« on: November 22, 2011, 04:36:56 AM »
Ian,

With version R3.043.022 and using G90 G31 any deceleration settings in motor tuning are totally ignored when the Z Axis comes to a halt.
I am still testing but so far I can find no evidence that the value retrieved from Get Var (2002) is over-written by any subsequent contact, it is just the first trip point that is recorded.

Hi John,

As Rich says the driver test installs the Mach drivers but if the driver test does not run then the drivers for Mach are not installed. It's a Catch22 situation.

The reason that the driver test does not run is almost certainly due to your PC. I think you should perhaps try another PC.
(Others, in the past, have reported taking the driver test.exe program to their computer shop and said " I want to buy a cheap PC that will run this")

One thing I did notice on the parallel cable was that on pins 15 and 16, there was also 5.05v, even when there shouldn't be??

That would concern me - it should cleanly switch between Hi and Lo in order to perform the correct logic function.
Perhaps you need to check that your LPT2 is configured and working properly as it sounds that you may have a problem here.

HOWEVER - if the probe contacts are re-made and then re-broken during that decceleration phase, Mach will RE-WRITE that point as the point of contact.

HUM I have never seen it double write the trip point here. Once the initial trip takes place the G31 is no longer actively waiting for a trip it is already into the record and stop sequence of the code. At least that is how Art explained it a long time ago.

Perhaps this point needs to be investigated, at least as it applies to the latest lockdown version - does it re-write or not ??

Thanks Ian - this is something I had never considered (or even thought about happening).

« on: November 21, 2011, 11:34:12 AM »
Hi Tony,

I am sure it can be done but it is really a job for an electronics engineer. The necessary signals are available from the PC graphics chip but the signal levels need to be checked prior to connection to the screen, get it wrong and damage to the screen or PC could occur.
In my opinion, in this instance, the risk is too high for 'trial and error' type electronics.

Can this bee sett in the softwhere- "high or low"?

I suppose you could use a 'pull up resistor' for the circuit to be 'active high' and a 'pull down' resistor for the circuit to be 'active low' then configure Mach accordingly.


Quote
Another thing I was wondering about,- how accurate is this Probe? Surly there have to bee some play/movement of the ProbeTip before the circut is broken and a signal given. Can this be compensated for by the software?

If it is constructed properly and the spring yields before anything bends then it would be extremely difficult to measure any play/movement in the system. Consider that the tip is essentially resting in the 'V' between 6 points of contact, it will either be making contact or it will not, there is no delay or contact bounce as you may get with, for example, a conventional switch.
When probing there is 'overun' between the contact point and the axis coming to rest but the stored position is the actual point of contact not the final axis position so compensation is automatic really.

Hope this helps.

Yes - between pin 14 and GND (which is pins 18 to 25) should do it.
The cable length will make no difference for this test.

Tweakie.

nb. While you are testing check the cable to make sure you have the right type with Pin 1 connected to Pin 1, Pin 2 to Pin 2, etc

Hi Keith,

My mistake, I was thinking in terms of an axis - use whatever control you use to Enable / Disable the pin you are measuring.

(Thanks for the complements - some of the stuff on the site is quite old now and I keep thinking I must update a lot of it  :-\ )
