Hello; My name is Larry I have a small ranch just west of Angus, TX. I first bought a CNC Router - Plasma 5'x10' back in 2001. I went partners with a guy who said he was an ace at selling products. So we bought the cnc machine I set it up and after working directly with the controller company final got it running great. (wincnc those guys where great to work with) The maker of the machine was worthless. The table was made with quality parts just very bad design. Anyway I got to making parts and had several local welders I was making parts for. Mean while after 8 months my partner had not sold a thing so we shut down. Anyway I had always wanted to build the ultimate cnc machine. One to do wood routing, plasma, lathe, and milling. I have just completed it and I chose to use Mach 3 (which I bought nearly 10 years ago and just let it sit idle) as my control software. After several designs and redsigns i have the ultimate cnc machine. It is 5'X10' table with lathe and milling attached to the end of the table. I have  a 17" Z axis which I can extend if needed. I power the Z axis with a 3 1/2 HP porter cable router which I drive a 10/1 gear box for lathe and drilling. I plan to share with the group here if there is any intrest.  Thanks Crossfire Ranch  Larry

Hi Larry,

Welcome to the forum.

I am sure we could all learn a lot from your adventure into the world of CNC and we would be pleased to see any pictures / descriptions of your build.
If you start a new topic in the "Show'n'tell section" http://www.machsupport.com/forum/index.php/board,27.0.html that would be really great.

Hi all,
My name is Jeremy.  I built a gantry style router/plasma machine with T slot aluminum over the last couple of years.  I finally got it finished, then decided I wanted a laser.  I got an 80 watt Reci laser from lightobject.com.  I have it mounted on the side with mirrors and the cutting head.  I had to remove my Z axis assembly for that.

I am having an issue with Mach 3, and wanted to see if I could get some help.  I was experimenting with loading a G-code file and running it to tweak motor speeds, etc.  I drew up a basic flame outline with netscape, opened the DXF file in CamBam, and generated G-code.  So at first, when I loaded the g-code to mach3, it would show my part in the tool path window, I could run the program, and my machine would move appropriately.  At some point as I was going back and forth between another computer with CamBam and my machine computer with my g-code fle, mach 3 geeked out on me.  When I load the g-code, it does not show anything in the toolpath window, and if I hit run, it starts moving in a wierd swirl pattern.

I have tried going back to CamBam and regenerating the g-code, I tried rebooting the machine computer.  I copied the mill profile and started another profile in case I screwed up a setting, I even uninstalled mach 3 completely and re-installed it.  Each time I get the same results.  It does not show the part in the tool path window like it originally did, and just moves in a random swirl pattern.  

Also, when it was running right, I noticed that my motors did not move as smoothly as they did when I just jog with mach 3.  Actually they were quite jerky.  I have Kelling KL4030 motor drivers, C10 breakout board, and 425 oz in steppers from automationtechnologiesinc.com.  I currently have the drivers set at 1/4 stepping.  I wasn't quite sure which setting to go with.

I would greatly appreciate any help.  I am trying to get a small business of the ground, and just paid for mach 3 and CamBam in the past couple of days.

I'll see if I can post a couple pictures of my machine.

Ok.  Not sure how to post a pic.
Jeremy

Hello All,

My name's Wolfgang and I have had an interest in home CNC for a while. I have previously set up a Sherline Mill with home built controller and DeskCNC software. This was a long but enjoyable process. I recently purchased a Chinese TS3040C Engraver/Router from eBay and am learning how to set this up using Mach3. It is a most enjoyable learning experience. Mach3 is more impressive than I could have imagined and the support forum even more impressive.

I'll look forward to posting questions when I get stuck, and hopefully assist others if I can.

My background is Electronic engineering and I enjoy computer and microcontroller controlled interfacing.

Let you know how I get on.

Regards,

Wolf from Oz

Hi all, Im William. I have been a welder/fabricator for 14 years, my job is also my hobby! Im currently in the middle of building a V8 powered mini (long project!!) I have built up a workshop at home over the last 10 years and love nothing more to be in there making stuff. Last year i got the bug about a CNC plasma cutter, but alas i could not afford it. So then i thought to myself i would try and build a small CNC router machine, to see if i could achieve it. Well, hours on sketchup and google gave me the design i wanted, then at the begining of the year i bought all the componets i needed, made the frame etc etc. Now i am here, having recently purchased a license. I am here because im about to take a very large hammer to my new CNC router!! If someone could point me the right direction to start a project thread, or problem thread i would appreciate it. I have been through what seemed to be every page on here but didnt manage to find an answer ( although it probably is here somewhere) Look forward to hearing from you.

Hi William,

Welcome to the forum.

Just post you problem as a new topic in the General section. It would help if you could give as many details as possible regarding your setup (motors driver type, etc. etc.).

Hi / Bonjour

Here is a bit of myself and the problem I need help for.

I am not a machinist nor an engeneer, I am teaching Kinesiology at University... mainly everything that goes aroung adaptation/readaptation and physical activity. Following this I did start to buiild adapted ski equipment and I trained my student to become instructors in adapted sports ...

I self learn to use solid edge, bought a Small Benford mill CNC already using Mach 2, learn how to use it (with all the mistake you could imagine), bought a press, a metal bender and recently a manual metal lathe (futur project will be to convert it to CNC).

Problems : Recently, I moved and during the transport I do believe that the Mill CNC did not like it  :-\ and I have been trying since last december to fix it. I have changed the breakboard, and switch from Mach2 to the newest Mach3 version.  Did try to transfers all info from Mach 2 to Mach 3 in the ports&pins... but as of now here is what I have been able to do.

I am using a combo Board Rev 5. When I load the mach 3, pwr led gets on as well as led9 which is the charge pump I beleive. Arrow key makes the X,Y and Z axis moving on the screen but the CNC axel are not moving...

This is where I am... and would like a hand to get going

Thanks

Tommy

Hi Tommy - welcome to the forum

Best if you post your question in the general section as more people will read it there. This section is really just for introductions.

Cheers

Ian

I am about sis month into from-scrath 900x950 mm CNC router. Currently using a parallel port 5 axis controler with only 3 axis employed for now. I can only use at about 400 mm/min with only reasonable accuracy. Too slow for guitar building. I have motor tuning to 40 steps/mm  -- 400 mm/min and accelleration of 50. Any faster and I drop too many steps. My understanding is that I may not achieve anything faster with a parallel port system. I am considering upgrade options. Considering the HYCNC-4L vs Smoothe stepper. Would like some input before proceeding further. How much speed would I gain with the USB controller? Do I understand correctly that th Smoothe Stepper is an intermediate interface between my PC and my existing parallel controller? If so would I have any net gain vs. the HYCNC-4L?
Thanks, Tim

Hi Tim,

Welcome to the forum.

Best if you post your question as a new topic in the general section (eg. How do I get more speed ?) this will attract more answers to help resolve your problem.

Fitting a Smooth Stepper (or other external motion controller) is pretty essential if you are using a laptop but it may not automatically give you more speed - there are many factors that need to be taken into account here.
 
Just for example; I get a 100% reliable axis speed of 4500mm/min using the parallel port but because of the improved pulse train and blended feed-rate the 100% reliable speed drops to 4000mm/min when using my Smooth Stepper.

(The Smooth Stepper replaces the PC'c parallel port and takes it's input from the PC via USB or Ethernet (depending on model) and then provides it's output as two separate parallel ports).
