CNC 3018 Pro Engraving Machine Collection

Recently I bought a Chinese 3018 "PRO" Milling / Engraving CNC (https://www.aliexpress.com/store/product/CNC3018pro-withER11-diy-mini-cnc-engraving-machine-laser-engraving-Pcb-PVC-Milling-Machine-wood-router-cnc/214974_32918305989.html?spm=a2g1y.12024536.productList_11474571.pic_4) and felt the need for some upgrades. After searching the net I found very few parts for the PRO model, so I remixed some parts from the 3018 standard model to fit in the PRO and I designed the end stops holders.

Some Features:

• End stops are adjustable, so you can position them to fit your needs;
• 3 types of cable guides: rail holder for thin cables, for thick cables and double side tape holder;
• Electronics Box: Thicker wall and a little curved on the bottom to give more strength;
• Electronics Box 2: 4 holes on top to hold the offline controller.
• Motor handwheels: Size adjusted to fit between the screws of the CNC.

Credits and a big thanks to:

Obs:

• The switches I used are "big" because I could not find any smaller nearby. The only micro switches I used are on the Z axis and they are bolted to the structure all the other parts are screwed to rails or fixed with double side tape.
• After you install de end stops you should tell the CNC that it has end stops. To do this you must send command "$21=1" to the board. More info here: https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration#20---soft-limits-boolean
• Once you activate the end stops the Offline controller stops working, to make it work again you must use "$21=0". If you know a way to make it work with the end stops enabled, please let me know. ;-)
• I've add 2 switched on the box cover. One for the box fan (It's a bit too loud) and another for the Spindle (safe precaution) Both were add with a soldering iron after the box was printed and that's why there are no holes on the part. :-)
• The end stop switch holders for the X and Y axis are different there is a Front and a Back model (Y) as well a Left and a Right one (X). Don't print the same model twice!

Edit: 22/jul/2019

As suggested by Eigengrow, here is the print list and the board I used.

Please keep in mind that I did this collection based on my CNC bought on Aliexpress (link above) and there are many clones and different electronics around. Please check the sizes before printing and if you have a different part and make a compatible part for it, consider sharing here for others.

BedClamp(A,B,C,D) - these 4 parts form 1 clamp, normally you will need 4 clamps to hold a part

Bed_Clamp_E - is for Printed Circuit Board only (optional)

CableGuides(A,B) - Almost the same, only the opening for inserting the cables is different, I used 7

(2 B and 5 A) to be used on the frame (optional)

Cable_Guides_C - To be used with double side tape. I used 5 (optional)

Electronics_Box and Electronics_Box_Cover - Self explanatory :-) - x1

End_Stop_Rail_Nut - x4 - one for each end stop (2 for X and 2 for Y Axis)

Handle_Knob - x2 - one for each Motor Handle

X_Motor_Hande - x1

Y_Motor_Hande - x1

Z-Motor_Cable_Guide - x1

Z_End_Stops - x2

X_End_Stop_Switch_Hold_A - x1

X_End_Stop_Switch_Hold_B - x1

Y_End_Stop_A - x1

Y_End_Stop_B - x1

Y_End_Stop_Switch_Hold_A - x1

Y_End_Stop_Switch_Hold_B - x1

The electronic model: Woodpecker 3.2 GRBL.

Please enjoy!
