Re: Build log of sorts for a 1200 upgrade to CNC
When slaving A to X, I suspect that your problem is that both motors are turning the same direction. One should turn clockwise and the other counter clockwise. You built one CNC router why not build an indexer from scratch with the strength needed for the job. From: "Chainlink" To: "Legacy Ornamental Mills" Sent: Tuesday, July 05, 2011 8:24 PM Subject: Build log of sorts for a 1200 upgrade to CNC I thought that after the chat in the All New Members thread that I would actually attempt to convert my 1200 to CNC, since it may be of great interest to some of the members. On one hand, I hate to reinvent the wheel and try to replicate the work already done by Legacy; I have a certain amount of guilt about this. On the other hand, the CNC upgrade was something like $4000 and is no longer offered by Legacy, so I'm going to modify my machine in the way that I see fit. I'd like to explain where I came from to get to where I am today, ready to make this CNC conversion. I was one of the early adopters of the Carvewright when it was first released to Sears. The machine can do truly amazing work that makes me jump up and down with joy...when it works. The other times, and this usually means as soon as I accept a paid job for some CNC project, the machine breaks down in some obscure way and much swearing ensues, followed by opening my wallet to replace parts. In addition to reliabilty, my machine is not capable of routing a round hole. Most of my work tends to be vector cuts(wooden gears, trophies, etc.), so this lack of precision is disturbing. With this dubious history in mind, I decided to build a second CNC machine from scratch so that I had a reliable backup that was inherently more precise. I decided to build a Rockcliff Model D based on the ease of use of the plans and the cheap to make rail system. One feature of the Rockcliff D is that it has two stepper motors running the X-axis, the A-axis slaved to the X-axis. My machine was built entirely out of MDF and I was quite happy with the accuracy of my work. Everything was working according to plan until the day I hooked up Mach 3 and tested the different axes. During the test, the X-axis and its slave moved in opposite directions, tearing the gantry apart, ruining the entire build. I think the problem was either the type of cable I used(unshielded) to run from the motors or a weak parallel port on my PC (though I don't understand how direction could get messed up like that, it should have been just missed steps). So, there my broken machine sat for a year, $1000+ dollars invested in lead screws, steppers and drivers. Now we have arrived at this summer, and I had a new CNC project to work on, 6 trophies for the YMCA triathlon. I whipped them out on the carvewright and sure enough, it broke down with 2 to carve! I managed to solve the problem and finished the carvings, but I realized something important. Building another 3-axis machine doesn't really help me do anything different from my current capabilities with the Carvewright (when it works). My money and time would better serve me by adding something new to my toolbox, and that is ultimately why I've decided to try to apply CNC to the legacy. -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.

I see you trying to get more people trying to put in their 2 cents worth in the group. And I do think it is a good idea, so let see how many suggestions for projects you can get.

Re: Build log of sorts for a 1200 upgrade to CNC
I have to chuckle because your story is like so many people that have made the trek down cnc lane. It was a good idea but some details got in the way and the parts got put on a shelf but the desire never went away. Look at it this way, your not reinventing the wheel, but perfecting the cnc application on the manual platform. Unfortunately you might find that the platform is the reason the upgrades are no longer offered. Here's an idea for the Legacy, I originally considered a design that used a jackscrew and two racks on the legacy. Simple old school strong design. How are you going to deal with the friction and wear of the delrin bushings? Do you have the z-axis upgrade or will you be taking parts from the rockcliff? Are you going to manually tilt the bed? What's your budget on this project? Let's talks this out and see where it goes. -Tim - Original Message - From: "Chainlink" To: "Legacy Ornamental Mills" Sent: Tuesday, July 05, 2011 6:24 PM Subject: Build log of sorts for a 1200 upgrade to CNC > I thought that after the chat in the All New Members thread that I > would actually attempt to convert my 1200 to CNC, since it may be of > great interest to some of the members. > > On one hand, I hate to reinvent the wheel and try to replicate the > work already done by Legacy; I have a certain amount of guilt about > this.
