Hello Bruno
I am in a fairly similar position, I bought a CC-F1210 with complete enclosure and stand etc, it was installed with NCCAD Professional and a nice little PC included, the machine had run for about 1.5 hours max.. The man selling the machine said his business had taken a different direction, so he wanted to sell the machine, it was about 5 years old but like I say 1.5 hours running.
I had read about the issues with NCCAD so I would not be surprised if I had problems, however to be fair the machine works quite OK with NCCAD. I cut metal with the NCCAD the first day that I had the machine installed, it did not take too lomg to figure out what the post processor should be doing.
Is NCCAD good, well no it feels about 15 years old and is clumsey to use, it has a limited implimentation of DIN 66025 G code but it does work. I just use the KOSY NCCAD to import G code and run/control the machine, I do everything CAD/CAM wise with BobCAD and other CAD programs.
I use the machine every day, I am mostly machining stainless steel detail hinges and feet for composite furniture on a mega expensive yacht, this work is a combination of 2.5D and full 3D surface machining. I get a really good finish once I figured out speeds and feeds for the machine and material.
Anyway to answer your question, I am going to replace the NCCAD system with an Eding controller, I am very familier with Mach 3 and it is very good, however Eding provide their own control software that looks to be very well sorted out, you can download a demo to inspect yourself.
I have a CNC router by CNC-Step and that has a fantastic control made by CNC-Step and with software by Benezen, it is really good but the control is limited to 3.5A per stepper and they are reluctant to sell the control if you dont have one of their machines.
Eding dont sell drives and the like but they told me to go to Hardware CNC which is a Dutch reseller who might be able to provide a complete package.
I think there is some merit in you considering the basic NCCAD equiped machine and then junking the control board, my reason for this is that the Wabeco control is quite well housed and has a pendant type control box which is good. The Wabeco wiring loom looks well implimented with the home switches etc. These parts all take some time and money to get right in a DIY installation.
Are you going with the 1.4Kw or 2Kw spindle? I have the 1.4Kw spindle and it works well, it maintains a constant speed under load. A problem is that the spindle speed is not variable from the NCCAD in the 1.4Kw system. The 1.4Kw motor is an AEG washing machine motor and housed in the Wabeco control box is an AEG board that controls the motor, I have even been able to find the board as a spare part from domestic appliance spares suppliers. I would not let the fact that the motor is from a domestic appliance be a cause for concern as it does a very good job. I am fairly sure I will be able to figure out how to control the speed of the spindle with the Eding control.
What type of work are you intending to do with the Wabeco? I am pleased with mine and I know that when I have upgraded the control I will take another step forwards with capability, I intend to get the option headstock from Wabeco to house a high speed spindle, as I have a spare Jager spindle, this would enable very fine machining to be carried out, I am fairly sure the Wabeco can resolve accurately enough to do that work for me, I am meaning things like 2 part aluminium matched tools for small pressed composite parts (RC propellors around 200mm diameter spring to mind).
I would be interested to know your thoughts on my comments and I will upload some Youtube material for you to look at.
