I started with Mach2, then Mach3,  used Gearotic motion, then Gearotic Thoughts and now Gearotic so I like to think I pretty adept at following your logic by now.    I still have fond memories of getting tangentia l gear shaving to work.

Attached are a DXF of a sample Corel Draw output and the PDF of the drawing.  Corel Draw doesn't like to close curves for one and it generally takes me some cleanup to get it to work with other programs.

I ordered the POKeys and I am sure to be asking plenty of questions I have no doubt.

I've been watching your adventure s for a while now and am pretty close to jumping in, but I have some lingering questions .

The backstory is that I have some older Epilog laser engravers and some parts are just no longer available .  Epilog has been fantastic over the years helping me keep these things running, so I cannot fault them at all.   Also, while hardware wise these are built like tanks, the software is for Windows XP or older and you get the idea.   I have spare laser tubes and just cannot bring myself to abandon these machines quite yet.   They are pretty easy to use for my folks, all they need to do is print from corel draw and it just works.   I've been a bit leery of the homebrew solution in the past.

So, another one quit today and while troublesh ooting I hooked up a Gecko 320 servo controlle r and a copy of Mach3 I had and got it to move around really nicely so am I thinking it's either the servo amps or the motherboa rd, both made from unobtaini um.   This was the push I needed and I am ready to jump in the pool.

It seems to me, that all I need is the POKeys board and I am pretty much all set (I've made several CNC machines, so I know a bit about what I am in for).

My questions .
   The lasers are Synrads and take that "tickle" signal.   I assume that it's not an issue to make that happen?

   I have a set of drawings (pretty much line art and text for trophies and awards) in Corel Draw.  I am thinking I can export them to DXF, then into Vexx and then GCODE for Auggie.   I starting playing around with this and not everythin g is coming over, but I could probably redraw it.    Has anyone tried sheetcam and the laser mode it has? 

   I should also be able to customize Auggie/POKeys to make a pretty simple interface and deal with the on/off of the air assist and making a dial to up/down on the Z axis.   Maybe even reading the pot from the existing control panel?   I don't want to make running these an adventure .

Any big gotcha's with this plan?

It's not a "normal" thread.  It's for a jar so it's kinda rounded.

I have a tormach 1100 with a 4th axis and was trying to wrap my head around how I might cut 53-400 threads in some blocks.   I need to make some fixtures to hold bottles (think of the old idea of nailing mason jar lids to the underside of a shelf to hold jars of screws and such).

I'm sure it's possible, but I have no idea of how to go about it.

I thought I asked this years ago or maybe it's covered in one of the videos but I'll ask it again.

GM had a backlash setting when placing gears, I don't think GT does.   What I don't remember is what I am supposed to do if I want a little bit of slop in my gear train.  If there is a video I need to review just point it out.

You've given me some things to play around with and it looks like it works the way I want.   I've been away from this for too long and am slowing getting used to the gearotic way of thinking again.

There is another gear driving A.   And then a bunch a gears off B that finally get back to C.     Can I place two shafts in the same X,Y coordinat es (different Z) and would that work?   What does linking shafts do?

7  General Category / Support and Bug Reports / Gear Linkage question on: May 20, 2016, 11:05:15 AM

I have four gears on the same shaft.   A,B,C,D    I want A and B to be linked, and C,D to be linked separatel y.   So none are linked to the shaft, but to each other.

I can post my project if that helps.

That's what I am leaning toward.  I have a Tormach and I use their TTS tooling system,  I called and they suggested about the same thing, use one of their blanks and make one.   The blanks are pretty cheap at $19.

Now I remember, I thought the feature was there.  Before I asked I searched on "0" and "teeth" and racked my brain trying to recall.

Thanks Art.

Along the same lines, I need to make a circular disk and would like to use the same spokes as the rest of my project.   I tried setting the number of teeth to zero and really bad things happened.

Is being able to do stuff like this still in the works?
11  General Category / Conventional Gear Cutting forum / Re: Where to get a R8 arbor for involute cutter on: October 13, 2014, 12:08:47 AM
I saw that and I am not sure.  It doesn't look like the other involute gear cutter arbors.
12  General Category / Conventional Gear Cutting forum / Where to get a R8 arbor for involute cutter on: October 12, 2014, 11:40:28 AM
I picked up a set of involute cutters with 7/8 holes.   Looking at the usual sites I'm having trouble finding a arbor for them.   I see 22mm which is close, but not 7/8.

Am I just not seeing them, or looking for the wrong thing.

In my version of the ardunio progammin g package, they were in there several times for different hardware configs, so you might have search and comment out the ones for the hardware you are using.

I just commented out all of them and that worked fine for me.

14  General Category / Support and Bug Reports / Re: Z axis starting point on: September 12, 2014, 01:04:09 PM
Based on Dan's results I thought I would do some more testing with my setup and had some more questions .

I created a 25 tooth gear, DP 20.06 and Module 1.27.

The gear is listed on the Project screen as having 1.3457 Diameter
On the G-code Processin g screen picture the stock width is listed at 1.3423, the height is 1.3447
On the G-code Processin g menu, the material size is X 1.3776 and Y 1.3801.

I've always made the blanks the stock width or 1.3423 (at least I think I have).  But since I zero at the top of the stock, I see how this can be very critical.   Am I using the right number?   Why not make the Z the centerlin e of the A Axis instead of the top of the stock.   Maybe we could also have a function that trims the stock to the right diameter?

That way I get my stock close, and the mill does all the rest.
15  General Category / Support and Bug Reports / Re: Z axis starting point on: September 08, 2014, 04:20:18 PM
Or send us a picture of your setup and your config screen.  I cut A-Axis gears all the time and have had great results.   Using a probe tool to get the exact offsets has been a life saver for me.
