General Mach Discussion / Re: problems with machining holes and Z axis

« on: October 09, 2017, 02:10:12 PM »

Hi,
I still think you are gaining or losing steps and not just restricted to the Z axis.

The acceleration setting in motor tuning is very important, if its set too high it will loose steps. One recommendation is to set it
at no more than 10% of the velocity setting. The general principle is start slow, very slow and then increase the settings until it
starts misbehaving and then back off a bit.

PoKeys / Re: Pokeys 57U - Spindle Speed Control

« on: October 09, 2017, 01:58:30 PM »

Hi Chaz,
somewhere in the manual there will be a circuit diagram of the pin.

PoKeys seem to classify them as DO5, DIO33, OCOC etc. Any of them could be used but need to find out which one is used on this pin.

Hi,
well the PC and parallel port certainly look fine.

What breakout board are you using? Can you post a pic and maybe the manual?

General Mach Discussion / Re: Toolpath Display

Hi,
sounds like the toolpath is being drawn in the wrong units. Is your Gcode drafted in inches or mm?

Hi,
set up the buttons and a folder and the rest I can help with.

Hi,
I can't download a manual so I can't tell what pin 17 is. Can you either post the manual or tell me what type of output it is.

Hi,
if its an open collector type output then yes you could use the 10V from the VFD.

Can you identify the type of output you're using? PoKeys seem to have several types of output, not all will do as you want simply.
Can you post the circuit diagram associated with the pin?

General Mach Discussion / Re: Spindle RPM and Threading Problem

« on: October 09, 2017, 01:38:44 AM »

Hi saschko,

shouldn't it synchonise the axes feed depending on the RPM that it counts from the Spindle Index input.

yes it should, but is it?
Isn't that the whole point of the post?

You need some way of confirming that Mach is ACTUALLY reading the spindle index. While it needs it to calculate its current speed it is in fact more
important than that, it synchronises the start of the thread when doing multiple cuts.

Do you have or can you borrow an oscilloscope? The picture showed what I called a proximity sensor. They are pretty lethargic, it may not be fast
enuf to send individual pulses. Do you have any specs for the sensor? I have seen some that are good to several hundred Hz, easily good enuf but others
that can only manage 10 Hz, and they wouldn't.

Hi marchmade,
how did you get on? Has the ESS played ball and did the Warp9 instructions help?

VB and the development of wizards / Re: Doubts about M6 macro

« on: October 09, 2017, 12:15:37 AM »

Hi,
can't quite see the purpose of the signal unless it actually reflects whether a tool is in place or not. Additionally if the signal is not valid until
the macro has been run once and yet you could crash your machine if you assume no tool is in place when in fact there is.

I reminds me of a cartoon character who was happily sawing a branch that he was sitting on....but he was outward of the cut!

I take it that your spindle is not equipped with a 'tool in place' switch? How about your carousel? If there were a proximity switch on each of the
tool recepticals and one was missing, it must be in the spindle. If all proximity switches are active then all the toolholders are in the carousel
ergo there can't be one in the spindle.
