CNC Shark to LinuxCNC Cost and Configuring LinuxCNC

Hello all, Configuring LinuxCNC has been much easier due to the creation of a wizard called pncconf. In this video, I talk through the use of this wizard to configure LinuxCNC for my hardware configuration. • Here are some notes to which I referred in the video: • Where to get linuxCNC: • o go to www.linuxcnc.org/downloads • I used this OS/LinuxCNC prebuild image (.iso) • LinuxCNC 2.8.2 Debian 10 Buster PREEMPT-RT ISO • o From the website: The Debian 10 Buster ISO uses a PREEMPT-RT patch which is close to mainstream Linux but does not, in some cases, give quite such good realtime performance as the previous RTAI kernel. It is very often more than good enough. It should probably be the first version tried even if using a parallel port. This is compatible with all Mesa and Pico interface boards. • o Write to DVD or USB Stick, boot from it and load like any other OS image • pncconf documentation: • o http://linuxcnc.org/docs/html/config/... • o choose Axis Configuration for axis and homing configuration • Pinout Information: • o On store.mesanet.com find 5i25 and go to [Specification] tab, download Manual • Page 5 has the mapping of DB25 pins (back panel of 5i25 to g540) to IO(n) in LinuxCNC • o On www.geckodrive.com select PRODUCTS at the top an navigate to the G540 page • roll down and select the User Guide tab • open the G540 Manual Rev8 and go to Page 7 for the Main Terminal Block Pinout (MTB) • o Note that the stepper motor step/direction are internally connected to the DB9 in the G540 • Note that the CHARGE PUMP connection is made internally to the G540 • Note that the ESTOP connection is internally connected to DB25 Pin 15 • o In the pncconf Wizard tool go to the Mesa Card 0, [IO Connector 3] page • o Steps/inch Calculations: • Motor is 1.8 deg/step, or 200 steps/rev • Gecko G540 is a fixed 10X micro-stepping • Leadscrew is a (measured/confirmed) 2 rev/inch • 200 x 10 x 2 = 4000 steps/inch • 0.00025 inch/step • • Limit Switch Inputs: • Signal G540 MTB IO pncconf • --------------- -------- ---- ------- • X+/- Limit/Home 1 IO13 013 • Y- Limit/Home 2 IO14 014 • Y+ Limit 3 IO15 015 • Ztop Limit/Home 4 IO16 016 • E-stop 10 IO3 003 • CHARGE PUMP N/A IO5 005 • Please adjust all above for the specific hardware you use and as always, be cautious ... this video is informational only, and I and/or this channel take no responsibility as to its efficacy and/or use.
