First off while I will call this a feature request, it is also something I would put at the bottom of the list as there are so many other areas that better deserve attention. I do put this out there because it might be really simple to do. I don't understand many parts of LinuxCNC “under the hood” so I'm not sure what I am really asking for. What I was envisioning was some sort of LCNC app or perhaps maybe mode would be a better term. Goal – to be able to hook into an existing working CNC machine and monitor encoder counts, spindle functions etc. so as to be able to record and analyze the machine performance and characteristics so that a LCNC integrator has a known good working baseline so that he can duplicate the original OEM manufactures performance.
By providing a series of simple test programs that would be run by the CNC and the same program provided to LCNC so it can follow along and decipher the moves and actions. Such as: G0 X0 Y0 X15 Y5 X0 Y0 This would track accell and type ( trapezoid or S-curve ), peak velocity, and rapid type ( linear or max velocity ) and allow capture and calculation of encoder resolution or steps per unit. Another area is spindle drive commands for G84 (tapping cycle) does the machine feed the tool down to Z then... a) via contactor open the FWD contact then close the RVD contact. b) via contactor open the FWD contact then apply mechanical brake, dwell, release brake and close the RVD contact. c) Via VFD switch from forward to reverse instantly. d) Via VFD stop FWD, apply breaking resistor before engaging RVD. e) Other For lathes it can also measure spindle acceleration for CSS. I know that hooking up to the machine would likely require the same or nearly so the electronics needed to retrofit to LCNC, and in many cases maybe quite a bit more. ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
