Yeah, thats a result of its trying to make a number of nearly equal cuts. I suppose it would be better to offer the user the choice of equal cuts or as specified, with a leftover small cut.

Ill see what I can do.

Ok, the details are mostly worked out and the official announcement is on the HomeShop Machinist web site, see http://bbs.homeshopmachinist.net/showthread.php?t=46691

The short version is that we have made a group purchase deal with Little Machine Shop for 10 of their new high torque mini mills, and with CNCfusion for their ballscrew conversion kits. We also have all the electronics, stepper motors, smoothstepper, gecko540 etc and the Mach3 software.

We have limited it to 10 students, and at least 3 are already signed up. You will get the entire kit of parts, registration at the CNC workshop for all 4 days and all events, for less than the street price of the parts. You will only pay for shipping from the workshop to your home- free if you drive to the workshop and take it home with you.

We will have a formal class each day to work on the machine, then you will have time to attend any of the seminars, or visit the exhibits. By the last day your machine will be running, tested, and ready to make parts.

Brian Barker will lead the day on installing and running Mach, maybe you can get an autograph!.

For all the details see the HomeShop web site. There is reasonable hosing, even dorm rooms.
Its in Ann Arbor Michigan, last week in June.

I agree it is not good to see a total cut more than you requested. Although I don't think it will ever be more than .0001" I will see if that can be fixed without major changes.

I prefer the strategy of making all the cuts the same.
If you want to make a final finish cut you can simply program two operations, the first to rough depth, the second to finish depth.

The wizard does try to make all the cuts about equal. I would not try to make your example of .023 with the last cut as only .003. That would be more of a rubbing action than a real cut.

The number of Z passes is calculated by the line:

Code:
Zpass=  Int(Abs((Top_mat - Depth)/DepthPer)) + 1

I really dont know why the +1 is there- Brian originally wrote that code.I suspect it was to be sure we took at least one cut.

I would not consider the wizard to have errors, just a different view of the best strategy for a cut.
345  Mach Discussion / Works in progress / Re: A lathe screen with buit in wizards on: February 06, 2011, 08:18:23 PM
Yes, my screens work like newfangled in that you can build up a complete part by combining several functions.

I have completely made the code to make bolts, by facing, turning to a  diameter for a couple different sections, then threading, chanfering the end and cutting it off.  All the tool change and offset stuff is handled.

I like the ability to do the functions one at a  time to be sure they are right, then adding them to the program. Of course if you just wanted to use it as a kind of automatic power feed you can do it one step at a time.

The set is mostly done, but Im a bit unhappy with the graphics, they are just plain buttons with no pizzaz But Im NOT an artist so plain is all I can do.

If this set was finished up and sold like the Addon for mill  would it sell?

The width value sets the total width of the array, it is NOT the spacing between holes. You should make width =11
347  Third party software and hardware support forums. / Newfangled Solutions Mach3 Wizards / Re: NFS rectangular hole patern problem on: February 06, 2011, 07:05:21 PM
I dont see whats wrong. You asked for 6 holes, starting at X=1, and made the starting point the upper left corner. That causes the holes to spread out to X3.

Did you expect teh minus value for width to cause the part to be to the left? To do that set the start point as the upper right corner.
348  Mach Discussion / Works in progress / A lathe screew with buit in wizards on: February 06, 2011, 06:59:18 PM
I have been working on a lathe screen set for a while. It is based on the idea of wizards on the main screen set.

Someone posted a link to a Haas LT-1 lathe, and my set does all the same stuff.

The top set of panels is the same on every screen. Down the left edge are buttons to change screens, there is a manual screen and run screen and several wizard like function screens, turn, face, taper, thread cut, bore etc.

On each function screen you fill in the blanks to define your part. There are two buttons, one called 'Do it' will immediaetly do the function you just defines. The 'Post' button will add this function to a complete Gcode file.

It works great for common turning jobs, The thread has a built-in table that lets you select a thread from a list, I have all the normal US threads, 1/4-20, 10-32, 8-32 etc defines, but its just a simple file the user can edit to add his favorite threads.

I hd most of this working at the CNC workshop last June. Ive been kind of ignoring it for a while, but if there seems to be interest I will finish it up and release it as a Newfangled wizard.

I looked at the code. The wizard takes your ode and treats it as a subroutine. Thats why it  must end in M99 which is the subroutine end macro.

The wizard does just generate a series of rapid moves to each location, then runs the sub. You should see an M98 in each move.

Mach does not show the tool path of each sub call, but I think the wizard works correctly.  Try a simple code and see it it actually ruins as expected, dont just look at the path screen.

A wizard should be in C:\Mach3\Addons\[wizard name] In this folder there must be a [wizard name].set file and maybe a folder called Bitmaps that has any graphic files the wizard needs. After the wizard has been run once there will also be a [wizard name].def file that contains the saved values of the wizards DROs


The wizard should have two labels on its first page, one with the content "Author [name] the other should be "Desc [description of the wizard]

These labels are read on start up and build the menu form you see when you choose 'pick a wizard'
