I'm a retired guy with a new PCnC Automation CnC Router running Mach3 and VCarve Pro, looking for a Mentor willing to help teach the basics. I am a Deaf person but lip read and speak very well. I am from Waukesha and wondering if there is anyone willing to help me out. I am a fast learner as I spend 35 years as a Computer Tech for Allen Bradley Company (now Rockwell Automation). I am fantasicated with woodworking and especially the CNC Router and would like to learn the basics to get me off to a good start. ]]> bdsorcic http://www.cnczone.com/forums/showthread.php?t=93866 Newbie X3 Component Weights http://www.cnczone.com/forums/showthread.php?t=93865&goto=newpost Fri, 20 Nov 2009 22:53:03 GMT I took the plunge and purchased a new X3 from... I took the plunge and purchased a new X3 from Harbor Freight and it is arriving next week. There is a fair chance that I may be by myself when it comes to unloading it at my house.

My question is how long should I plan on to take the major components apart out of the crate (head, column, base, table) and what are the weights of each of those items, so I know if it is realistic for me to pack them by myself.

I would also be curious on your thoughts of the best solvent to remove the waxy grease that comes on the components.

Hi,

DXFTool Professional Edition for CorelDRAW is now available. It adds two other export types (Polylines and Polyarcs), tunable conversion settings and more UI options. The Polyarc export type (Polyline with ARC bulges) is THE solution for those applications that say your DXF files are 'not linked'. You will NEVER have to manually link an import again with the DXFTool Professional Edition. Solidworks, Vectric VCarve Pro, Aspire and Cut2D, PlasmaCAM, AutoCAD and many more all benefit from this new technology for CorelDRAW. Current owners of ANY previous version can upgrade for the difference in the price. The DXFTool Professional Edition and all previous versions can install on the same computer without ANY problems so give it a try!

You can get a FREE 30 day / 30 export evaluation copy at http://www.CorelDRAWTools.com - the newest CorelDRAW addon source

I have a cnc'd mini mill with a belt drive spindle.

I'm trying to make precise hole (or as close as possible) to .375" in half inch polycarbonate.

I have a .375 reamer, .374 and a .373

Currently I am trying with the .373 reamer. I have pocketed a thru hole with a diameter of .370". The reamer GCode has a plunge feedrate of 4. When I run the GCode the reamer chatters and squeals its way through and the resultant hole is way way over sized.

I have the reamer as far up into the collet as it will go and I put a dab of oil around the hole before starting to ream. The spindle is running pretty much as fast as it will go.

What am I doing wrong :confused:

Thanks for all help

Jet Edge’s patented Dual Pressure Valve® greatly increases waterjet cutting productivity by allowing waterjet operators to control water pressure independent of the waterjet pump.

With the remotely-mounted Jet Edge Dual Pressure Valve, waterjet operators can run multiple waterjet tables simultaneously at various pressures with a single pump. Operators also can perform waterjet low-pressure piercing operations without waiting for the water jet pump to raise or lower to the desired pressure, saving time and reducing wear and tear on waterjet pump components.

The Jet Edge Dual Pressure Valve will operate with any manufacturer's waterjet pump, cutting head, or waterjet cutting system, and is fully configurable for pressure change ratios. Connection points are standard 60,000 psi-type. The Dual Pressure Valve is pneumatically operated and must be used in conjunction with another normally closed on/off valve or cutting head.

Creative Edge Master Shop, Inc. has greatly increased productivity and reduced maintenance with their Jet Edge Dual Pressure Valve.

I got tired of lugging buckets of ice water and ice back and forth to my Artsign Chinese Laser, so I came up with an easy solution: Use a small cube refer as your chiller!

I found a small "cube" type refrigerator at a pawn shop for $40. (It is the kind with a small freezer compartment inside. It will go way below freezing inside. Most of the small refers on the market now don't use compressors and they will only go to 37 degrees if you are lucky. If you can find the older kind that will work best)

I built a 2X4 frame to hold the laser and accommodate the small fridge underneath. (If the stand or table your laser is on has room underneath, that's even better, but make sure the water source is below the laser)

I then "carefully" drilled a small inspection hole in the upper back wall of the fridge, found the area free of lines, and drilled a hole just large enough for a piece of 1/2" pvc pipe to go thru. I then fed the plug for the aquarium pump and the two cooler lines thru the hole and sealed it with silicone. (to get the plug for the pump thru the pvc pipe you have two choices: cut the plug wire and splice it later, or use a table saw to cut a slit in one side of the pvc pipe so you can spread it "open" enough to get the plug wire inside. You can use anything you want to keep the hoses and wire from being cut by the back sheet metal wall of the fridge, but this worked best for me.)

I also bought an indoor/outdoor thermometer with a wired "outside" sensor and fed the sensor wire thru the pipe and I keep the "outside" sensor in the bucket. I mounted the thermometer on the top of the laser where I can keep a close eye on the temp.

When I'm done, I disconnect the hose from the pump and put that hose and the return line hose in a small empty bucket next to the larger bucket. The lines drain into the empty bucket and it helps to keep the water in the lines from freezing. When I'm ready to use the laser I just open the fridge, plug the hose into the pump, drop the return line into the bucket (which sometimes has a thin layer of ice on top) and away I go. I can easily use the laser 4-5 times longer than just using a water and ice bucket, and the whole project cost around $50. And you can keep a few of those small imitation ice packets on the freezer shelf if you get close to finishing a project and need a few more minutes of cold. Just dump them in the bucket for a few extra degrees of cold time. ]]> firejoe911 http://www.cnczone.com/forums/showthread.php?t=93855 Need A Quote Aluminum Plate Processing http://www.cnczone.com/forums/showthread.php?t=93854&goto=newpost Fri, 20 Nov 2009 19:38:05 GMT Please provide price and availability for the...

Hola, pues eso he construido una mini-maquina de corte por plasma con un plasma hypertherm powermax30 ya que como mucho quiero cortar acero de 6mm y este plasma iría sobrado, la mecánica no me ha supuesto problema, con la electrónica "tampoco" he tenido mucho lio, lo que si que subestime es el uso del control de altura (THC) ya que pensaba que solo seria necesario para cortar piezas grandes y una vez que he probado la maquina me he dado cuenta de que estaba equivocado, en teoría debería mantener una distancia entre la antorcha y el plasma de 1.5mm y no es posible, ya sea porque no hace un buen asiento la plancha, o esta viene doblada de fabrica, etc etc

he estado mirando el MP3000-DTHC de candcnc (sobre todo porque usa 1 puerto paralelo) les he preguntado y creen que si que funcionaria aunque me gustaría tener alguna referencia de alguien con un plasma similar al mio (es decir de poca potencia), dejo algunas fotos y vídeos de las primeras pruebas también agradecería todos los comentarios acerca del corte con plasma

I recently purchased a ZENBOT 1216 for making PCB's and I use the wolfgang spindle for those. (Works great) However when I'm milling other parts I prefer to use a Proxxon.

The spindle mounts on the zenbot are HDPE, and I'm worried that I'm going to ruin the threads if i keep swapping them.
My plan is to replace the HDPE with 6061 Aluminum where the spindle mounts to.

Any tips on milling Aluminum? (to date I've only done plastics, PCB and MDF)

Has anyone with a zenbot have any similar issues and/or alterative solutions?

Thanks
