spindle curent sensing module,interfacebale with mach   Message List

Re: spindle curent sensing module,interfacebale with mach

i will definitely get there,(using emc2 for all my systems),but my funding is in
phases. I have to get things running and financially productive,even if its a
vbscript on mach,for the monthly plugins that i will have to make for weird
machines on weird coordinate systems.
i looked desperately for a way of using python to make quick scripts,found none
for emc2,but mach has low complexity road to reach the stage where you can
quickly write your scripts,for ad-hoc machines,without needing guru-hood .

so,if right now i cannot afford the learning curve of emc2 from a developers
perspective,emc2 is a natural match for the things the factories need
here,without excluding mach.
(bench presses roller feeder,sheet roller feeders for die cutting machines,mig
welding,plasma cutting,cnc routing,cnc granite machining,air less painting,glass
engraving...for the factory where i now work,as an example)

as can be seen,only 40% of the machines actually use contouring in the sense of
x,y,z.The others can be motorised by stepper or servos,via plc control,or emc2
on a single board pc)

... No, the current of an induction motor is not at all proportional to load. The current remains nearly the same, but the phase angle between the current and...

... Yes, there's a lot of code and a lot of documentation. Even in the areas that have sufficient documentation, it can be hard to find what you want (due to...
