The only reason I did not build a DIYLILCNC is because of sourcing the laser cut panels. Here in Australia I could not get a quote under $650 for the work. That was after removing all the text and running the whole job on a single 1200×2400 sheet.

If A kit was available, even from the US, It would have been worth it to just be bale to order it. Most companies around here are not interested in helping people on single jobs, they want contracts, minimum monthly orders etc etc

Mike Beck sells assembled kits of the HobbyCNC setup including Power Supply and cables etc. I havnt used them myself before – Just know of them

By the looks of the pictures he supplies the Pro board in the kit

Just an update, Ive got a hold of CS5 and its working great now. All my conflict issues were because I only had CS3. I have work the next few days so went get time to do anything on them but Im on my way!

Have split them into 7 different metric files and also put all of them on a single 1200 x 2400 sheet as this is what my Laser Cutter has requested to make it easier on them.

Chris; as for your reply

“As to whether you need to adjust the files or not: 6.09mm will actually be a tight fit for material that’s 6mm stock. The best way to figure out if/how you need to adjust is to cut a test joint and see how the parts fit. Hopefully that’s not terribly impractical for you. “

I wasnt thinking very straight when I wrote my first post and stumbled upon the fact that its only 6.09…For some reason I was thinking it was 6.9mm, which would be way oversize, hence I asked. Ive just measured the stock that I am supplying to the Laser Cutter and it varies from 6.05 – 6.12. This variation could be because of my not-so-good quality Calipers.

I feel that if you are in Aus and using 6mm MDF, you dont need to worry about changing the slots. Im still getting a test cut done to make sure.

I will email you the Metric Single files once finished and also the 1200 x 2400 layout if you like. After this gets cut out and put together I may try and convert most of the Bolts, Fastners etc to Metric for you guys. The hardest part (for me in Aus anyway) is getting access to the Pulleys and Belts. All Imperial Hardware, Drill rod, Bearings etc are easily available locally.

I have no other choice but to get Pulleys, Shaft collars and Belts from Mcmaster-Carr, who do not ship to Aus. There is a company here that have a US branch that only deal in imports. They are based in Oregan and will receive the Mcmaster order for you, and then re-ship it out – for a price. Something to think of if you have another person from outside the US looking for these main parts, You could possibly setup something similar if you guys were up for it.

Thanks again,

John

Ive had a look at the clean DXF files but im having trouble scaleing them to metric. When i scale them up the small holes turn into small diamond shapes. In Rhino it seems the circles are made up of 4 parts. Because i need to scale them by 25.4 they dont hold the curve.

I know i can scale the model up in my CAM software, but i need to talk to my laser cutters to see what they can do.

I might search around and see if i can merge the parts of each circle into a continues line. Will try on a copy of CS4 tonight.

Im going to get the laser cutter to do a test piece for me, Just need to get all these files sorted first for them to use them. To keep the cost down I have removed all the text as they want to charge more for that.

Im still not able to edit the files correctly in AI, Im getting an error when I open the file about my version, Could this be causing the problems?

Here is a screenshot of my layers area. I would have thought that there would have been more then 1 layer. It seems that with the version problem everything has merged into 1 layer? I also cant just edit the Symbol, it doesnt show up at all in the symbols area.

My PC isnt that flash and every time I try to open the original layered DXF file in any program it just freezes, Not quite sure why this is. Tried Blender, Rhino, AutoCAD and a few other free programs.

Sorry for all the Questions, Just really looking forward to getting this DIYLILCNC going as it looks great :D

After reading through the documentation I noticed it saying that a little bit of a loose fit is fine.

1/4″ works out to around 6.35mm, and the MDF I get locally is usually bang on 6mm, Should I not worry about changing the slots and just roll with it as is? I could use the Clean .DXF files uploaded from another user in the downloads page. Last time I tried to get a quote with the original layered file they looked at me to fix the problem as they were as lost as I was.

I have had a quick look through the clean DXF files and measured the slots. Most of them are at 6.09mm but there is a few that are at 5.69 which I need to oversize. I think this may have just been a simple error in the converting.

Final Question: Will 6.09mm slot with 6mm MDF be too sloppy for good use? Or wait for greater minds to help me out with the .AI file in the downloads section?

Cheers

John
