Thanks Wilabee,
Your first line said it all for me!!!.
With just wanting to try out the TEXT facility I had completely forgotten to load a file.

Thanks for the memory jog.
Now to try again.

LazyCam (Beta) / LC v2.081 Text

« on: July 09, 2007, 06:08:57 PM »

I have tried using the TEXT facility in the latest LC without success; is it fully implememted?
I entered text, and was instructed to drag out a box and the text would appear in the box.

I could find no way of drawing a box or dragging the text..

Anyone done this yet.

Impressive list of fonts though.

Jim,
Have a look at www.arceurotrade.co.uk.
I have heard there motors are very good and I am sure they will discuss your requirements with you.

Homecockpitbuilder,
Did you manage to packet your text.
I have been struggling to do this with the Trinity font but no success yet.

I dont really want to slow the motor down and I am told it is quite happy running at 4200. This is apparently the normal condition for the Minimill, 130 volts and 4200revs max.
Of course the control system is completely different from normal apart from the Lenze534 speed controller which I managed to obtain second hand..
There are some adjustmants on the Lenze which I think I should check out as well, they may be for just this purpose.

I should be able to check the spindle speed using a tacho later in the week so will see the true speed.

Yes I altered the pulley setting to 0 - 5000.
I have also tried the 'Timing' pins in stead of the 'Index' pin.
For this I uncovered the slots (4) on the sensor disk.
I obtained another straight line graph with I think better control..

Timing  gave   revs=1.35(S)- 650 compared with:-
Index            revs=3.0(S)-1000

On the general config window are 2 options that may be related to spindle control (on the right hand side).
Do you know the function of these?

minPWM setting of 0 makes no difference to the spindle revs/control.
I will check out the digispeed manual re your suggestion.

Vmax,
Yes I am using PWM and M3 M4 still working as they should.

PWMbase is 50 but I have the minPWM set at 10% - I will try that at 0% tomorrow.

Good idea including Peter I will do that.

thanks,

Vmax,
Some success at last

Removed Mach3 via control panel.
Downloaded latest version - 2.0.080 and installed it.
It had retained my .xml file so checked settings OK.
Set pulley #1  100 and 2000, left ratio?? at 1.
No spindle calibration carried out.
Config pins set for index and one untaped slot on spindle disk.

I'll give you the results of using MDI unput.

   S      RPM (indicated)
  300    0
  400    187
  500    503
  600   807
 700    1112
  800   1421
  900   1723
  1000   2026
  1100   2336
  1200   2635
  1300   2935
  1400   3241
  1500   3542
  1600   3837
  1700   4150
  1800   4454
  1900   4730
  2000   5000 +/_10
  400     188

Apart from a dip at s400 these readings lie on a straight line.
Obviously the spindle calibration should bring the slope of the graph to 45 deg.

Thoughts on this success??

Malcolm
