General Mach Discussion / Re: Input, is not output!

Hi GC,

In Config. / Gereral Config. change your IJ Mode.

Ideally you generated Gcode should include (at the beginning of the file) the G90.1 if your circles have been drawn in Absolute Mode or G91.1 if they have been drawn in Incremental Mode.

A shot in the dark but it may be an over-temperature issue with your PC. Perhaps blow it all out with an air-line - paying particular attention to the PSU and the processor heat-sink cooling fins etc.

I think you would be wise to start at say 1.2Amps then see if they get hot after 1/2 hour's running. If they are still cool to the touch then move up to the next setting etc. - at least that's what I would do.

Hi Scott,

Try it by all means but I think you will find that you need 2 power supplies to ensure reliable operation of your machine. If the hole spacings of your steppers are 47mm x 47mm then you have NEMA 23's.

Just one point - you really need to find out the maximum current rating of your unknown steppers in order that this can be set (dip switches 4,5,6) within your controller. One guy (on another forum) has just found out the hard way http://openbuilds.com/threads/electronic-nightmares.630/#post-6597

Is it normal to think you know what to do and then to be completely confused the very next moment you read something?

Hi LGF,

I think so.

This is one of the problems with life in general – the more we learn, the more we realise that there is so much more that we don’t actually know - the cycle is never ending.

Mach4 General Discussion / Re: Making MACROS turn on OUTPUTs faster by inlining your code!!

Hi Steve,

The sleep trick certainly does work, although to a certain extent it spoils the smoothness of the motion particularly when engraving small text which has many short line segments. It will be interesting to hear how Art gets on with his laser and gating the laser switch to axis step pulses. Keep up the good work my friend.

is there any people who have information about the pins of ELMO EBAF servo drives; such as +-10 v and servo enable?
i want to rebuild old CNC MACHINE to mach3 and all drives are analog from ELMO EBAF
please share your information.

Hi Victor,

This pdf attachment may possibly be of assistance to you.

Hi LGF,

Welcome.

You are not wrong, a homebuilt CNC machine is never truly 'finished' I completed mine (so I thought) 10 years ago and I am still adding stuff.

Hi Steve,

The LinuxCNC M62P1 / M63P1 appear to operate in exactly the same way as the Mach3 M11P1 / M10P1 commands. Certainly for laser use it would be nice to have this command set within Mach4
