General Mach Discussion / Re: Z-Axis Repeatability: Small Changes

« on: October 30, 2015, 02:34:29 AM »

Hi Richard V,

Try halving the Velocity and acceleration you have set for your Z axis in Motor Tuning (save the changes).

If this cures the problem then you need to find the optimum reliable settings for this axis.
If it doesn't cure the problem then I suggest you thoroughly check the mechanicals - such things as loose set screw in couplings, binding or tightness of slides or screw etc.etc.

Mach4 General Discussion / Re: Pokeys 57E Issues mach4

Beautiful looking plane Paul. (Mine are all small enough to fit into the estate).

Afraid I cannot suggest anything that may cure the runaway situation - it sounds downright dangerous to me.
I gave up on Mach4 almost a year ago now. I found that I was spending more time looking at the screen and typing than I was actually running the program.
Sadly it seems that if you enjoy LUA programming, macro and problem solving in general then Mach4 is absolutely excellent but if you just want to make stuff with a CNC machine then Mach3 is still years ahead.

How to get the real license?

As Peter has said, buy one from him. Alternately visit the official site http://www.machsupport.com/licensing/

Hi Paul,

Just an observation regarding your last post but you should really get into the habit of getting your control software (Mach3/4) up and running before you switch on or enable your CNC machine. Literally anything could happen (characters sent, outputs switched etc.) during the computer's software start-up sequence and an out-of-control machine does not bear thinking about the possible consequences to life and limb.

(Old hands at flying RC will know what I am talking about regarding switch-on order).

It would be so much easier setting up a Mach workshop in the Northwest (UK) as it would take minutes to get the basic setup sorted.

Sounds like you are talking yourself into a little project there Rob.

Mach3 under Vista / Re: Windows 8 and Mach 3

« on: October 25, 2015, 11:35:45 AM »

also, as windows 10 comes as free upgrade, is this compatable with the mach3software.
many thanks and regards,

Mach3 will run just fine under Windows 10 but you cannot use the parallel port it has to be Ethernet (preferable) or USB, external motion controller.

It could be caused by electrical noise or it could be caused by mechanical vibration affecting mechanical switches (home, limit, estop, etc.)

Try increasing the Debounce Interval (Config. / General Config.) to 2000 or so and see if this resolves the problem. If it does then, as soon as time permits, you need to investigate the root cause (electrical noise, vibration etc.).

I am pleased you have got it sorted.

Please remember that increasing the Debounce is a fix a bit like a sticky plaster you really should find the root cause and cure that.

Tangent Corner / It just stopped working !

« on: October 21, 2015, 07:50:32 AM »

 Nothing to do with CNC but my Yamaha MagicStomp just stopped working, the display backlight would illuminate but that was it and as this pedal is no longer in production it was either repair it or bin it. Perhaps a compelling argument for a repair is that these pedals are now selling second-hand (or should I say second-foot) for around double the price they cost when they were new !

 It transpires that in the start-up sequence the control microprocessor writes to the display and then waits for a reply. Testing the display in this manner is just fine for Medical & Aeronautical equipment but hardly necessary for an effects pedal - after all, if there is a problem with the display the software just hangs forever - still, that’s the way it is.

 The actual display is a 16 char 2 line - cheap and readily available – tricky to replace (soldering skills required) but not rocket science. I chose to replace the original yellow / black with a high contrast blue / white display and for an hour or so quite delicate work I have an old friend back.
