Looking for high temp z axis stepper motor  

High temp;

LDO makes them and Filastruder sell them:

Look at the chart.  

RE: None have Long Lead Screw?

@cwbullet thanks for the information but none of those have the long Z-Axis lead screw. Can you or someone help me with finding the stepper motor with the longer lead screw?

try here!

Suggested Z-axis motor has no temperature specification

@JoanTabb thanks for the information but this motor does not have any temperature specifications. I am looking for a High Temp motor like 180 degree C so I can run my temperature chamber at 90C. Can you or someone help with this?

RE: None have Long Lead Screw?

To drive the Z-axis trapezoidal spindle, I used motors from Stepperonline (or others of your choice with 5mm mounting) and a clutch:

TR8x8 or similar trapezoidal leadscrews are available in any 3D printer store.

hot stuff

Drop then a request for info... 

I believe they are LDO Motors

your expected temperature range seems high!

regards Joan

Good Idea Karl

I was thinking about that coupler/clutch but I am not familiar with how good they are. @karl-herbert Will the clutch get in the way of the z-axis going all the way down? And is there any wobble?

I will contact them for specifications

@JoanTabb you are very helpful. I will contact them. @JoanTabb Also what is the best temp chamber temp for ABS/ASA. I assumed the thermal expansion would decrease with a higher chamber temperature. So I though 90C would be best.

That is very much like the Ender 3 and should work.  

Thanks Karl

Thanks for the information Karl

RE:Good Idea Karl

No wobbling as long as the stepper axle runs smoothly. The stepper can be moved down or mounted on top.

Karl

Thanks for Clarifying Karl

@Karl Thanks for the detailed drawing. I didn't know there was a ball inside.

RE: Thanks for Clarifying Karl

Due to the design of the clutch, the ball should compensate suspensions in Z-direction. Alternatively, you could use claw clutches (I use them on my CNC milling machine).

Karl

Pass...

Sorry, I don't do ABS or ASA. 
ABS gave me breathing problems
regards Joan

Thanks Karl

Thank you again for more information that will help me connect the stepper motor to the Lead screw.

Thanks Joan

Thank you Joan for answering questions. Understood about ABS breathing problems. 

ABS, ASA, HIPS - harmful to health ?

Some plastics emit toxic fumes above the melting temperature, which can be harmful to health (styrene, caprolactam, lactide, ultrafine dust...). PLA and PETG are less harmful. Unfortunately, there are fewer studies on this, so it's better to work in a well-ventilated environment when printing.

Good information.  I think I would say that some filaments “may be harmful” to your health.  We need more data, but it is clear that some are more susceptible than others.  I would strongly recommend using your printer in areas separated from you main living area and in enclosures with filtration if possible.  

90C is crazy too hot for enclosure target

That's 194 degrees Fahrenheit - no need for that to print ABS.  When I print ABS, my enclosure temps get up to 35, 36, sometimes 39 c.   Save yourself some time and money - you don't need to go that hot to get great ABS prints.  What you will need is a ventilation system that takes the styrene gas and vents it through filters and then outside.  I built my evac system for a couple hundred bucks and only had to drill one 4 inch hole through the outside wall of the house.  Double duty by splitting the evac between the paint booth and the enclosure.
