In Easel, Hit carve

Jog the machine in every direction noting which axis is reversed.

Exit carve walk through and go to:
Machine->Advanced->Machine Inspector

Scroll down to $3 and note what the binary mask and variable is. You may have to type $$ to show the GRBL settings.
Look it up on the chart above and figure out which it is. Now look for the one that stays exactly the same EXCEPT for the axis that needs to be reversed. Note which number on the left side of the chart that is.

Scroll up to the comand prompt and type in:
"$3=" and the new number with no spaces.

Hit enter.

Hit the two circling arrows or the refresh button.

Type "$$" in the command prompt. Scroll down and check that $3 now reads what you want it to.

Example:

Your Y axis runs backwards.
You look up your $3 and it says $3=2
That's X=no, Y=yes, Z=no.
The Y is the only one you want to reverse so you look for no, no, no. That $3=0.

This is my current probing macro for UGS.

M5; G17; G20; G91 G38.2 z-.5 F2; G92 z.505; G91 G0 z.03; G91 G38.2 z-.1 F1; G92 z.505; G91 G0 z.1; G90

Paste it in one of the macro fields.


CHANGE Z.505 TO THE THICKNESS OF YOUR THOUCH PLATE

it should look like this:

You need to change your dir port invert mask ($3 in grbl settings)
put in your current $3 number, click the button next to the direction the axis DOES travel. it will tell you the number to change it to in order to make the axises travel the correct direction. 

(AREA FOR FUTURE TOOLS)

Using my calculator from above and this setup, I found out that when I sent the Z axis 100mm up and down, it was off by 1.5mm. I had $102=95.50 and enter those into my calculator. The new number was 94.088. Which was very close to the manufactures suggested starting point of 94.56.

​A GUIDE TO SETTING UP SOFT LIMITS IN EASEL

Here is a calculator to help figure out what your bit size should be listed as to get correct holes and cutouts. This helps especially with bit flex that you can't measure when just cutting a straight line.

Your first step when entering in a new bit should always be cutting a single pass straight line with the bit and using a micrometer to measure the actual cut left by the bit. it's rare that a bit is actually the size it's listed.

If your cut comes out correct or is non critical, great! But if its a hole with tight tolerance and it's off, instead of changing the drawing, Know what you bit flex is. It's best to leave the geometry as designed and adjust the listed bit size per conditions. Wood hardness, bit stiffness, cut shape, speed and feeds, and pass depth all affect bit deflection. Use this calculator to make the math easy. Use a list for each bit like the following to help make accurate replications of your design when creating tool paths.

Example:

BIT: 1/8" down spiral
straight path diameter: .124
Circle path Hard wood: .120
Circle path soft wood: .123

Or what ever works for you. Accounting for bit deflection and knowing ahead of time what diameter to use can same you from scrapping and multiple try's to get it right.

*Disclaimer: If your steps per mm is off, you must fix that first.

BIT SIZE ADJUSTMENT CALCULATOR

*** NEW MACRO: M5; G17; G20; G91 G38.2 z-.5 F2; G0 z.03; G38.2 z-.1 F1; G10 L20 P1 z.505; G0 z.1; G90

Here is just one method for checking your waste board flatness. this is all assuming that your ends of your Y rails are all equally off your 20x20 extrusion base. fix that first. This is for a warped MDF board.


You can either use these or download the excel files below. There are detailed explanations below also.

This is the way I did it when I rebuilt my machine. It's harder to install the waste board because you do that last, but you will end up with a very square machine.

HOW TO SQUARE YOUR X-CARVE

STEPS PER MM CALCULATOR

Put this in one of the macro fields and no longer drag your bit across the top of the work piece.

G90 G0 X0 Y0;G90 G0 Z0.0

STEP ONE = RAISE THE BIT ABOVE THE CLAMPS OR OBSTACLES!!! (Safety height basically)

Step two = hit the macro number next to the code.

You could also use:

G90 G0 X0 Y0 Z0.15;G90 G0 Z0.0

With the added Z0.15 putting the bit at a safety height of 0.15", but I think it's easy enough to just raise the bit first.

use at your own risk

SAFE(er) RETURN TO ZERO MACRO FOR UGS

(change .505 to your touch plate height).

Here is an excel sheet to help with adjusting your steps per mm:.

and a video of how it looks

These are high quality and identical to the stock collet. They use the same wrench. They don't jam because the nut and insert are locked together.

DOUBLE TAP PROBE MACRO FOR UGS

So do a few passes in a square and set the step over low.

HOW TO CHECK FOR FLATNESS ON YOUR WASTE BOARD

Here is a link to all the grbl settings and what they do.

an explanation of what it all does

M5 = turn spindle off
G17 = work plane coordinates
G20 = inches
G91 = coordinates in relative mode
G38.2 Z = Probe or look for contact for the Z axis
-.5 F2 = .50 inch max seek distance at a feed rate of 2 ipm
G92 Z.505 = coordinate offset Z axis is currently at .505
G91 G0 Z.03 = in relative mode rapid up .03 inches
G91 G38.2 Z = in relative mode Probe or look for contact for the Z axis
-.1 F1 = .10 inch max seek distance at a feed rate of 1 ipm
G92 Z.505 = coordinate offset Z axis is currently at .505
G91 G0 Z.1 = in relative mode rapid up .1 inches
G90 = coordinates in absolute mode

BUMP STOP, G28, AND G30

=(A4*A2)/A6

first find how many steps were sent and divide that by the actual distance traveled and you have your actual steps per mm.

here is a slightly long video from easel showing how to get to the command prompt, what the $ numbers mean, and how to change them. There is also a look at my text file I use to send ALL of my settings to the Arduino with one file from UGS.

Current steps per mm
Distance sent (mm)
Distance traveled (mm)
