The CNC Mill was acquire from Wireless Things in 2016 after there close. The machine is quite unique in having a dual Y axis stepper setup however this does require the that startup procedure for homeing is carefully followed
Working area for the mill is 300mm x 300mm x 150mm
Max feed rate is 1900mm/min
The spindle is an Kress 1050 FME with manual speed control from 10,000 to 29,000 RPM
The mill PC is running LinuxCNC with the
Gmocappy is a more friendly skin/interface to LinuxCNC than the default
Axis some people might be more familiar.
More info about Gmocappy can be found here http://www.linuxcnc.org/docs/2.7/html/gui/gmoccapy.html

Due to the gantry Y axis having a dual stepper drive the mill is using a development version of LinuxCNC 2.8, which can currently can cause some issue on start up.
The Y axis is also fitted with two stops, the second of which was designed and add but the hackspace to help in keeping the Y axis homing square to the X axis
Machine start up
Turn on the monitor, PC and Control box
The PC should auto boot into linux and automaticly log in to the
nottinghack account, if not the password is
Once in you should see the following desktop, click on the
Launch CNC icon to start LinuxCNC
Make sure the physical eStop's have been cleared and the eStop light on the control box is out
Reset The linuxCNC soft eStop by clicking the red hand in the top right corner
Turn on the machine by clicking the power button just below
The Interface should look like this
The machine starts-up in
joint mode, in this mode it is possible to move each stepper motor (0,1,2,3) independently but doing so can damage the Y axis
To use the machine we need to be in
world mode where we operate X,Y,Z axis, LinuxCNC automatically switch to world mode once all the joints have been homed, but it is important to only ever use the 'Home all' option as homing a single joint at a time will damage the Y axis.
To open the
Home menu click the icon in the bottom left corner of the interface. (Target and three arrows)
In the bottom menu now click the Home all Icon (far left)
Warning This will cause the machine to move, please make sure all axis are free and clear to move and nothing is in the way for the spindle head
The machine should now be ready to go
Important There should be no need to home the machine again however if you need to (due to axis slip or a crash) please close LinuxCNC first and start again, as homing in
world mode is not supported.
The spindles speed control is manually controlled via the dial on the top.
Power is controlled via LinuxCNC during operation but there is also a slide switch in the side of the spindle, this should be left on at all times
There is a spindle lock button to aid with tool and collet changes
We have the following collets, stored in the draws below the bench
The bed is made form PT25 profile Aluminium at 375mm wide
This give slots ever 25mm for fixing
