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...

Re: Tool offset issue

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

Re: Micromill is going to kill me!

Hi. When you say you are struggling to go online. Does the computer find the machine and download the flash? Or does it come up with the message to check the power and USB connection. If this is the case it sounds like the machine is communicating but it may be an issue with the ratio. Can you detai...

Re: spindle causing steppers to jog

No turning it down is better. if the motor over speeds it sparks creating noise.

If max RPM is not too much of an issue you may be better setting it at 2800RPM

Re: spindle causing steppers to jog

Hi If the spindle is running over speed by too much turning down the pot will will correct the RPM but as a lower voltage is creating the same top speed the current into the motor will increase. Various things can cause demagnetization. Over current, repeated stalling, over voltage and running over ...

Re: spindle causing steppers to jog

Ben, It does sound like an electrical noise issue. The spindle motor does not have an encoder fitted so the speed it's actually doing is set by the voltage. When the machines are tested the drive is tuned using an external tachometer to set the top speed. Do you have any way to check what the machin...

Re: Setting boring bar tool offset.

Either set up the tool on an internal bore if you can or the simple way is to set it at the outside diameter of the bar and set it there. Then fine tune by boring a diameter then in the offset window click on the vernier symbol and enter the programmed and measured diameters so it corrects automatic...

Hi, The problem is that the software only sees lines intersecting the center line as a parting cut. Your problem is that your parting tool would crash into the component if its larger than 30mm diameter. The simple solution is to just draw it as though it it could part off then edit the part off lin...
