Yet another stepper motor cry for help

[Crevice Reamer]

To use the Keling drivers, you will need a break out board. Which one are you going to use?

What is your power supply Volts and Amps?

CR.

I have the C10 break out board. My power supply is 48 volts 13 amps.

[Crevice Reamer]

Ok. Then the KL6050s are the way to go. At least these are decent drivers and will work reliably. Now you are talking a real controller. At last, I can see you actually getting up and running.

BUT:

C10 costs $26 and requires much potential trouble-causing wiring.

The C10 needs a 5V power supply--offered at Cnc4PC for $26.

The C10 has no charge pump to prevent accidents while computer boots--Offered at CNC4PC for $23.

You will need to buy connectors for cabling. $10-$15.

C10 board offers no opto isolation to protect the computer from damage. This is not offered as upgrade, so you will need to replace the entire C10 at some point.

$180 3x KL5060
$026 C10 BOB
$026 PSU for BOB
$023 Charge Pump
$015 Wiring connectors
-------
$270 total.

Future cost to replace C10: ~$100.

OR:

$289 G540 with Keling $10 discount.
$000 Has built in BOB WITH optoisolation AND charge pump AND logic PSU AND free connectors. AND most wiring is already done internally. AND you have a free extra drive for future 4th Axis capability.
------
$289 Total.

$289 Minus
$270=
------
$019. A whopping $19 savings!! But you DON'T have the mid band resonance dampening that allows better performance and you DON't have 10 microstep to full step wave morphing for high speed rapids. And you will eventually have to replace either the BOB or the computer. And you still have to wire everything up--You can't just plug in the computer cable, connect the motors and PSU and GO!

Now, I know you already HAVE the C10, and you can come up with the logic PSU and are willing to compromise some safety features. I know you are Hell-bent on saving a few dollars. I have given up on changing YOUR mind. This post is for others who maybe can listen to reason.

Its really not about saving money. its about not having the money to spend. The economy here in Michigan is in the toilets. I discovered a little nitch to exploit to feed my family. It must be moved on now before some body else does. I am just a normal working stiff with very limited funds. As previously stated I just need to get up and running as cheaply as possible for now. Very soon however after the first check comes in I start ordering the right parts instead of the cheap ones.

Its not about listing to reason its about reality. The reality of the situation is money, or the lack of. I am selling my own stuff to bank roll this venture while my things are worth a lot to me they are not worth that much to others so I have not gotten as much as I had hoped and I am out of things to sell.

Please dont think for a moment that I do not respect your opinion or even that of springlakecnc. Nothing could be further from the truth. I will follow your advise to the letter at a future time but for now This just needs to get running.

Here is a picture of the 90% completed gantry. Yes I will be grinding down the extra long bolts. I would have to guess the gantry with out the cutting tool on it weighs about 45 to 60 pounds. made all out of 3M and 4M cold rolled mild steel. all parts were cut out on my company's lasers.

[Crevice Reamer]

How's your credit? You could buy everything you need with paypal buyer credit and take months to pay.

For the very REASON that you need to get up and running, you NEED a plug and play solution.

That all-steel gantry looks heavier than 60 pounds. Have you weighed it?

CR.

[aristoi]

LOL Great minds think alike. I had already tried that but unfortunately credit just isn't good enough.

Weighted the parts unassailabled with out nuts, bolts, bearings, and motors. it weighed in at 48 pounds. Most of it is 3m

Hi - just supporting springlakecnc's suggestion to post an RFQ on the forum to get a few brackets made by someone else to get started.

http://cnczone.com/forums/forumdisplay.php?f=74

Who knows, maybe even just PM the people that are helping you out here to see if any of them would make a batch of brackets to help you through this first go. You would be surprised how flexible people will be to help someone - maybe even take payment over time. We are all in this "interesting" economy together.

If the brackets are not too complex, my brother has a manual mill in Toledo, but I am sure you could find someone on this forum to bang out 50 - 100 pretty fast.
