Learn how to extend your iDraw H-Version (A3/A2/A1/A0) to a larger version (e.g., 1.0m x 1.8m) for more creative possibilities. Please note that modifying the machine in this way will break the manufacturer’s warranty.
Materials Cost: ~150€
Materials Required:
The following materials are for extending the iDraw H-Version to a 1.5 x 1m size. If you wish to extend it further, adjust the lengths accordingly. However, extending too much may lead to rail deflection issues.
Material | Quantity | Length | Example Links |
---|---|---|---|
Aluminum Profile V-Slot 2040 (5mm threaded Holes), Y-Axis | 2x | 1.5 m | N/A |
Aluminum Profile V-Slot 2020, X-Axis | 1x | 1 m | N/A |
Aluminum Profile 2020 or similar, Frame between the two Y-Axes | 2x | 1.2 m | N/A |
G2 Timing Belt width 6mm pitch 2mm | 2x | 5 m | Amazon Link |
Aluminum L-Profile (for Drag Chain on x-Axis) | 1x | 1 m | Amazon Link |
Drag Chain 10x20 (Y-Axis) | 2x | 1 m | Amazon Link |
Drag Chain 10x15 (X-Axis) | 1x | 1 m | Amazon Link |
Nema 17 extension cords xh2.54 4 poles | 3x | 2 m | Amazon Link |
Nema 17 extension cords xh2.54 4 poles (for Z-Axis) | 1x | 3 m | N/A |
Double-sided tape | just a couple of pieces | N/A | N/A |
Tools Required:
- Metal Saw (if profiles need cutting)
- M5 Drill
- Tools that come with the iDraw (Hex keys, etc.)
Step-by-Step Guide
1. Disassemble the iDraw H X-Axis
- Unplug all cables.
- Unscrew the X-Axis.
- Take off the X-Axis.
- Loosen the belt guide on the opposite side of the motor.
- Loosen the carriage plates and slip them off the profile.
- Slip off the Z-Axis carriage.
- Unscrew the Y-motor splitter.
2. Assemble the New X-Axis
- Take the new 2020 profile and screw on the Y-motor splitter.
- Take the 2m cables and plug them into OUT2.
- Fix the cable into the profile with cable holders and double-sided tape underneath to keep it flat.
- Slip on the X-Axis carriage.
- Put on the carriage plates.
- Put in the belt guide, ensuring the belt is tightened.
- Install the timing belt and fix it with binders to the X carriage.
3. Disassemble the H Y-Axis
- Unscrew the timing belt fixtures as per this video: https://youtube.com/shorts/U0pMd692T6c?si=SjdmkrlpmjGwgB2y
- Unscrew the plates at the end of the profiles.
- Slip off the Y motors.
4. Assemble the Bigger Y-Axis
- Take the 2040 profile and slip on one of the motors.
- Take the timing belt, fix it on one side.
- Thread it through the motor and fix it on the other side.
- Ensure the carriage moves smoothly and isn’t idling as this video:
- Screw on the plates at the end of the axes (M5 thread drill or drill directly into the aluminum).
5. Assemble the Extended iDraw
- Lay out the Y-axes in parallel and loosely connect the ends with the remaining profiles (adjust as necessary to fit the X-axis).
- Place the prepared X-axis onto the carriages carefully (move the Y-axis to fit).
- Screw on the X-axis securely.
- For squaring, move the X-axis to one side, then fix the Y-axes on that side. Repeat for the other side.
6. Wiring Up the Extended iDraw
- Thread the Z-axis cable through the shorter drag chain.
- Thread the X, Y, and Z motor cables through the longer drag chain.
- Reconnect all the cables properly.
- Take the L-profile and install it across the X-axis.

- Install the drag chain and secure it to the carriage (use screws and wire for securing).
