Re: Thor, or should that be Zeus?
Bad luck Chaz
However I do seem to remember posting this about a week ago (post #283)
"However my personal preference on big powerful machines is to have the home switches inside the boundries set by the limit switches, and have the limit switches trigger powering off of the drives. Also to have the limit switches within the boundries of mechanical stops that limit travel before ball screws over travel."

Hi Andrew, would a latched relay be suitable to perform the functions you describe?

Andrew, yes, point made. I thought of the same.
Desertboy, fairly easily done with the CS Labs. It has sub 100ms error checking and can instantly disable the servos in a fault / trip condition.
Re: Thor, or should that be Zeus?
I think the main point is to have a physical limit to save the ball screws if there is a runaway - preferably with a hard neoprene or other suitable plastic buffer.
As for the latched relay then yes that's the easy way to do it, but it needs to be a fast acting relay.
Re: Thor, or should that be Zeus?
Suppose this means it works.

Speeds and Feeds
24000 rpm - 6mm endmill
Cutting Rate 4000mm/min
Lead / Ramp at 1440 mm/min
This was run at 80% speed. Overall happy with the cut considering there is no finish pass.
DOC is 5mm, WOC is 1.2mm
Still got more to do, but happy with the initial results.

Please, ill make a plan to come and collect. Dont chuck them please.
Re: Thor, or should that be Zeus?
I haven't felt any disturbance in the force yet, I think you need to up the ante.
Milling cutters start to perform around 3/4" diameter and up, anything less than that is squidgy :very_drunk:

Agreed.
Just did some test cuts, 10m/min with 10mm endmill. 0.5mm Stepover (wimpy, im still testing) and around 20mm of depth. The surface finish is superb.
Re: Thor, or should that be Zeus?
Will do some more cutting tomorrow with 10mm endmill.
