Good Afternoon Clive

Thanks for the reply. Yes I will keep it ijn my Build log I was going too but I thought I should put it in the right forum section but I prefer to keep it all in the same place.

No I haven't altered the drawings although I know what I want to achieve in my mind. It will essentially be the same design as it was going to be with the SBR Round rails and I did design it for rails to be upgraded later in mind but I couldn't stand the thought of having drilled the holes and then swapping and it just looking so messy.
I did think originally for opting for the 1 motor and pulleys but I just couldn't get the design right because I want to be able to end mill and so I wanted to keep the ends free to clamp too although I have through after I will be able to take the spoil board off and clamp to the frame center section.

It does seem like I'm not on the best path to get everything from Fred So maybe It will be best to get the rails and the Ball-screw and then when i'm further down the road to research individual items.

I will certainly look at the AM882 driver so thank you very much for giving me a starting point to look at.

I still have a long way to go I feel before the Spindle goes in. My excitement gets ahead of me. Are the Am882 best to go for somewhere like cnc4you or are the Chinese versions the same ?

I probably should be looking at the epoxy level before the other items.


thank you

Ok then post some current pics up the the build log and start from there.

One not so obvious consideration is the ballscrews getting bent in shipping. I'm not sure if this is an issue with BST, but ordering everything in one go can help as it makes the package stronger.

Freds is the most well packaged stuff I've ever had from china. For larger orders mine always comes in wooden box. Smaller orders like just couple of ballscrews come in cardboard box like most others but I've not had a bent one yet from Fred.

Hey Guys

Thanks for the replies, I will be going for the pulley option so I will leave those off and get the belt and pulleys after thank you very much for that I would have ordered them without needing them. The wooden Box is always handy too. I have been pricing the cnc4you pricing and Fred is working out at a better price although as said the quality on the spindle has been tested. although it does sound like freds items are of good quality. I think I will take the Drivers off though or ask if he can get them.

I'm really sorry it might be a silly question but for the Drivers to go to 80v I assume that the power supply is the part that defines the amount of power depending on a power output. and would the motor need to be a 80v and above to use this power.

Thank you

Rob

Rob your buying when you don't know what your buying and this is sure fire way to waste money. The fact your asking about Voltage shows you haven't done much research and don't understand how Voltage and motor relate to each other which is very crucial relationship for performance. So how can you buy these items when you don't know what you need.?

Can I suggest you slow down and hang fire on the buying until your know exactly what you need. Fred is great to deal with for rails and ballscrews but there are better cheaper places for drives and spindle etc.

Believe I gave you my Email and phone number so time ago so give me ring if your not sure. If not the ask and I'll give it you.

If you buy blind you will regret it. DONT TRUST suppliers to give you the best components or components which best suit your machine. They will always give you what's best for them first ie: In stock or Old stock.!!
