Re: Releasing Tool With No Compressed Air

Hi. The compressed air is only for toolchanging. If you don’t want to use that most nova mills were fitted with the easy change Toolholders. This limits the travel available but does let you set tool offsets.

Re: Triac PC Emergency Stop

I would guess you could. Copy the schematics for other machines. The feed and speed overrides wire in the same place on all machines. 10k lin pot.

Re: Tool offset issue

Make sure the gap between the switch and the bolt it switches again is as small as possible.

Just keep homing it up with a clock on the axes and this should resolve it.

Re: Tool offset issue

Sending the machine home with the XYZ button makes it find the Home switches. On the Novamill these are proximity detectors. As it is finding a different location when you send it home I would check the switch is secure and the surface it registers when it Home’s is also clean and secure. Normally t...

Re: Triac spindle stalled, now won't start!

I would doubt there is an issue with the motor. At lower RPM you have lower torque which could cause a stall. does the stall occur when plunging or cutting? feeding in at an angle may help. I would select Manual Mode set your spindle to 800 rpm and then set the feed to around 100mm/min turn down the...

Re: Resolving No Firmware & No RS232 Connection

Some of the earlier RS232 internal cables had fewer connections and were not able to upgrade firmware I dont think they had the CTS and RTS wires connected.

This could possibly have been the issue.

Re: USB Upgrade Procedure

The Green display indicates you have a NS card (NextStep) which is the version supplied just before USB. The capability for 3D interpolation is just as good as the USB card. I would initially try getting an RS232 to USB adapter and see if you can get that working. VR Milling 5 will work with the car...

8 Bar is fine and we use the Bambi at Denford.

I would set the pressure at 80psi.

Re: Triac spindle stalled, now won't start!

I would agree with Martin the spindle fuse should be a 10A F rated fuse. If you don't have this you could cause damage if you stall the spindle motor the slow blow will not act fast enough to prevent this. There is also a thyristor fuse on the spindle drive itself that will blow if you really crash ...

Re: V3 not working since upgrade

Hi, It would be very unlikely for the rectifiers to be the problem. Most likely one of the stepper driver chips. Have you done anything with the machine itself? To damage a chip it would take a short circuit from one of the motor wires to ground. Check the 3 L297 and L298 chips for damage. These dri...

Re: Lead screws on microturn?

The unit has lead screws but the pitch is very fine.

The machine body is made by sherline which should give you some idea of its suitability.

Re: Tool offset issue

In 96 it would have been DOS software. If you check the serial number label on the cabinet it should say what software was supplied with it. The issue you mention with subsequent tools running out is this in the X or Y axes or the Z If the Z then I suspect offsets. If X or Y I would check the machin...

Re: MRC40 and DP50 setup

Hi,

The hose should go through the hole in the sidewall then the spring clip on the back wall and into the bracket by the spindle.

The hole around the hose is normal as it will allow air into the cabinet.

The vac is designed to remove airborne dust and create a negative pressure inside the cabinet.

Re: Denford cyclone TU150E Threading problem

What happens when you program 300 rpm and try and cut the thread? Does it just hang up in program or do you get a message on screen?
If so can you post another photo showing the program and the message?

How did you create the program? What package?

Re: Not stopping and homing after a job

How are you stopping the spindle at the end? Can you just enter jog mode?

It could be the communications have failed down the USB. What are you machining and are you running the extraction?

Is so try running without the extraction. It could be a static problem.

What speed are you asking for in the program when threading?

I would suggest 300 to 400 RPM
