What is the recommended temp for a 80mm spindle? I run a cpu cooling system with my spindle and control coolant flow speed and radiator fan speeds. I have two inline temp sensors, one directly out of the out flow of the spindle and one connected to the inflow of the reservoir, just after the radiator. I’ve never seen over 85°F. And thats with the fans and pump only running at idle speed.
Usually 21c is the sweet spot for a spindle.
They can run cooler and much hotter.

Did you see my comparison test video? Just posted it this morning, maybe it will help

I did see it am now very jealous that I don’t have one and still will have to wait to order one. I knew the 80mm 2.2kw spindle was going to be better with loading. What I wonder is how small of a tool diameter that can be ran on it though? I have endmills as small as 1/32" and if the er20 collets don’t go down that far to accommodate these endmills, then I may be a little hesitant in making a purchase.
But I do like all of the other options this new spindle offers. I dont see anywhere though where it is offered as a kit with the cooling system that was talked about earlier.
Is this what you are looking for?
ER-20 collet sizes run from 1mm up through 14mm or 9/16".

Thanks for everything that I needed to know. This was very helpful.

100%, especially if it had a decent tool capacity.
Any word on when the 80mm standalone mount will be available for the S5 Pro? I see that the gas strut is now available for sale on the website, but the mount is lacking. I have 3 phase power in my shop so I would need a different VFD than the 220V offered in the kit.

I would recommend adding a link in the 80mm Spindle Mount for the S5 Pro product page to the gas strut kit. They should probably be bought hand in hand.

Sweet, i missed the gas strut was available, just ordered one for my S5.

Got my gas strut installed today. Simple and perfect strength.
Been running my spindle for over a year now. And have had to reduce z axis speeds due to lost steps. This should fix that. And it doesn’t drop when powered off. This should mark the e stop useful again.

Well I spoke too soon. With the strut installed I’m loosing steps rapid up at the top of the stroke. Even with my reduced speed.
If I remove the strut and leave the arm it jo longer does it.
Have you lubricated your Z axis ballscrew and linear rails? I’m also wondering if the Z rails are set 100% perpendicular and maybe you’re getting some binding.

If lubrication doesn’t help, let us know at support@carbide3d.com and send us photos showing how the gas strut is secured to the carriage.

They were lubed two days ago.
I’m not seeing how binding I’m another component can do it.
If I remove the strut. Add add additional load to the motor the issue goes away, just like the last year.
It only does it at the top of the stroke when rapid moving up, not down at all. It’s like it’s not reacting fast enough and crashing and loosing steps.

Please drop a message to support.
On a side note please make sure you are running default settings. The struts are designed for the speeds and feeds set in CM

So how big a bit is it reasonable to use with this spindle? Eg would a Whiteside 6620 2” diameter surfacing bit or William Ng’s “big daddy” spiral cutting pattern bit (1-1/8 diameter, 3” long) be useable and safe? I wouldn’t use either hand held, if that’s any indication.
New to CNC, wondering how many of my current tools will translate.
