Title: Novamill
Post by: Ian Ralston on July 30, 2007, 07:02:18 PM
Just finished the control box on my Denford Novamill, it is 6 x 8 x 10 ins. My advice is to use a box at least twice the size you think you will need!!!
List of contents:-
3 Routout(UK) 2.5 amp stepper drivers.
CNC4PC C11G BOB.
24V 6Amp Power supply.
5V 2.5Amp Power supply.
Spindle motor Contactor.
E-stop relay.
Novolt release starter.
Big fan and filter.

The front panel was engraved with a 1.0 mm cutter using the Mach Write wizard.

Mounted on the back is the SMC-00 DC spindle motor controller from www.beel.ca and an EMC Filter.

The numbers, which are 5mm high, were created in DesignCad using a vector font, exported as a DXF, then imported into Lazycam. I used a small pneumatic impact engraver resiliently mounted, to mark on the 45mm dia stainless steel tube.  DesignCad has a plug-in, ContourCam, which I have yet to play with.

Still learning but the curve IS getting less steep.

 box looks good, what did you engrave it on?

Hood

Edit
 thought I better elaborate, what I mean is what material is it cut into?

Hood,

The engraving laminate was from  http://www.techsoftuk.co.uk the code was TAP-F5 white on black. They are a distributor for Rowmark.

Thanks Ian, now if only they sold similar stuff with Black  on the face and Aluminium underneath I would be delighted. :D

Quite how you get good lettering with this, I can't advise.

Thanks Ian,
 Looks good but maybe on the thin side for what I want. Might be an idea to get some 5mm Alu anodised and see how things work out, I think the local platers may be able to do it for me.

Hi Ian,

Could I ask a question?  I see you're using 2.5A stepper drivers (Routout), I've just got a Novamill minus its electronics so I'm adapting it to Mach3 with new drivers.  I see that the Z axis drive seems to use a NEMA 38 motor, is 2.5A enough to drive this please?

Cheers,

John.

John,

All three axes were Nema 23, so I didn't have any problems. If your steppers are eight lead, you might be able to seriies connect them for a lower drive current.

I am starting work on retrofits of a Novamill and a Novaturn with tool changers. Going to use Gecko G540 and Smooth Steppers on these two. Will post photos once these jobs are finished.

I am very poor at documenting things during work. I'll try my best to document this for all. Here are the photos of machine with existing controls.

Novaturn is complete. Used Smooth Stepper USB and Gecko 540's on it. The steppers are giving 500 mm/min rapids. Initial turning facing trials have been done. Will try threading in a couple of days. I'll post videos of it after trials are complete. For analog FRO and SRO knobs I've used Arduino with modbus. Arduino is also controlling the input from the function buttons installed beside the LCD display. All other I/O's are handled by Smooth Stepper. All the original functions of machine are operational. I'll post more photos and videos of the machine in operation.

you should be able to get 1500 - 2000mm/min rapids on the novaturn and novamill. I would have expected more from that setup.

Thanks Hood for the compliments. The Novamill is complete too. Here is the pic of first engraving test job on it. 800 mm/min rapids on all axes. Original motors with Gecko G250X's and smoothstepper USB. 6 position tool turret, pneumatic vice and pneumatic guard door. All functioning pretty good. Will post pics and vids later.

was the lid control original, or did you add it. It works well.

The lid cover control is original. M38 and M39, according to the original operator's manual. The spindle taper is bt30.
