Head-to-head
MiiCoffee DF64V Gen 3 vs TIMEMORE Sculptor 078S: The 078S’s larger burrs do not increase its stock bean load
The short answer
The DF64V Gen 3 is the more straightforward choice if its 64 mm burr options and bellows routine already suit you. Choose the Sculptor 078S specifically for its 78 mm platform and rotary knocker. Its larger burrs do not give you a larger stock bean load.
Before you choose
The reasoning and the trade-offs
The bigger machine still needs two fills for 40 g
Either standard hopper needs a refill for a 40 g recipe.
What this is based on
40 g exceeds the 30 g or approximately 30 g stock capacities.
Main trade-off
TIMEMORE Sculptor 078S
Its stock hopper is still around 30 g despite the larger burrs.

About this comparison
DF64V Gen 3 or Sculptor 078S? Compare burr size, single-dose capacity, cleanup and basket fit before paying for the larger platform.
The DF64V Gen 3 is the more straightforward choice if its 64 mm burr options and bellows routine already suit you. Choose the Sculptor 078S specifically for its 78 mm platform and rotary knocker. Its larger burrs do not give you a larger stock bean load.
Winner by situation
Start with what you need it to do
I want a 78 mm espresso platform
The 078S supplies 78 mm espresso-capable flat burrs. The DF64V uses 64 mm burrs, so it cannot meet that specific platform preference.
- MiiCoffee DF64V Gen 3 Variable Speed Grinder
- Not suitable
- TIMEMORE Sculptor 078S
- Better fit
I plan a supported 64 mm burr swap
The DF64V has documented optional SSP burr choices. A 64 mm replacement cannot be fitted to the 078S's larger 78 mm platform.
- MiiCoffee DF64V Gen 3 Variable Speed Grinder
- Better fit
- TIMEMORE Sculptor 078S
- Not suitable
I want a 40 g single-fill filter dose
Both stock hoppers are rated at about 30 g. The 078S's larger burr diameter does not make its hopper hold a 40 g recipe.
- MiiCoffee DF64V Gen 3 Variable Speed Grinder
- Caution
- TIMEMORE Sculptor 078S
- Caution
I change between beans daily
Both let you weigh individual doses and change beans between drinks. Choose between the DF64V's bellows and the 078S's rotary knocker.

What matters in practice
The differences that matter
The bigger machine still needs two fills for 40 g
Either standard hopper needs a refill for a 40 g recipe.
How we reached this conclusion
40 g exceeds the 30 g or approximately 30 g stock capacities.
The burr diameter rises by 21.9%
Treat that number as a size comparison, not a predicted improvement in coffee.
How we reached this conclusion
(78 ÷ 64 - 1) × 100 = 21.875%. Burr cutting area and tooth geometry are not calculated.
The S suffix changes suitability
An 078 and an 078S are not interchangeable purchases for espresso.
How we reached this conclusion
TIMEMORE distinguishes the stepped 078 from the stepless espresso-capable 078S.
Choice A
MiiCoffee, DF64V Gen 3
DF64V Gen 3 Variable Speed Grinder
A compact 64 mm flat-burr single doser that adds a brushless motor and broad speed control for people who enjoy testing extraction variables.
- Best matched use
- Advanced home baristas who will use motor speed as part of recipe development
Checked facts
- 64 mm Red Titanium flat burrs
- Speed adjusts from 800 to 1800 rpm
- 400-watt brushless motor
- Plasma ionizer and stepless adjustment
Choice B
TIMEMORE, 078S
Sculptor 078S
The larger-burr Sculptor keeps the same small-dose routine as the 064S. Buy it for its 78 mm platform, not because you expect a bigger stock hopper.
- Best matched use
- A larger flat-burr platform for espresso and filter
Checked facts
- 78 mm espresso-capable flat burrs.
- Stepless adjustment and 400 W brushless motor.
- Around 30 g standard hopper.
- Rotary knocker and approximately 57 mm catch cup.
- Automatic shutoff after 60 seconds.
Meaningful differences
What changes the fit
| What changes | MiiCoffee DF64V Gen 3 Variable Speed Grinder | TIMEMORE Sculptor 078S | Why it matters |
|---|---|---|---|
| Flat-burr diameter | 64 mm | 78 mm | The 078S diameter is 21.9% larger. That is geometry, not a taste or speed result. |
| Stock bean load | 30 g | Around 30 g | Larger burrs do not remove the need to split a 40 g batch. |
| Motor rating | 400 W brushless | 400 W brushless | Matching rated watts do not establish equal torque, energy use or grinding speed. |
| Chute clearing | Bellows and magnetic chute | Rotary knocker | The daily cleanup motion is a more concrete difference than speculative flavor claims. |
| Auto-off behavior | Manual stop | 60-second timed stop | The 078S stop is not a bean-empty sensor or weight target. |
What you give up
Every choice has a cost
If you choose MiiCoffee DF64V Gen 3 Variable Speed Grinder
- The brushless variable-speed motor adds complexity that fixed-speed grinders avoid.
If you choose TIMEMORE Sculptor 078S
- The 078 without an S is a different, filter-focused grinder.
What matters in practice
How to make the call
Pay for the platform you will use
A bigger burr number is not a reason to replace a working setup by itself. The 078S makes sense when you have deliberately chosen its burr platform and want its knocker-based workflow.
Do not infer results from watts
Both current models list 400 W motors. That removes a misleading spec-sheet argument, but it does not make their motor control, burr geometry or output equivalent.
Keep the exact model visible
Older DF64V listings can describe a different generation. Likewise, a listing shortened to Sculptor 078 may be the filter-only version. Those distinctions matter more than color or accessory bundles.
What this comparison cannot tell you
- Specifications describe the listed version. They do not establish a taste ranking or measured retention in your kitchen.
- Check the exact model, US electrical version where applicable, seller and included accessories before buying.

Match countThe count uses the current product-to-need assignments for “Precise adjustment for espresso”, “A measured single-dose routine”, and “Motor speed control for deeper tuning”. A need with no documented match does not count.
Calculation noteOnly products with a published numeric burr diameter are included. Burr geometry and alignment matter as much as diameter. 28 of 39 models have comparable published figures for context.
