Source: Kress 1050 42, 43 mm motor mount?

Post by med » Fri Mar 07, 2014 1:15 pm

Hello,

where to source/buy Kress 1050 motor mounts (diameter 42 mm - 43 mm) for the eshapeoko/shapeoko2?

In viewtopic.php?f=8&t=722/viewtopic.php?f=8&t=722 are already some mounting options included, but I don't have the opportunity to make mounts my self.

ciao

Hello,

I had my Kress 800 mount custom made on a french forum. So I can't help you with the sourcing.
The mounting diameter was 43mm for me.

That latter looks kind of interesting, since it seems to be designed to be easy to mill (but then requires some additional right-angle bracket(s) to fasten it?).

Might be a useful design for someone to expand upon for a simpler-to-fabricate spindle mount.

@PsyKo Do you have a dxf or other source of your mount? Ciao

No Dxf but this drawing. Everything is in millimeters

As far as I remember this is the first sketch. Some adjustement were made such as the spacing for the 4 screw that tie it to the makerslide.
The 30mm was bigger to accept rounded corner around the screws, etc... Sorry I have nothing better.

I bought this mount for my Kress 1050-1: http://www.mechastep.de/product_info.ph ... -43mm.html. Pretty solid for the given price. The first mount I bought somewhere else was a fail. It can not be mounted, because the spindle is too close to the overlapping Z-axis motor (I guess the prior mentioned mounts from Damen-CNC will have the same problem). The Kress spindle is longer than most of the other ones discussed on the forum and has to be placed more far away from the gantry.

But the Mechastep mount is perfectly fine, it just need two additional screw holes to fit the Shapeoko front plate. The Mechastep-mount also has some additional screw threads for later extensions (e.g. dust-shoe). Would buy it again...

Could someone provide, or point me to the specifications for this spindle? I'd love to add it to the wiki.

Actually, there are two versions of the Kress spindle:
  • Kress FME 1050 - 1000 Watt (10.000 - 29.000 RPM)
  • Kress FME 1050-1 - 1000 Watt (5.000 - 25.000 RPM)
The official vendor page is: http://www.kress-elektrik.com/Power-too ... id%5D=1035

Personally, I bought the FME 1050-1, because many claimed that the lower speeds are preferable for cutting plastics and soft materials. And 25.000 RPM on the top end are enough for all the harder materials that can be processed with an Shapeoko.

I took a few photos to illustrate the motor mounting problem with the SO2 and the long Kress mill.

This was the first mount I ordered:
Image
As shown, it can not be used, because the spindle interferes with the Z-axis Nema motor.

In addition, it is also too wide for the mounting plate. This is no real problem, but also nothing desirable.
Image

This is my current motor mount from the shop mentioned above:
Image
It is placed more far away from the mounting plate and perfectly fits the gantry (only a millimeter space between mill and z-axis).

In addition, it also has exactly the same width like the mounting plate:
Image

Here are the two motor mounts in comparison. The black one is too tight and the silver one fits perfectly:
Image

For the Kress mill, the beginning of the mounting hole needs to be at least 43mm away from the gantry plate (measured by me). As a final disclaimer: I have not mounted the motor yet. Therefore I have no real usage experience for this mounting solution. But at the moment I am not aware of any problems that might occur.
