Hello everyone, I thought I would do a bit of a build thread showing my experiences with my new cnc adventure. From looking at other threads on here 90% of everyone seems to be pretty competent, so for the remaining 10% who may be afraid to ask daft questions my build thread may be more applicable to you as I know absolutely nothing, so im learning each day.
I have chosen to buy a mini CNC machine which is 4 Axis and has a bed size of 240 x 340 with a working area of 200 x 400. I paid £420 for this Chinese machine which was actually stored in a warehouse in Germany. The benifit of this was that it arrived in 3 days and zero duty, clever thinking by the seller.
Here is the machine

I had to assemble it slightly in the sense of attaching the motors and plugging them in, simply really.
My mate took the machine to his to see if he could start setting the new pc (purpose bought for this machine) to communicate with the machine, we are using a usb connection and I have purchased Planet CNC software which can be obtained from here:

Whilst my mate was working on the machine it gave me chance to try and make some space at my workshop (which is very small) for the pc and machine. Decided to put it next to my booth
I purchased a cheap workbench from the bay which suits the machine nicely, slowly getting there, will be a nice little workstation once finished

As the control box which came with the machine had a faulty x axis driver I didn't want to exchange it for another cheap one, so I asked a few question on here and got some very good responses, all of which were pretty much above my head. As I have already purchased the Planet CNC software I thought it would make sense to purchase their own control box as I think the support they can provide would be very beneficial to myself being a complete novice. The box arrived on Monday, only ordered it on the Friday so I was very impressed with the delivery time. Once arrived I unpacked it, looked at it a bit confused then managed to find a spare half hour to start assembling it. Work was halted though when I realised my soldering iron was at home.

You would have thought even craptastically weak motors could move an unloaded x axis back and forth.
Seems likely to me that you may have some binding going on. Does it happen on all axis?

Morning Zee,
yes it does mate. I took the motor off the axes and it spins freely, but if you apply your finger to the output shaft it causes it to go mental

That's a bit disappointingly poor! even a little cheap nema 17 on my 3d printer driven from an onboard driver won't do that.
you may need to look at upgrading drivers as well/instead of motors... seems like they aren't giving the motor much juice if they stall that easily.
do you know what drivers you have in there at the mo?
