Help needed on CNC choice
Hey folks I am new to CNC machines so be gentle.
I would like to get a turn key system to do router and plasma work. I was looking at practical but now you guys are scaring me. Who makes a table and controller that someone uses today that they would recomend? Am I going to have to buy the pieces from seperate vendors to get a good machine? If yes then I may see if someone can guide me to the best places to get the parts.
Thanks!

Stay well away from Practical CNC
This is the worst company i have ever dealt with.
I pucrahced and paid in full 7 month's ago and still have not got all the parts in working order.
I purchaced there top of the range machines and it hasent even ran yet.
There unbeatable backup is poor to say the least.
Save yourself the heartake go alsewhere.
Plastic ?????? What???? Parts????

After assembling we started with G28, and the "Z" plunged into the bed. Bad encoder, this damaged the "Z" drive nut by pulling the s.h.c.s. thru the plastic flange. Cut parts for a day when the "X" took off and slammed into the solid stop of the gantry, bending the "X" drive shaft, bad encoder. This time it took a couple days of leaving messages, our frustration set in, we made a new shaft and wedged a plastic shim under the encoder cat five connection and it worked. After replacing parts we managed about forty hours of machining, when the "Z" plunged into the work piece and the servo controller started smoking. The "Z" servo card blew.
After leaving messages for several days, Practical responed with a new servo card and stating they have had problems with servo cards. Machine worked well for a few days when the "Z" plunged into work piece. Stripped "Z" nut! It took two weeks to recieve the part and fifteen minutes to replace. The machine worked for three hours when the "Z" plunged into the worked piece. Hit the e-stop in wincnc and turned off the servo controller. Seconds later, turned on the servo controller and "puff", blew all three servo cards.
After leaving three and four messages a day, five days later, I got through. Sent the controller back, their responce, Practical said the ground shorted due to external power surge or power source. Our machine is isolated from any other equipment or power source. Anyway, to make this long story short, Ive been down four weeks and still waiting for my controller to be returned.

I heard somewhere their response was to put in a bigger fuse.... If the control box fire was not big enough.:confused:
I think IMHO the Z axis plunge is their auto bed material clearing tool. I'm sure you could have solved that with the manual up / down button they have.
I remember them blaming Geckodrive back then about their controller problems when I was having controller problems... I guess Rutex now has problems with their servo drives.
Did you say "Plastic Parts". I thought there was a post stating that Dyna was lying about PCNC plastic parts.
When I owned my PracticalCNC table ( sold it, thank God ), It had PLASTIC PARTS. I guess it depends on which day, which dollar, and which parts they have on the given day in which the moon rises in the SW and follows the rain clouds to the east, depending on the sun on any given day ?????? which parts you get or don't get. But hey, that new table advertisement photo looks great! I just can't figure out why anyone would put that in a regular post instead of the new release products forum.(wrong)
But just my thoughts....:)
