Eggduino aka Sphere-o-bot aka Eggbot Copy Build and CNC operation.

The Eggbot copy or Eggduino sometimes referred to the Sphere-o-uino is an Arduino, CNC shield, 2 stepper drivers, 2 stepper motors, a servo, swing arm and a 2 axis rack system that can read paths from Inkscape and convert them in CNC paths so as to plot an ink pattern onto the shell of an egg or sphere.
There are many iterations of the project, official and otherwise. This particular design is for the NEMA 17 Stepper Motor, A4988.

Thank you! Thank you! Thank you! Mat, you saved my ass. I bought this from aliexpress and it came with NO instructions or software. Watched your video a couple of times, added the capacitor which was NOT in the kit and got it working. Thank you!!!!

[@rickbrasche8781]

you are my new hero! seriously was taken aback by this chinese eggbot kit having not the usual difficult to decipher instructions, but none at all. I guessed a lot on the physical assembly but had no idea how to make it all work. only found your video after searching under "arduino cnc shield" as "eggbot instructions showed me other eggbots that required soldering and 3d printing and other stuff that didnt apply to this kit. But two weekends later, Im drawing on eggs. images dont look as nice on the egg as they are in Inkscape but Im sure some more physical adjustment will help. thanks for this well detailed instructions!

Isn't it linked to three github address?

[@rickbrasche8781]

@@w33va not the one I found. there's gotta be more than a dozxen now and more clones/copies all the time

[@eduardos.p.2836]

thank you for your explanation, help me a lot

My motor is still shaking again, not smooth
The first solution is to unplug the usb and plug it in again
The second method is to enable and disable the device manager
I wrote a powershell script, hoping to help people who have the same problem
$instanceId = (Get-PnpDevice | ?{$_.friendlyName -match 'CH340' -and ($_.Status -eq 'OK') } | select-object -first 1).InstanceId
Disable-PnpDevice -InstanceId $instanceId -AsJob
Enable-PnpDevice -InstanceId $instanceId -AsJob

[@ScottWinterringer]

is there an instructions manual for assembly. Also what capacitor did you use referenced around 8:56 for autoreset, gnd to rst, should we tune the pololu's? [I imigine drop in "modern" replacements would be desirable] then the last question is I assume I can tap the 12v line and use a pc fan mounted on

[@w33va]

100uF. I would use the newest component versions, as you may need to recheck your libraries both ways anyway. (Components and libraries update) a fan should be fine but you may want to put a diode on the circuit in case of reverse election flow.

[@baehr4308]

Where can I find the share folder, so I can change the PID??

[@pigua7705]

Every time you send gcode, you have to plug and unplug usb, otherwise it will be shortened. Have you encountered this situation?

[@w33va]

No, but you do need to shift that jumper. Maybe check the cable

[@pigua7705]

@@w33va Maybe I should try your eggduino version. You work great ！
