thank you i downloaded Robot Arm #2EZER v20 v9Longer.f3d
"Bottom Left Ring Holder (1)" would seem to be the body that i need to change bolt hole spacing
for nema 34 motors 31mm to 69.7mm spacing frame size from 42 to 86mm (2.04 scale)
but cant seem to find the sketch for that body simple scale up leaves bolt apace at 63.24mm

Not sure what your asking, but I designed that file with only a couple of month experence in fusion360. Its a little rough...

making a scale up version but i noticed the "Robot_Arm_EZER_v20_v6.f3d" is for the normal arm
is there any chance you could up load the long part version
simple 2.04 to 1 works for most of the parts just the motor mount holes to change in fusion360

The link near the bottom should get you a download for that file. Let me know if that works for you

S3D keeps wanting to add an extra layer in the middle of the long middle backlash model and the rings. I've tried repairing with netfabb but still, the layers remain. Any ideas?

Fixed this issue by sinking the parts into the bed by 0.2 mm.

Hi, May I ask you a few questions?
1) Do arduino mega work with it?
2) Is that I need to measure the distance of my printed product and fit in teh values to the arduino programme?
3) Where can I buy the button board?
P.S. I printed the robotic arm in short version.
Thank you so much.

hi, i have printed all parts and assembled the robot arm. For the first test, i use the drill as a motor, just like what you did in your video, the torque output is just 600g for 15.24cm, it is just 0.09144 kgm= 0.896 nm, the reason behind that is i just use 20% infill for the 3d printed arm, it cannot hold the 66:1 gear firmly, just like your video shown on youtube (18.3nm max torque test video).
I am now reprinting all the part with 100% infill, but i have some questions.
Q1)There are two files which have two different but similar names, A_Center_Ring_Holder, A_Center_Ring_Holder_Anti_Backlash and B_Thin_Side, B_Thin_Side_Anti_Backlash. Although the file names are different, the stl files are actually same shown in Simplied3d, is there really any differences between them??Or uploading wrong stl files??
Q2) Where are you from?? just curious to know

The anti backlash files have the notches moved by a few degrees. It baiscally binds the gearbox up a little bit to soak up the backlash

thx !! So i will use Anti_Backlash files to get better performance, thx!!

which is the top of the new design
End Effector holder does not have a mount for the motor

I did some updating to my instructions, I suspect that you didn't see that the rotating base has its own motor mount, because it was located in the EZ print design parts, and that became obsolete. I moved it to the rotating base "Thing"

You need to attach the "B" style joint to the rotating base and print out that motor mount for the base and then everything else will work out.

will the code work so i can use 3 joystick to control it thank you .

can u show a video on to how to put base together pls

what model s the big black on ebay they have 5 volt one not 12 volts

what about the wiring and the boards to control

is this one i need Bottom_Half_of_Joint.stl

on the new design thanks

Everything you have asked me for is here: https://www.thingiverse.com/thing:2153317

The Program, The End Effector, Motor Mounts.

I just didn't want to double upload a bunch or parts I guess

EZ Print Modular Robot Arm

what do i print the attach the stepper motor to move the gripper to arm thanks

for this do i print the Bottom_Half_of_Joint and Top_Half_of_Joint_V4 from Modular Robotic Arm, Hinge Joint, No Hardware and the Robot Gripper base then good to go

what stepper motors u use pls thanks from ebay ok

what part do i need to print pls mate all off them
