VzBoT VZ330 3D-Printer Instruction Manual

VzBoT VZ330 3D-Printer Instruction Manual

About

This manual is intended for the aluminum parts for VZ330 as sold by F3D-Racing and Mellow. The aluminum parts are interchangeable with the printed parts, some additional hardware is required when purchasing the motor mounts and idler mounts. Furthermore some printed parts are required in order to mount your new sexy parts!

Beware, VZ330 was never designed around AWD like VZ235. Because of this the design team was left with the frame as constraint. Due to which it was not possible to have a design that did not limit y travel for the VZ330 printhead. There is a 10mm loss in Y travel coming from 330mm.

You can purchase the VzBoT Vz330 from the following websites:

*Disclaimer: VzBoT is an opensource passion project, this manual is not definitive, and we try to make it as polished as possible. Fortunately, we all make errors so use common sense when following this guide.

Print settings:

We recommend printing all parts in ABS, ASA or similar material to be able to withstand the high heat environment in the printer enclosure.

Print settings should always be tuned for your own material and tested for decent strength and layer adhesion.

We recommend the following settings:

For non-moving parts:
Layer height: 0.2mm
Layer with: 0.4 to 0.6 mm
Number of walls: 4
Infill percentage: 40 to 50 %
Top/bottom layers: 5
For moving parts:
Layer height: 0.2mm
Layer with: 0.4 to 0.6 mm
Number of walls: 4
Infill percentage: 30 to 40 % depending on your material
Top/bottom layers: 5

AWD Motormouths/Idlers

Bom:

longer grind down the ends. Correct shoulder bolts available at mellow & F3D
GT2 Toothed idler| 2|
Gt2 Smooth idler| 2|
GT2 motor pulley| 2|

STL files:

Step 1:
Mount the GT2 drive pulley to the motor and attach the motor to the bottom plate using 6mm M3 screws.

Step 2:
Mount the 10mm M4 nuts and t-nuts to the top plate. Then put the shoulder bolts in place in the top plate and push on the printed spacers and idlers like shown below, making sure they are in their right position. The printed spacers are tight enough to where this  assembly (with some care) will stay together.

Step 3:
Attach the bottom assembly to the printer frame using 10mm M4 screws and t-nuts. After this attach the top assembly from the previous step loosely. Make sure the shoulder bolts thread before tightening all screws.

Step 4:
Insert the printed corner spacer and install the 30mm M3 like shown below.

Step 5:
Repeat the same process for the other side making sure to put the idlers in their correct position.

Firmware:

Klipper, RRF and Marlin natively support AWD for Corexy kinematics. For a Klipper example Cfg suited for AWD check the VZ235 Github page.

Setup and tuning:

After finishing the build one must take care to properly set up the AWD system. It is important to “sync the motors”. In order to achieve this it is advised to use the following macro’s in klipper:

[gcode_macro enable_stepper]

gcode:
SET_STEPPER_ENABLE STEPPER=stepper_x ENABLE=1
SET_STEPPER_ENABLE STEPPER=stepper_x1 ENABLE=1
SET_STEPPER_ENABLE STEPPER=stepper_y ENABLE=1
SET_STEPPER_ENABLE STEPPER=stepper_y1 ENABLE=1

[gcode_macro disable-steppers] gcode:
m84

Step 1:
Set belt tension like on a normal 2WD VZ330.
Step 2:
Loosen the grubscrews on one of each set of motors, make sure the grub screws will not be on the flat side of the stepper shaft.
Step 3:
Boot up the printer and order “enable stepper”.
Step 4:
Tighten the stepper grub screws and disable steppers again.
