Thread: Advice on converting my VMC
3 Weeks Ago #21
Clive, don't take that so personally please. That's my opinion and i stand behind it. It comes not from browsing internet but from real life. And even so i have nothing to prove to no one. Just sharing, like you say its DIY site, otherwise for that or other info i charge money most of the time.
cheap PC for garage =old pc= possible near future hard drive fault.
Which by the way is a pain in the a** to prove and find, cause many times sometimes all work, sometimes not.
On the other hand i have been to Asia, know some of them already perfectly, lived there. My wife works in a company and is a head of department and solely responsible for dealing with Chinese production, they have office in China, chinese working for them and she goes like 2 times per year in China.
Right now i am also trying to find the manufacturer and supplier of the other board / the cheap one from the other thread/ . Have already a couple of people engaged there.
So i know perfectly well what i am talking about. [/QUOTE]
Good support? Thats to be proven. What i said was ask for a support before and after you buy from them. Nobody will give you a support if you don't buy from him. You pay that in the price.
But FYI :
I spend a couple of years here in Spain repairing PCs as a side job. Number one fault at least 50% in cases=faulty hard drive
cheap PC for garage =old pc= possible near future hard drive fault.
You missed the pun about the Russians! I do think that your comments about the Chinese etc. are really not acceptable to me and probably others as well.
Cause they are more expensive than the boards could be found
Now this is the Op's thread and we should not hijack it . My opinion is different to your's so I will leave it as is.

This is like comparing apples with oranges. Completely different things.
I've dealt with Chinise for many years both with CNC and other non CNC related business dealings and can tell you with hand on heart I've never been ripped off by one of them. Which can't say to be true by companys in EU.
I can also say I've never had supplier from Uk or EU send me unrelated gifts they are not trying to sell for free. I've had several such gifts from chinese sellers.!! . . . . Infact I'm drinking one of them Now.
Lets just say we are not going to agree on this one.!! . . I won't be replying to anything you post on this matter, I've said what's needed saying so don't waste your time and lets leave the OP thread alone.

Well, at least the OP now knows all the options ...
Seen your email JazzCNC?

Chaz. Choose to look at it with a smile :-)
But in all honesty, a simple questions doesn`t require more than a simple answer

Ok, so far i have to deside on the following options(all being Nema34 With original gearing ration and belted):
X/Y axis Option 1: KL34H260-42-8A Stepper Motor – 465 oz in 6A With KL-8070D Digital Bipolar Stepper Motor Driver-32 bit DSP from Automation Technologies
X/Y axis Option 2: KL34H260-35-4A Stepper Motor - 465 oz/in 3.5A With KL-8056D Digital Bipolar Stepper Motor Driver-32 bit DSP from Automation Technologies
X/Y axis Option 3: 34HS7840 Stepper Motor - 567oz/in 4A With DM860A Stepper motor driver 7.8A 256micsteps 24~80VDC from longsmotor666 (eBay)
Z axis option 1 : KL34H295-43-8A Stepper Motor – 906 oz in 6.1A With KL-8070D Digital Bipolar Stepper Motor Driver-32 bit DSP from Automation Technologies
Z axis option 2 : KL34H260-42-8A Stepper Motor – 465 oz in 6A With With KL-8070D Digital Bipolar Stepper Motor Driver-32 bit DSP from Automation Technologies
Z axis option 3 : 34HS9805-37B2CNC Stepper Motor 880oz-in 2A 8wires With DM860A Stepper motor driver 7.8A 256micsteps 24~80VDC from longsmotor666 (eBay)
A/B 4&5 axis cradle : Belt driven og geared Down Nema 23 465-650 oz/in with KL-8056 or DM860A Drivers that will be decided later.
Controller Option 1 : CSMIO/IP-S 6 axis Ethernet Motion Controller (STEP/DIR)
Controller Option 2 : C11 – R9.6S751-9 6 axis, Multifunction CNC BoB with Relay and Spindle Control
Controller Option 3 : Suggestions ?
Considering the old Nema34 steppers delivered (a stunning ) 212,4oz/in, the new steppers will deliver twice as much for X/Y and even mor for the Z axis.
The new drivers will all be compatible with new controllers and Mach3 or 4, deliver a bit more cirrent, AND will have microstep option.
I have 3 questions i was hoping i could get some quick reply on before i purchase these parts.
1. Will C11 handle 6 (in reality 5) axis at the same time when 3D milling parts on my 4&5th axis cradle considering the BoB itself, and the fact that it utilizes the parallel port?
I mean, the CSMIO/IP-S is NOT cheap(for a good reason) at nearly 5X higher price compared to C11.
However i do want to utilize my ATC in time(which the C11 can`t handle without a PLC). Both will handle my existing DC milling motor and driver
2. Any good reason why i shouldn`t by from longsmotor on eBay instead of Automation Technologies Inc ?
My brief experience with Automation Technologies is very positive, but my impression is that longsmotor seemingly delivers good quality and service. AND somewhat lower price.
3. Should i keep my existing 220VAC/60-18-12VAC tranformer or og for a solution with tripple 24V/8.3A Switching CNC Power Supply, or dual 48VDC/12.5A Switching CNC Power Supply.
Have no idea about the Power output from the existing Torodial PS, but if they did the job when constructing the VMC, it should be able to handle the drivers at max 5 Amps.
That should be 60Vac x 5Amp x 3 drivers = 900W +10% = Approx 1000W. Could try loading it to find max current at axeptable voltage drop, but thta would mean a powerful regulator should be used.
Keeping it at 24V with New PSU means lower noise and should perhaps be considered.
Appreciate swift advice and suggestions gentlemen.
(By the way, old bearly used and functioning electronics and motors will be sold if anybody should be interested).

Sorry about the messy layouts Gents.
Tryed to get some spacing between the paragraphs, and not quite used to this editor yet.
And i came across the HiCon Integra6 axis Controller afterwards.
Any experience With this one anybody ?
