In some ways the waste can be more interesting than the part.

Best price for a (second user) scanning head I have seen so far (with ZnSe lens) is $2,800 + import duty, tax etc. and even then the focal distance is far too short to be of much use.

Patience is a virtue when it comes to getting bargains

I trust that is a genuine license that you bought.

(There are a number of fakes being sold at the present time).

Tangent Corner / Re: Variable Speed control through Mach3 For Daytom motor?

« on: September 06, 2010, 11:13:42 AM »

Dave,

I have never tried one of these but it should work.
It isolates the pot control from the live parts within the KB type controllers and operates from a computer (Mach) PWM signal.

It could be a much cheaper solution than the inverter drives I have just been looking at.

Dave,

Not much help really but, looking at the circuit for the KB speed control, it is live to the 115V so there is no way to alter it or tap into its internals without providing isolation etc. not impossible just difficult.
I think it would be better to look for an alternative which already has the 0-10V input. I will do a bit or searching and see if I can spot anything.

Hi Rikk,

Having read the info on their website I think this controller is primarily intended for their own software and I think you would be struggling to try and get this to work with Mach.
Their machine conversion kits look excellent so why not use their conversion parts but fit Gecko's for the machine control. These work really well with Mach and have good backup service if required.

Just a thought.

Just for fun and big enough to engrave a telephone number.

Dave,

Do you want Mach to control the speed of this new motor or just switch it on and off  ?

Something that would be nice is a 'progress bar'.
Large DXF's take some time to process - sometimes it works OK sometimes it locks up - a progress bar would at least let me know something is happening.
