I am trying to upgrade my MPCNC.
As a first step I lowered a few days ago at half the z axis cutting length from 19cm to 9cm.
In my machine i have an arduino shield with an arduino uno (I am running gbrl) and my steppers are at 0,9 angle at 1,7A per coil with a holding torque: 48N.cm - 4.8kg.cm.
The new that I have ordered are at 1.8 angle , 2,0A rated current and a holding torgue at 8.2 kg.cm.
Do you believe these steppers are a significant upgrade in the strength of my machine ? Today I am facing often issues in hard materials even if a slow down the feeds….
One of my main concerns with the new steppers is the current limits.
I am jumping from 2 steppers per A4988 at 1,7A current to 2 steppers at 2A.
Do you thing that i will be ok and i will not burn the system ?
