Machine Down!!

[dougie8]

Hi m_c

Thanks for replying to my post, after some research I think you are correct the DCM pin looks to have been connected to pin 14. I found the following video on Youtube

I have also linked a copy of the user manual for the VFD, if you get a chance could you confirm?

I've had a look at the UC400, this looks to be an ideal solution and also future proofs the machine, do you have any recommendations on breakout boards and PSU's I've had a look and theres quite a lot to choose from? CNCDrives BOB's don't really explain the connections very well, I'm also not sure how the VFD connects to their BOB's? I can't seem to see PSU's for sale on CNCDrive?

Thanks again.

Regards
Dougie

I'd double check with a multimeter, but I'm pretty sure the DCM should go to 0V (it's been a while since I've had to wire up a VFD!). Hopefully somebody else will confirm.

BOB wise, I'd guess the usual cheap generic 5-axis Chinese ones available on eBay is as good as any for a basic machine, as they include the needed circuitry to get a 0-10V analogue output for speed control. I'm not entirely sure if there is any difference between the green and blue ones...

PSU wise, I personally prefer DIN rail mounted supplies, but there are lots of options. I'd think you'll only need a 12V supply, as the UC400 takes 12-24V, and everything on the basic BOBs uses 12V (plus I think you need 5V via the USB for powering the step/dir outputs).

Typically, S1 and DCM would go to a relay, with the relay closing the circuit between them.


Not sure what they were doing with S3-S5?

My recommendation would be the UC300ETH with a UB-1 breakout board from CNC Room, but it's not cheap. Very easy to wire up, though.

Hi all,

First of all thanks to all who have replied to my post your help is greatly appreciated.

I am about to order the UC400ETH along with the UCCNC software, however as I will also need to upgrade the breakout board I have found this to be a bit of a headache due to the options available. I have found the following three all on various websites can anyone recommend a BOB that will be compatible, and what the difference is between a £10 board to a £50 board?

CNCDrive

CNC4You

eBay

I have also found on Stoney CNC using the HDBB2 board (see attached), as they are UK based presumably they would arrive before Christmas, Ideally I would like to get the machine up and running again during the holidays.

Thanks again
Dougie

The UCBB board will NOT work with the UC400ETH. It also doesn't have analog speed control, which you probably need for the spindle.

A $10 breakout board is the cheapest you can get from China.
In some cases, a $50 breakout board is the same board, but imported, sold and supported by a reseller.
In other cases, it will have more features.

Hi all,

Thanks for everyones previous replies, I never managed to get my router upgraded as per my previous posts as I managed to grab a hold of an old XP pc which got me up and running again with NCStudio.

Sadly this has now given up the ghost (I think the dampness in my garage is killing the pc's) and I'm now back to where I was before Christmas with a router that is now not working. I have been saving up my pennies for this day to come and have now decided its time to bite the bullet.

I have spotted the following on CNCDrive which is on special offer with a UCCNC licence included:

Can someone advise if this would be suitable for my machine?

I have a spare Windows 10 pc lying around which has not too bad a spec, other than a new PSU for the controller, what would I require to get my machine back up and running?

Has anyone any knowledge of this controller, is it fairly easy to setup and get running?

If anyone has any other suggestions I am open to ideas, obviously price dependant.

Thanks again

I have the UC300 eth from them and find it very good. It was easy to set up for me as a novice in CNC.

I had a PC disaster immediately after getting my second hand machine, lost all software and settings. That is when I decided to go with an ethernet motion controller. Uccnc works on a low spec pc very well for me.
Those new contollers with built in BOB look like a neat solution, seems like a bargain with free software licence. Similar idea to this one https://www.cncroom.com/interface-ca...igo249ia6r2v25
but much cheaper.
Just looked at the PDF http://www.cncdrive.com/downloads/AXBB_E_manual.pdf and it looks like the same setup as the uc300.

Good luck

Ollie
