What to know about the TwoTrees TTC6050
Room to nest a whole sheet
At 600 × 500 mm you can lay out a run of parts and cut them in one job, with holding tabs so the last ones don't shift.
Speed isn't the limit
With a 5,000 mm/min top speed, the spindle and bit set your feeds long before the machine does. The table below is worked out from chipload, so it's a sensible place to start.
Check your collet for ¼″ bits
The ER11 collet system takes 0.5–7 mm tools, depending on the collet fitted. Use a ¼″ collet for the ¼″ column in the feeds table.

Starting points for solid carbide 2-flute end mills, worked out for the TwoTrees TTC6050 preset and kept under its 5,000 mm/min top speed. They're the numbers Cut Studio suggests when you pick the bit and material.

Chiploads come from bit makers' published ranges (Onsrud, Amana Tool, Whiteside), kept at the gentle end for hobby machines. Every machine and bit is a little different: listen for chatter on a test cut and adjust.
From box to first cut
Surfacecraft makes the G-code. A sender runs it: gSender or Universal Gcode Sender (both free), or Surfacecraft itself over USB with Pro.

01
Create a free account Open Cut Studio in your browser. Nothing to download.
-
02
Add your machine Pick the TwoTrees TTC6050 preset. Check the top speed against your manual.
-
03
Make a design Draw text and shapes or import an SVG. Give each shape a depth, a cut and a bit.
-
04
Check the 3D preview It's built from the real G-code, so what you see is what the bit will do.
-
05
Download and run Load the bit the file's header names, zero where it says, and run it in your sender.
TwoTrees TTC6050 test G-code
A first cut to check your machine before you design anything: a 40 × 30 mm pocket and a 40 × 30 mm outline, both 3 mm deep, with a ⅛″ 2-flute end mill in pine. Made by Cut Studio with the TwoTrees TTC6050 preset, at the softwood numbers in the table above, and it runs in about 2 minutes.
Clamp a piece of pine at least 100 × 60 × 6 mm. Zero X and Y on its front-left corner and Z on its top, then run the file in your sender.
A set of drawer dividers
Draw the slotted strips once, copy them across a sheet of ply and cut the batch in one job. It uses the bed properly, and the 3D preview shows the tabs before you start.
