Hood..   Is that you causing my workshop lights to dim down here in Dorset?

How you getting along anyway?

Brian, what are the advantages of using these more expensive drives.
Why not just Gecko or Rutex drives?
The drive specs for the Tek 10's are practically identical to the less expensive
counterparts.  The gecko's are big enough to drive any Bridgeport knee
mill that was made, of course providing the servo is a proper match to
the Gecko.

Not Brian I know, but have some experience of both Gecko G3x0 drives and the Tek10 drives.   The latter are much more spohisticated.  They have all 3 PID terms available for adjustment, alterable following error trip point, and differential encoder inputs.

The Gecko's I have used with some success right from the earliest ones, but put a high count encoder >500ppr and they can be almost impossible to keep out of a fault state!   The +- 128 count tip can be a little tight.   I last tried them with 2500 ppr encoders on my hardinge, it was impossible at near 80v.   The Tek10 drives have been easy to setup.

Rutex seem to have similar specs but I heard support can be hard to pin down, and I've heard of more than a few blowing up.

For the SEM motors on these older Brdgeports I do think the TEK20 is still not man enough with it's lower current rating.  Those motors can draw serious current.

Might be better off with TEK10's at full power (25A) with a lower voltage (slower) than loose to much torque at the 15A available on the TEK20's    I just noticed Teknix do not even list the TEK20's on their website now!

What is the cubloc having to do in your application?   Are you using ladder or basic in the Cubloc?

Roo.

Sorry don't have a macro for the HXL yet.   It's been a project stalled for a while!   Must try to make ammends though, as it's killing me seeing it stood idle while I'm working on the manual lathes next to it!

The HXL turret works in a completely different way anyway.   It's stop is fired before it's lifted and idexed.   The HXL turret is single direction and sequential.  Unlike yours which can go to any position in one cycle.   Ever seen a HNC lose an edcoder?  I have!   Helicopter rotor springs to ming LOL...

I do think though, that VB script may not be responsive enough to fire the stop in time.   You may have to spring for a PLC and a little ladder code to do what you require.  A PLC will have no trouble.

Sorry can't help with the turret as they are quite different to the HXL turret.    Have you had the encoder working?    All I can remember is Brown wire is +5v and Black is 0v.   Maybe BCD output on those.  I lost my service manuals for those machines years ago.

Making chips eh?   Video it we want to see!


Good Luck

I shall try ordering from their site.

The price in the UK for the 280 device works out at $79   Daylight robbery eh!

Glad to see this thread.   I had independantly discovered the Cubloc devices a few weeks ago but had not realised they had Modbus!

I will have to get a few of these in I think.   Although I hope to buy direct instead of from a UK supplier which typically makes the price 1UKP per $ Which I despise!

May be able to retire my homebrew PicAxe based ATC controller, which sufferered from Mach not having RS232 Rx n Mach's VB Scripting.

The Cubloc is the Product ModIO should of been.  I always thought that although an Admirable product it was let down by not really being programmable, but rather just  io remapped to modbus registes.

I hope to join in this thread when I got my Cubloc's   Got some serious work ahead I think!
