Hi John,

I am pleased you have got it sorted - you are certainly progressing up the learning curve at speed now.

Hi John,

Sounds like you have your X axis configured incorrectly.
In Config / Ports and Pins / Motor Outputs - change the tick for a cross (or visa versa) in the 'Dir LowActive' box for the 'X Axis' then click 'Apply'.

Very nice Tweakie, can`t wait till you finish. I am sure it will be awsome, I would love to make one as well.

Hi Astroguy,

Thank you.

I keep making minor alterations to the basic design (from experience gained and others suggestions) but I am nearly there.
I have almost compiled a complete set of drawings and GCode files but this seems to be taking longer than it took to make the original parts.

Hi Russ,

Yes, fortunately for me, the shifts occurred between the wording and I was able to locate the same datum point at each shift.

Not sure if I can get a picture of the finished product, my part is just the VCarving - all the finishing work will now be done manually by an experienced woodworker. (I trust the final customer has plenty of cash because I can see this becoming one really expensive piece of bling).

A little more progress - This is the over-travel limit switch, well 3 switches actually but they are connected in parallel and operate on the 'first home' principle.

The total thickness, including the PCB, is 2mm and this assembly fits beneath the the contact plate (in the base of the probe) and will activate a limit input if the G31 probing routine failed.

The probe will continue to use the 3 wire connection to the machine and additional circuitry has now been fitted, at the breakout board end, to detect probe circuit continuity. This effectively signals a 'Probe Already Grounded' condition to the probing routine if either the positive or GND connecting wires are disconnected or if the probe is not actually connected to the machine. This added 'fail safe' feature was considered necessary because I am signalling the over-travel limit through the two supply wires.

Hopefully, I have now covered every eventuality but life always seems to punish the complacent and so 'time will tell'.

Well, I finally got around to VCarving this boat name into a piece of Teak.

Because the overall length is greater than my machine table it had to be completed in 3 stages but this is not as difficult to do as I had first thought, having previously practised on a piece of MDF.

Now the hard work begins - It has to be profile cut to a curved shape and the edges rebated, varnished and the lettering gold finished.

Hi Doug,

The tb6560 controller works best with a 5Volt TTL signal, if your parallel port is only outputting a 3.3Volt TTL signal then this could be the cause of your problem. Check your X axis Direction pin with a voltmeter - it should switch between 0V and 5V (approx.) depending on the direction of motion.

Hi Rune,

I am pleased that you have found the solution.

Hi Rune,

The GCode is fine and this is not really a Mach3 issue because the problem appears to be with your use of Sketchup. You have no material size set so there is nothing to make.

My best suggestion is that you check out the Sketchup tutorials in order to find out how to select the area of the drawing you wish to create the GCode for. The Phlatforum will have all the information you need but you will have to search for it.

Hope this helps.

Hi Rune,

There should be no problem using the Phlatscript GCode with Mach3.
If you post your code I will take a look to see why you are having a problem.
