Need Help!- Looks like it will be a new CNC Driver for me.

[SpeedsCustom]

So, the whole xylotex system didn't work out too well with my system. I bought a 3-axis system and once we narrowed it down too that being the problem, a 4 axis system was sent too me. Nothing really changed. I used both my c11 and direct xylotex too Pc connection, was using the xylotex numbers that were suggested by EMC2. A new computer was bought that was hitting 15,800 latency.

I don't have the time too tweak things for a few weeks, I need too be up and running in a few days of a new system if I do get something. I have work that comes in and needs too be milled and for personal use, I would love too use the TAIG ALOT more!

I never really figured out what was up with the xylotex system and why it didn't work too well. I even made a resonance damper and nothing helped.






MY goal is too reach rapids on my taig in the 20's-40's. There is no reason why my taig milling machine cannot do such things. Even if it could rapid at 20 IPm, i would be happy. With my current system, the one that cuts and I have been using for about 7 + months... has a max speed of 6 IPM! I rapid at 6!



One thing I did maybe come too realize, if i'm going too spend some money now on some drivers, I want too get some drivers that are not just "ok" but are not the top of the line.

I want too have something with at least 48 volt Powersupply, even if that is overkill, I would rather have more then less.


I have been looking at Keling products, there prices are so nice. Or at least I think they are. People have mentioned the Keling KL-4030, but they can only handle up too 40 VDC and I know that I want too put more volts into these steppers. The Kl-6050 is more of what I'm looking at, but it only has 1/8th and 1/2 stepping, I don't know how this would work and if I needed different stepping, but I feel 1/8th is the best too use for greatest accuracy.


Hopefully I can get some help from you guys and see what you all think.


Mind you, I have the c-11 board already. I would also like too build an electrical enclosure, Keling actually sells and really nice set-up for like 570.00 but I don't need the BOB that comes with it and don't really justify paying the extra hundred few dollars for a box and fan and switches. It only comes with the 48 volt PS too....


Please help.

Jason,

The Gecko G251's would be a awesome choice for your mill.

Are these new Drivers coming out? I do not see them on the site. Are these the Drivers everyone is talking about as of late??

Jason,

Yes, we are patiently waiting on these new drives.

50 volts 3.5 amps and has all the benefits of there higher rated counterparts.

The intro price of $39.00 per G251 is totally awesome.

Uh yea that sounds pretty nice. I just hope they work with my machine and deliver some damn rapids!

I'll be waiting and I would also like too hear from others and there opinions



Thanks Jeff!

Jason,

We have several Taigs and they work awesome with the full size Gecko's.

The Taig is a very popular machine with jewelry designers.

The new Gecko will be a perfect match, you will not believe how well your mill is going to perform.

We have used all the other entry level brands and they do not compare with the Gecko.

What size steppers do you have?

Jeff...

use those if you cant wait for the geckos, cheaper too! they are the ones im running on my x2 and can get rapids above 100ipm, running at 45vdc!! cooool

The 4 axis G540 is only a few weeks away. And should out perform anything else in it's price range.

6 IPM rapids? Thats kinda like Jumbo shrimp. I don't even cut anything at less than 18 IPM on my mill. It's a bit bigger than the Taig though.

My router did pretty good I thought on the Xylotex. That is until I installed my first Gecko's. The difference was night and day. Though I haven't used the little Gecko's yet, I think that is where I would invest. You simply cannot go wrong with those on a small machine. The Keling 48 VDC PS will be perfect for running with the G250's or G251's. It would likely do well with the G540 as well. Motor size and specs might make a difference.

Those drives are very tempting at the price, however I'm leaning towards waiting for the 540's. Gecko's famous support tilts the balance. Also the pool of knowledge about the new Geckos will grow rapidly.

Keep in mind skmetal's machine has ballscrews and is quite different than your Taig. My Xylotex driven ballscrew X2 can hit well over 100 ipm x-y despite 24v and 425oz-in steppers. However this is with the gibs adjusted very carefully and leaning towards the loose side. At these speeds friction becomes the Xylotex's enemy quickly. In interests of reliability the machine is setup to run slower. Fast enough for my needs.

Someone on the Xylotex yahoo page claims to have a Sherline (20 tpi?) running over 100 ipm. Makes you wonder how loose that machine is running

Just so everyone knows, here are my motors Specs: http://www.kelinginc.net/KL23H276-30-8B.pdf Let me know if these are a good choice.


So do I wait for the 251's or the 540's? The 540's are more expensive but of the two, which would really be the best and deliver the most power and speed?

The G540 is just 4 G250's in a case, ready to plug and play.
