The part on the last phote is the motor for the Z axis including the bearing holder block. on this photo you can see the complete machine so far.

Tolle Maschine! Schoen, dass der Brushless-Antrieb gut läuft.
the brushless drive had plenty of power it pushed 2 or 3 robots a way without a problem.
On our fb page you kan see al the fights

Thank you
This weekend we started working on our new Featherweight, Equinox. It will be a four wheel driven robot with a drum on its front. Its a bit inspired by Rango/Django.
Like Omega it will have a fully shockmounted brushless drive system. Omega is way overpowered so we chose the slightly smaller NTM4258-500KV this time.
The gearbox consists of two stages, a 3:1 with bevel gears and a 3:1 stage with a T5 belt.
The aluminium frame that you see on the last two pictures is purely as a mock-up/prototype.

Wow, this is a great work !
I'm fascinated about the präsicion of the gearbox with all "openings" .
*ThumpUp*
Looks fantastic *Want-to-have-your-workshop-plus-milling-skills*
Wow, looks great!
this is what we are building:

Status update on the bf25 mill, Y and Z axis have already moved with the computer. Now working on the X axis.
Stef, you had documented the "hardware" (=motors) for you machine.
About your fotos, ich think, you had already bought the controller and the power-amplifier for the motors. Can you give here a tip about the company and the order number? I have no earthly idea about the software to design the koordinates for the machine. Any tip for me?
A helping tip was the foto with "Dyk... steel"... => I found out, that this ist DYKEM STEEL BLUE LAYOUT FLUID and ist used to paint the metal before scanify. I was searching for such a painting.... But worried, that in Ebay and Amazon the fluid must be shiped from USA or Great Britain. (?) No offer for direct bay in Germany.
Friendly regards
the blue dyken fluid comes from ebay uk, it works so great. Wish we bought it earlier. Use that in combination with a granite block and a height meter.

On the cnc machine, last weekend did a first full test run on a small piece of alu.
Right now the hole machine is taking apart, to add a lubrication system.
the used motors for the X and Y axis are nema 24 3nm closed loop motors.
On the Z axis there is a nema 34 8nm closed loop stepper.
All driven by a usbcnc v5b quite expensive but is have a very nice user interface and we use this software also for the current cnc mill.
right now waiting on the enclosure to be made, and then the whole machine can be put back together for the last time.

Thank you Stef for the information and pics!
=> Summary-Ordering for the roboteers is put in another Thread of the forum.
today finished the oil groves for X and Y axis. Also made a start on the cable rubs.

oil groves for X and Y axis
A very luxury feature. I didn't known, that this is necessary. (One time in a year before x-mas-holiday seems to be enought. ). In my last job we used machines for testing semiconductor-wafer. => wafer-prober. The service of the company checked and "oiled" the ball bearing spindel only every year. Okay, to move a semiconductor wafer or to mill the steel needs another power....
Update on the cnc mill: Did some painting last week, now putting things to gather.

Well done! (maybe not cheap.....)
second test video, this time with mist coolant.
Thank you for the demonstration-videos.
The blow-out-function is new?
Only for my interest: Which speedfactor has the video in relation to the original-time?
Best regards
