I like it!

It looked like a terrarium at first because of the light.

Time to feed the 'Oko!

Yes you right, its an 50x80 IKEA IVAR shelf, i have to cut out some wood of the rear wall because the shapeoko is to big in width. the Box is only to protect the room from dust and the main reason is: my wife said that she doesnt want a cnc mill in our appartment. but we make a compromise: when i integrated it in the shelf, its okay for her :)

mission accomplished

Next Step: Building up a derivate of the xStepper or GRBLmainboard, how i call it.

Well, I've been quite patient for mine to arrive, but now, I know that I'll be dreaming about eShapeOkos this night! Wonderful build, full congrats. The enclosure is very nice. Mine will just sit on an MDF table within an acrylic box! (Yes, I also have a wife and a flat - but she doesn't know yet about the dust and noise :mrgreen: )

eShapeOko #??? now in the postal tubes
dual y drive, dual x rail, all nema23, alu spacers, grbl on arduino nano, home made controller, crappy 40W spindle.

10.01.2021 - New eShapeoko & new Build

In 2013 I bought the eShapeoko for the first time, in this post I documented my setup back then. Now this is about 8 years ago - my Shapeoko I have sold about 2014 (buyer unfortunately unknown) - I was now very annoyed when I have dealt with the topic CNC again a few weeks ago.

The more I was surprised that in Europe still the eShapeoko is sold by Catalin - my joy was really great. I have therefore directly bought a new set and built this in the last 7 days.

This I would now like to share with you again. I am really pleased that the Shapeoko is still a topic - even if in the meantime CNC machines from China have spread far (and unfortunately also cheaper, but not better).

My eShapeoko is 500cm x750cm and will soon be powered by a Makita spindle. My first one I still had with a Dremel but now I need something real.
For the electronics I bought small mini boxes from Festool and built a power supply and a controller box. The stepper motor plugs are still to come.

Welcome back!

Using the Systainers is delightful!

Looking forward to seeing what else you'll make. You'll love the Makita --- it (like the Carbide Compact Router) is the best value in a trim router as spindle.

21.01.2021:

- I finished the Controller Box and added suitable plugs for motors and limit switches.
The basic idea is really to be very quick in setup the machine because I need to store the machine in my garage when not use.
So i will put it out, easy connect it to the sustainer controller box and can run the machine.

- I did the first test run with a pen writing names of my family members. The quality and precision for that was really okay for me.
I will study more when attaching the spindle

- My next task is wiring and limit switches. Y- & Z-Axis is already assembled but I need to extend the DUPONT wires with additional connectors.
Additionally I will add now energy chains & X-Axis Switch.

- After having the homing feature I want to study more the precision.

01.04.2021:
the last 3 months has been very instructive.
1. it started with me having problems with the endstops - I could trace it back to EMC influence on the CNC shield V4. as a solution I built an opto coupler circuit. This works

2. then I found out that the X-axis is too weak from the motor power. I have installed new larger and more powerful motors. The maximum what NEMA17 and 2A give.

3. after that I found out that not only the motors were too weak, but also the eccentric bushings were too tight, the motors did not manage to move the machine when there was also a load on the Z-axis.

4. after readjusting the guides, cleaning them and readjusting the new motors, I achieved the first good milling results.

5. now I notice that during roughing the feed is probably too fast for the motors and they do not build up enough torque. I work with 450 mm/min at 3mm cutting depth (2 flute wood cutter in 6mm with medium hard wood). I have to screw on the parameters because I do not want to mill slower. Otherwise simple parts take forever.
