Advice on converting my VMC

**Boyan Silyavski** · 27-09-2016

Ok dokey. Will not say a word more here. Was just being helpful and Objective. Sorry for hijacking the thread. Was feeling the need to say my opinion on subject and respond to accusations or misinterpretation of my words, but just while there was somebody to listen to.

**Chaz** · 27-09-2016

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 ?

**JAZZCNC** · 02-10-2016

Proteus you need to make it easier for us by giving links not just model numbers. We could search etc but then so easy to be looking at wrong stuff then be at cross purposes. Also me personaly I've not got time to sit searching for you.

Looking at what you wrote then If it's the board I'm thinking then your mistaking what the C11 board does.? It's Just Breakout board and does nothing but route signals along with few relays and spindle control. You'll still need motion control card.
The Cslabs IP-S is everything in one package and much higher quality so can't even be compared.

Provide links and I'll gladly look at these for you but I suggest you back off buying anything until you know what your buying.!

**Proteus** · 03-10-2016

My apologies Jazzcnc. I assumed most of you guys knew these steppers and drivers already. My fault.
I do know the difference between the C11 and the CSMIO/IP-S. Just tryed to reduce cost. Besides i was curious about your experience with the DM860A drivers
and 34HS9805 steppers from Longs-Motors vs European or US "made" drivers and steppers.(Link below).
Did take a look at the Hicon Integra as well, but i have already decided on the CSMIO/IP-S. It`s more expencive, but it pays off in the long run.
As for drivers, i have 3 KL-8056D drivers in house and will make use of them. As for steppers, i have chosen 3 KL34H260-35-4A.
These are 3,5Amps 465oz.in steppers and 5,6Amp(peak) drivers. Will choose 2(maybe 3) x 24Vdc/8,3Adc Switch mode PSU to keep noise down.
I do beleive i will have a good system with this choice, but please feel free to comment if you see something wierd :-)

Only using 24V for those drivers/motors looks like throwing away a lot of performance. Taking it up to 68V or so wouldn't cost much more, if you use a linear power supply instead of switch-mode. Linear supplies generally better for stepper power supplies anyway - handle the pulse peak loads much better. Just a thought - you might have already considered this.

**Clive S** · 03-10-2016

Did I read that you are using nema 34 motors if so you might want to use much higher voltage drives like mains voltage. As Neale has point out 24V will not do the job for the steppers.
