Commissioning notes:
- All slide-ways, leadscrews and oiling points oiled with ISO68 Slideway lubricant.
Issues to be resolved:
Electrical
- Entire electronics assembly need enclosing
- Started work on new enclosure. All electronics removed from MDF back panel and in process of being installed in a 19" rack case.
- Cable management
- New steel wire braided flexible control cable acquired
- 3d printed enclosures for stepper motor drive cables design. Awaiting test prints. Will use 19.5 x 19.5 x 1.5 aluminium U channel to protect cables
- 3d printed covers for stepper drive unions designed and some printed. Stepped cover needed a redesign. New cover design to accommodate a cable gland to accept the new control cables designed and awaiting test prints
- All limit switches and stepper cables are unconstrained and unprotected from snagging, - This is now in hand
- A selection of sealed proximity switches have been ordered which will, hopefully, replace the microswitches currently in use.
- 7i76 breakout board enclosure needs a lid - box to be replaced by mounting board on rail inside new enclosure. Mounting brackets are part of the parts we were given with the mill. An ally plate has been marked up but needs cutting to size, drilling and tapping
- Common-ing block needs mounting. Has been addressed using parts which came with the kit
- Parallel cable management. Originally the 25 way parallel interface cable was connected directly to the control board. This would place undue stresses on the board. 25 way IDC D-con parts have been acquired to make up a cable to go from the control board to a bulkhead mount socket.
- Motor power
- add a 13 amp socket to the back of the case and a relay so that the motor can be controlled from the controller
Control Issues
- A touch off probe needs making
- A jog wheel / pendant would be handy
Safety Issues
- Additional Kill Switches
- Full Safety Enclosure with cut-out interlocks on any doors
- new enclosure to be designed in machine building system ally strut with polycarbonate panels to protect users
- interlocks to be added to any opening panels
- need a good solid baseplate. Ideally something like ally tooling plate. How big should it be?
- what is the operational footprint / volume of the mill? How big should the enclosure be?

- Notes
- There's a probe input wired in to a 3.5mm headphone jack on the head of the mill.
- The spindle speed/on/off is not CNC controlled
- Manual control panel
- Electronic Motor Speed Control
- Low Ratio Gearbox Speed Range 100 - 1000 RPM

- Spindle Motor Direction controlled by Forward/Off/Reverse Manual Switch
The spindle speed needs to be ramped up from zero speed. If the direction is enabled with a non-zero speed, the "UNNORMAL" indicator will light and the spindle won't start.
- The motor control has a fault LED marked "UNNORMAL" if this lights stop the machine immediately remove all power and seek assistance!
