I want to build a 3D printer with a heating chamber of around 90 °C with build area 200x200x200 mm. I have never build a CoreXY system, so my design is currently an XY system with moving X motor (mounted on Y). Since it has a heating chamber I can't use normal stepper motor (there's a way, but I have to provide forced air cooling like NASA did, or water cooling). Extruder is Bowden type. I have already sourced almost all components, but I'm stuck at choosing the motor.
I could find high temperature stepper motor in India (that's where I'm from), but it cost too much. I found one at the Visionminer website, they're the dealers for Intamsys printers, which has a chamber of 90 °C and they are providing replacement stepper motors as well.
Comparing the cost, the motor I found in India costs three times as above. Even with shipping I will save a lot. But one issue is they're not providing any details about torque and current rating. There's one image in the website and it says,
MOONS STEPPING MOTOR TYPE 17HDB001-11N 60904162 18/04/12
I thought it might be a MOONS motor, so I contacted them, no reply so far. I tried to find the motor by part number, but failed. I tried mailing Visionminer as well.
Anyone have any idea which motor is this? or know any high temperature motors?
Also they use Gates belts, which is rated for 85 °C. How reliable will it be in 90 °C chamber?
