because you need to set a feed rate before the first G1 command . GRBL boots with feedrate = 0 so you have to tell it in your program what rate...
do not use version 0.8, 0.9j is MUCH better Motion directions as in the image below (what Mark said) are 'tool motion' so in the image below for...
Many CNC controllers have a timeout after which they will disable the stepper drivers. This is great if your motors get too hot because you are...
You need one or more of: more voltage, more current into that motor, less microstepping, lower speed, lower acceleration, more cooling. Do you...
Always ramp in aluminum.
Hi Don The industry standard is (for milling machine, usually) Z up X right Y far away that is machine home, and if you are using GRBL, that is...
I'll beta that (-:
Please use the latest GRBL, it has many bug fixes and new features that will make your machine run better. It is also hard to answer questions...
A safe way to find out what the steps per mm value is would be to set the value 'too low', say 10 (or even '1'). Now command a move and measure...
Definitely some sort of bug, might be related to pocketing faces that are very small. Pretty much the wrong tool for such small faces though. I...
So you want all the little circles to make a hole 0.313" in diameter and 0.375" deep? and you are trying to pocket all 72 holes? Well, I didn't...
Stepper power drops off sharply with increased microstepping. This is why you will see me say 'use the lowest microstepping that gives you the...
See the little hourglass shape in the middle of the drawing? that is the X0Y0 point. If you prefer to have bottom left at 0,0, then you can...
Here is a plot of my G-code using plunge holes. [ATTACH] With ramping on at 10 degrees, the bit will not plunge straight down at any time,...
right, just looked at the gantry inside plate Robert Bailey posted. He has coded it for SketchUcam but using a rather odd size bit. If you need...
Now that is a million dollar question.... one I don't have an answer to. I am an IT geek and DXF has defeated me many times over the years. I...
I am guessing you are exporting DXF from Sketchup and importing it into Estlcam, right? DXF is unitless, you have to set the import units before...
Note just an idea, but actual math (-: C-Beam™ Machine - Plate Maker You will need to measure the actual kerf size and use that for 'bit...
also look at Moag's design Moag's CNC Mill
Hi Calculating the steps per mm settings is easy, see C-Beam™ Machine - Plate Maker The leadscrew is likely to be spot on from the calculation,...
