BF-20 CNC Conversion

[manurc]

hello budybergy
for pic, you must use the internal osc , as there is no Xtal connected

to connect the display, 1 gnd, 2 +5v, 3 contrast adj, 4 gnd, 5 RB3, 6 RB2, 11 ... 14 RB4 ..8

hope it will help you

Hello Manu
now my LCD Display Work very well but you in you Pinlayout you told me there was an failure on the pins. But now it works. Thank you

But 1 little problem i get. Why the RPM Counter counts the double real RPM ?

Maschine has 2000rpm in real you count 2x time and display 4000rpm ?
and the rpm lacks 200rpms slower as real.
Why ? Can i get the source of it ? Perhaps i can fix it?
Or i must do my own programming on this layout.

Thank you Manu
for this little helpfull thing.

Hello Buddybergy

Happy to see that you fixed the RPM gauge

How many "Frame" did you paint on the spindle ?
on mine , i just have 50 % black and 50 % natural iron to reflect the IR signal
so 1 rpm = 1 low (or high) signal

hope it can help you

Thank you Manu

but i do so 50%/50%. I have a spezial hand rpm meter which told me
the half of it and this is right,True

Your Counter programm counts 2 form black/to white and white to black .

I have try all. 2 Black part doubles the RPM. 25%black/25%white 25%bl 25&w.
or litte reflekt but no other displaying.
Or is it a problem to use a CNY70 ?

Please send me to my private address the last working .asm .hex. Perhaps it is Problem that is where a previos version of you programm ?

I have it from this site. A few pics of my LCD.

MFG

Any idea when SyilAmerica might have them and what the price will be?

EDIT: holy thread restoration batman... it is taking quite a bit of time to get the BF20 CNC (ie. Syil X5) to market...

[ataxy]

i dont think the bf20 is the syilx5

edit: from looking at the spec the say i think its the bf20 mine came at around 120kg not 70kg, there are certain thing i dont get in there description of it like

Solid concrete polymer on a steel base, precision guides? mine is cast iron all the way

I believe that Syil has not actually completed their webpages for their new mills; in many cases they just block copied the info straight across from the X2 or X3 mil, resulting in some obvious mistakes such as the ones you pointed out. I think the steel encased polymer only applies to their new X4/X4+ mill.
