You would need to provide this as you are offering different spindles

Yes - the Kress and high speed spindle options come with different mounting hardware. Specifically, within each of the two spindle choices, the collet to bed height as you pointed out has some flexibility in its set-up if required - be it from the tool side, or the work piece side. The high speed spindle position, for example could be adjusted to change this height depending on the work being carried out.

The way I'm reading the Gytis post is that the EXEL machine photo is like a skeleton structure where you can see all the components unlike your own where covers are in place. Your in detail photos were not presented until they were asked for on this forum.

I think JAZZ would agree that we provided timely and comprehensive details when asked (if a bit waffley ey Jazz? )


There is a video of me perched on the machined bed. And subsequently on the Gantry. I''m tipping the scales at over 90kg... 90kG is about 880N. no rude comments please... ... So that is 90kg going through the surface area of my scruffy shoes in the middle of the machine - and then around the machine a bit. I then stood on the gantry in the middle - somewhat precariously.

whats the going weight of a 8 foot by 4 foot sheet of 3/4 ply? over 30kg.. ish?


I also have this vide below if it is of any value here. The UC100 that we offer from CNCdrive motion controls is a nifty little gizmo. I'm sure most of you are aware of / have seen some issues with Mach3 running on windows. Windows put up the road block to the likes of Artsoft that is, they don't let you have control over what the processor does and the PC hardware has to generate the control logic for the drives... The result is potentially poor performance that is nothing to do with the machine but to do with the pulse streams to the machine. Now in fairness to Artsoft, to produce a software package able to be as cross platform compatible as well as they have done is , in my opinion, very very impressive. Mach 3 also is also invaluable in its ability to customize, tinker and add I/O etc. Something the bigger manufacturers just don't do.

The new generation of motion controllers like the UC100 as well as the Smooth stepper, PlanetCNC USB etc etc are allowing industrial CNC control to happen on a desktop PC. The DSP in the controllers generates the pulses to the steppers independent of windows. The communication between the PC and the controller DSP occurs via a USB with the UC100 as examples. In these examples, processor intensive tasks on the control PC can be carried out without compromising the quality of motion of the machine.

The max rapid feed you can get on Mach3 running with a Kernel Speed of 25kHz is a tad over 9,000mm/min? Please correct me? Granted you can increase the kernel speed to increase the feed but you put pressure on the PC hardware. The 15mm/min feed rate shown in the video is there not to demonstrate the the machine can whizzz quickly - its meant to convey the importance of clean pulse streams for reliable machine operation. It is equally necessary for slow movements and for 3D machining where 3,4 and 5 simultaneous pulse streams may be required.

It is also worth noting that you can spec a top of the range W7 64 bit PC packed to the gills with ommph and you'll possibly get better performance out of an old Pentium machine.



if its felt that this is not valuable to the current thread context let me know and I'll move it elsewhere - I did a quick search - if there is a thread where this content would be more suited - let me know.

more details to follow on other machine aspects.
