that was the way to go. I got stepper motors, assembled drivers from kits, mounted them all in a metal box with a fan etc. All dressed up and nowhere to go. I figure it is time to uncloak and try to contribute since I have hoarded most(all new) parts for my latest project. I have almost everything needed except ball screws (or belts) for a cubic meter sized 3D printer. I have an Airwolf3D (reprap type) printer now. I seriously doubt I'll end up with a meter for each axis though. Now I'll attempt to contribute. >Re: Using an old Anilam control panel with LCNC? (Gregg Eshelman) PYLE makes a 9" monitor with VGA input for headrest usage, amazon for about $150 It's only 480x234 though. Perhaps you can mount a larger LCD just in fromt of the bezel hole? A 16" with VGA input can be had for about $50 Not as neat but way better resolution to choose from if you are willing to consider that route. >Re: Thermocouple to LinuxCNC (Mark Wendt) For interface you might consider an MSP430F2012 (12 bit A/D) or a ~F2013 (16 bit A/D) A whole 1.8-3.3V MCU with 8 channela/d already mounted on a tiny PCB. The 2012's are about $5 each($16 for3). (you will need a launchpad or similar to program it ($10-25) ) The launchpad has enough to get you going if you don't insist on SMD for size and low weight. They can communicate via I2C SPI 1wire UART etc. Mount that puppy on the print head and use cheapo wire when(not if) it needs replaced due to flex. If you re-considered a thermistor. There are >300C thermistors. You don't need to use the A/D method (with a thermistor), You can use an R/C circuit, charge it up and time how long it takes to read a zero on some port bit or toggle a comparator. The same port pin can charge and then read the circuit. This is how many touch sensors work but the variable is a capacitor instead of a thermistor/resistor. This is the plan for my BBB LinuxCNC 3D printer, a TI MCU companion for my TI SoC. :) I am also planing fornylon capability. AVR has similar MCU's available if that is your flavor of choice. I don't know of any AVR devices that come on tiny PCB's ready to program though. It's similar in complexity to just using a standalone a/d. There are many sample programs ready to adapt. Food for thought! Thx again all for LinuxCNC ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
