Triac ATC mechanism wanted.
Has anyone got a complete triac ATC mechanism, that has been removed from a machine and no longer needed? I dont need any control gear just the mechanics, I am in the midlands region.

Tony

sure,but to be honest id rather you take the lot with you,ie the tray with everything minus the motor controller,which works!!
make me an offer i cant refuse! as it will save me ebaying it all can you pm me?
tony

ive got 3 drives and the xand y steppers no z stepper
steppers are mae? I assume it all works when you power up the base the screen comes on with no error messages?
Tony

Ok what bits exactly do you want?

Angel,
Im in worcester,whereabouts are you?

Ok found the manual it all looks straight forward,hope it works,as i havnt put power to it yet.
if not Ive got a eurotherm 508 that should do the job.
is there any market for all the original triac electronics? as im mach3ing this with new steppers and drivers?
Tony

No its a linx 80, is that good or bad?

Dale,
I am looking to do what you are doing on a friends machine.
How have you got on with it?
succesfull?

The little 24 volt scooter motors work very well,there 6 amps and will take loads of abuse,plus you can buy them off ebay for about £10 brand new.
As far as "cogging" goes there not to bad, yes proper servos have skewed ...

"Permisable error" is misleading,the servo drives will push to try and get to a zero error. if not then you have a problem.
as far as "overrun is concerned I have always found that the problem is more likley to be the axis slowing down or braking under friction and having the ramp up/down set to ...

Steve,
my encoders have 2000 counts(with quadrilature) I have never noticed them jumping about,even using the 5xmultipler (400 counts) dithering is not noticeable.
I am sure steppers are fine for training machines or positioning non loaded objects.
The differance being,I suppose that I earn my ...

yes, I think this Video gives you all the reason you need to use gecko g340's and servo motors,I wouldnt entertain using steppers on a machine build/conversion now-there nothing but trouble. yes servos can be more expensive,but there are numerous ways to reduce this (attach cheap HEDS encoders to ...

Hi,
its strange how there is never a resonance problem with printers or
plotters ???

Hi,
if you undo one nut and turn it against the other then lock it back up.

Not such ...
