I am looking a getting my first cnc machine I have a few different options so far. I plan on using it for guitar making.
CNC Shark Pro Plus.
*Big enough to do an Arch-top or Jumbo Acoustic Guitar.
Very Expensive in Australia $5995 without postage is a massive rip off. If I am going to pay that much I might as well import a Romaxx.
*Still big enough to do an Arch-top or Jumbo Acoustic Guitar.
*Roughly 1/3 of the price of the Shark and that includes shipping from the states to Australia with import duties.
Cons. The HDPE Construction worries me. Will it be Rigid Enough?
*not big enough to do an arch-top or Jumbo Acoustic Guitar other guitars will be ok I can still use my other tools when I make these bigger guitars.
*from what I read the controller box isn't that crash hot some have found the controllers were not grounded properly if at all.
This forum doesnt get the most interest unfortunatly, i was in the same position as you wanting to make guitars, i am in the process of finishing my 4x6 router, anyway any cnc machine with the routing area will make a guitar, the rigidity means on how fast it can get the job done, an MDF machine will do it, it just means you cant push it as fast as say a full aluminium machine, have you had a look at the Joes2006 2x4, i know its MDF but its probly a good starting point and will make guitars, it is rigid enough.
anyway if you making guitars would love to see some of the designs you come up with
Its hard to tell, comparing a BASIC aluminium to a BASIC MDF, with out seeing both models, on a machine that size i could be safe in saying you would only be running nema 23 motors not 34s, so there going to be your limiting factor anyway not the strenght of the machine, on both machines with equal motors the alumium one could probly be run a tad faster, but in saying that it would mean on a guitar taking 4-5 (give or take) hours to carve front and back, the alumium one might be 10-15minutes faster over all. which is nothing over a few hours, but with the alumium one costing a few thousand more i wouldnt bother
Which zenbot you lookin at? is it the 24x24? if so it looks expensive for what it is and only have a cutting area of 24x24. i dont represent joes cncs what so ever but looking at bang for buck, at least with a joes cnc 24x48 you could do neck and body all in one designs, anyway it comes down to space to, i would go the gecko controllers, they seem to be the flavor round here
His plans are free and there are a full set of 3d plans that you can view in the easm E-Viewer, and that should give you an idea, but apart from the MDF kit from joe its the motors and bits and pieces, but there is a whole forum with hundreds of build in the diy cnc router forum under the wood work section
