Size accuracy issue on carving by x carve

Hello everyone,I am new to X Carve and recently i assembled an X Carve .My problem is that when i carve any object the actual output comes out 4 times bigger on all axis i.e if i put value on Z axis =3 mm it will cut 12 mm…1 mm on X axis will cut 42 mm and 1 mm on Y axis will cut around 42 mm,This is creating a lot of problem as i am not able carve desired size.Mine is 1000 mm rail size x carve,grbl values are as follows

Microstepping issue.

Describe your hardware:
Arduino/Shield or what? Can you post a pic?

Arduno Uno ,Protneer CNC Shield Version 3.5, TB6560 Stepper Driver

Remove any jumpers conserning microstepping on the Protoneer shield, if any.
Set microstepping on the TB6560’s only.
What are they set to now?

(You can also bypass the Protoneer shield entirely as the TB6560’s can be connected directly to the Arduino.)

CNC shield is set X = 1/8, Y =1/8, Z= 1/2 jumper setting… I don’t know how to connect TB6560 directly to arduno :thinking:. What do I need to do on CNC shield jumper setting??

Set CNC Shield (Protoneer) to 1/1 microstepping.
What is the TB6560 switch S3 and S4 current position, ON or OFF?

In 10 minutes I am reaching to my workshop and then I send you the pics…thnks

Since your chain is Arduino -> Protoneer Shield -> TB6560 I am unsure how any microstep jumpers on the Protoneer Shield affect things, but compared to A4988 drivers the TB6560’s have their own individual microstep settings (switch S3/S4)
