Hi Gerald
The output shaft is so close to the edge I assume that there will be an intermediate shaft.
Just been fighting with image resolutions and adding photoes.
I think it has been attached...
Ps the adjustable z Limit proxy and target can be seen in the photoes.
Cheers

AH HA The second photo was vertical so was tripping on max size..

I like your placement of the Z limit proxy. I bet there is about .020 clearance between that adjustable flag and the spider. Nice work.

Hello Sir,

Thank you for your inquiry about our cnc parts, we'd like to make the best offer as below:

1, 86HS9801 stepper motor: USD48.00/pc. x 4 pcs = USD192.00
2, DM856 stepper driver: USD65.00/pc. x 4 pcs = USD260.00 (DM556 stepper driver: USD58.00/pc. x 4 pcs = USD232.00)
3, Timing pulley 15XL: USD9.00/pc. x 4 pcs = USD36.00
4, Timing pulley 72XL: USD26.00/pc. x 4 pcs = USD104.00
5, Timing belt 300-XL-10 (length-XL-width): USD4.00/pc. 4 pcs = USD16.00
6, HF spindle DTS-23: USD238.00/pc x 1 pc = USD238.00 (HF spindle DTS-27: USD800.00/pc x 1 pc = USD800.00)
7, ER20 collect chuck: USD6.00/pc x 3 pcs (each size is ok) = USD18.00

The leadtime for the production is about 3 weeks.

As for the stepper diver, if you would work it with 86HS9801 stepper motor in high speed, it's recommended to use DM856 as the voltage is higher so the motor can run stable at high speed.

Also for the HF spindle, it's depends on how much power you need, because DTS-23 is 2.2KW and DTS-27 is 4.5KW, if 2.2KW is enough for you, DTS-23 is ok because it's the most pupular sale spindles.

To ship above quantity by DHL to you, the shipping is about USD191.00, with driver DM856 and spindle DTS-23 selected.

Also we have seashipment to Holland every month, if USD191.00 is too high, we can ship the goods by sea to our Holland office first, and then our Holland office send those goods to you by truck, guess that's much cheaper.

This above is offer sent to me yesterday from http://www.driver-motor.com

34HS9801 = 86HS9801 they are the same

Hi Lubo
I have four 34HS9801-G5 MotionKing stepper motors as shown in photos above. These have built in gearboxes 5.32 to 1 ratio as discussed above.
I have had no failures so still have not pulled one apart.
Little backlash.
ran 5 hours yesterday cutting 10mm thick Aluminium. :)

Cosider a full set of collets. (My local shop charges about $26USD each)
Consider a spanner to suit collet
Cheers
