Thread: The illusive Boxford 260vmc
03-08-2010 #51Thanks for that in-depth insight...
I was going to give a better explanation but it too early in the morning.
For the life of me I cant understand why we dont have a Usefull little circuit like the Trexon Tachulator from MKC Tools here on a UK site, or if there is?? why it is so difficult to find, Buy it, Fit it, Use it, Enjoy it, simplezzz. (obviosly not)
I am pretty sure (tho I've not looked at the manual) that MACH3 can provide a spindle speed display, but that wouldnt be on the machine... which would be nifty but not of any great value... finding an off the shelf panel mounted rev counter might be tricky, a quick google didnt reveal anything useful... whatever it is needs to be able to scale at 50:1. A simple PIC-based solution would be easy to implement tho...
That Texon is ugly, but easy to replicate... maybe I'll knock up a quick PIC design for it...
Well it may be ugly but its better than the ones available over here, i found loads of people asking for a circuit to do this but not many links to sites, I cant imagine there is no demand for this type of product, in fact reading the manual for the Texon they even provide a printable overley for your convienience.
There are plenty of people such as yourself who can do a little pic circuit with output to a display of some description and the maths is not too difficult for the program 50pulses=1rev for just a counter, introduce a clock and you have a tacho (not that simple i know) but it is for those people such as yourself and myself for that matter but an off the shelf solution would be better for the masses.
Yet again I am gobsmacked by the range of knowledge and skills displayed here on the Forum. For the short time I have been a member here I cannot remember a problem that has not been solved in some way or another.Tim G-C

The Following User Says Thank You to Ricardoco For This Useful Post:
Ive just moved home and that stuff formed the least important box when moving, which I suspect means it is in the most awkward place in the garage under god knows what.... HELPPPPPPPPP...
no probs rick... write the code and i'll program a PIC for you... if I havent done it first myself... lol what's your preferred flavour of PIC?
The Les Jones solution is neat, but limited... the Trexon's ability to display Surface Speed based on diameter is useful
