Look at the attached image,
g00 z0 x0 y0 is the F1 key
g00 z-6 x24 y48 is F2
g27 x0 y0 z0 f20 is F3 and so on.
If you want G00 z0 x0 y0 on F1 just make sure its at the top of the list.
To add a new macro type it in the box, select where in the stack of macro's you want it and hit add. It will be the F key corresponding to the order of the list.
To use them just click the MDI box (or select whats in the MDI box) and hit the F key you want and hit enter. Its that easy.

Its in the manual, page 5, clear as mud

Howdy Dylan,
Yes, I use DeskCNC with one of my mill, works near every day for me,
And why not to use when once bought
Many have nothing, even not this, far from other kind of stuff or soft
My question was about acceleration-deceleration, its too sudden when using bit higher speed and cutting brusc angles. I have tried machine setup with not any success, perhaps I have inserted totally wrong figures ...
And faceted surface when curved cut ... is it because DeskCNC does not understand RhinoCam ??? I dont remenber exact what cam I used before, tried many, but before there was not such kind of multifaceted look.
There are many thing I can do bu also many thing where I feel myself totally helplessly because do not understand. With Mach3 I have even more problems
Life is life.
cheers,
herbert
ps:
yesterday made such kind knobs from plastic,
in reality they are not so furry as no the picture
I want to make sure people don't think that I'm
giving DeskCNC a bad rap, I really like the program.
I just would like a good manual so I can use it to it's fullest.
What is the time have for a value under the acceleration profile in the machine velocity tab in machine setup. Is possible to do a print screen and copy into wordpad or paint of the Machine velocity tab and the axis setup tab? It would help to see what values you are using.Howdy Dylan,

hi HCE,
Sorry, I was in workshop for making some parts I need tomorrow morning.
Added photo about some of I milled and about machine conf. setup what I think is random right now because I did not detect any changes when tried to change something ... last time I tried was several years ago
Very misruled?
cheers,
herbert
Well I kept having trouble till I pulled back my max velocity to to 65000 sps. This helped tremendously on consistency. If my machine is warm, clean, and smooth it will handle 84000, but it does not take long cutting for it to get dirty. My acceleration time is .465 and you can hear it accelerate on fast moves. I also left my contouring at 1, 0 would force to decelerate from start velocity on all moves. My take on the contouring is the higher the number the less likely it is to decelerate. Turning my top speed down may be a crutch for other problems, but it works.
Right know your theoretical top speed is 74 mm per sec, dropping to 74000 steps would be 65 mm per sec. Fast transits are cool but not stalling is even better.
If you are stalling I would drop the top speed. If it is just the way it accelerates I would put contouring back to 0 or 1. If the machine does not decelerate the is no reason for it to accelerate. I would say the acceleration scale is plenty as you have almost a full second to hit top speed.
Most important make sure to note all fields before making any changes.
One more thing your start velocity is 7.5 mm per sec so any feed under this there is no acceleration.
hi HCE,
Today was not free time to make changes in velocity tab in machine setup,
Spent all day with urgent works and then one young guy help me with
faceted surface when curved cut. He made some tricks with rhinocam,
Now everything is fine, no faceted surfaces anymore, but NC file for simple
50mm ring with 4mm centre hole is 531 KB , is in normal ?
Made three probes with different spindle speed - 9000, 14000 and 28000 rpm,
Materjal is 8mm 7075, enmill 2mm x 9, two flute carbide.
This young guy is very smart, has touched my cnc stuf just only few months he knows already all, he speaks that all the trick was about curved line continually consists from number of straight lines, but when before was not much these lines then now theses are hundred or thousands time more and every beginning and end of line need to be defined ... oh dear, perhaps somebody can explane these things bit wiserly, may be we are not on the right way at all ... I mean why before was not such kind of problems.
cheers,
PS:
Perhaps someone llikes to see this 531 KB NC fail for 50mm ring,
I have no idea how to show it in this place.

I ordered a lathe, So now I will have a Mill and a Lathe.
Is there an easy way to get Desk CNC to start up in a desired profile?
What did you get for a lathe?
Are you attempting to use the same controller or getting another desk cnc controller for the lathe?
The lathe is just a small Sherline lathe (to match my mill)
I would like to use the same DeskCNC board.
I plan on either "Y"ing the Step and Dir lines (or a switch if must be)
for the X and Y axis lines coming from the DeskCNC board.
I have ordered a second Stepper driver board for the Lathe.
