The controller directly shows the Manual Operation screen.

Hello,
Hope you will be fine. My machine is fitted with heidenhain TNC 155 controller and from last two months it is reacting very strange. when i turn on the machine it do not display the "memory...

Please check your email.

Hi,

When starting spindle by MDI at speed 500 rpm for boring soft jaws. Alarm No 520 appears saying "Spindle start impossible, Check door close, chuck close and center position".

Door close...

fanuc controller 21i_ On VMC servo Alarm No.443 It means Cooling Fan Failure Can some one help to rectify the fault.

i have a heidenhain TNC 145 fitted on BP S2 I2 i can easily transfer 1000 block to the machine but for mold making my shortest program is of 20000 lines. Is there any technique (hardware or software...

I am trying to get the machine parameters of my Bridgeport series 2 interact 2, but i am unable to open the parameter window on CRT. Is there any one who can tell me the standard procedure to get the...

Thanks for help gus.

I am unable to understand your reply gus. I just came to know that i cannot drip feed TNC 145 and it appeared to me very strange i am fond of generating and using thousands (sounds too much) of lines...

Hello Everyone,

I am new to Heidenhain TNC 145 Controller. My question may be very stupid one but, while performing reference return (going to home position ) manually after machine is powered...

What about the power stage of this controller ? if some one is not having a nice industrial servo amp.

Thanks macinetek for your help.

Thanks machinetek for your help. Now i have came across another scheme. I want to make use of existing vari disc (2 Nos.) on spindle and (2 Nos.) on motor shaft with existing toothed belt and control...

Hello machintek,

The spindle bearings will be replaced as per your instructions as i have removed the Aluminum belt bracket and taken out the pulley by press.

After doing...

Hello,

My Spindle was producing a lot of sound. i removed its belt to check whether this loud sound is because of motor or the spindle. The motor is running very smooth after removing the...

Yes i am using BUX48A as well as BUX48B without any trouble.

Matt for the time being i have made the machine to work with an average speed. for X and Z axis my Mach 3 settings are

Steps per = 100
velocity = 100
and
Acceleration = 15.
and my Y axis is...

Hello Kewl_cat,
Now we have finally reached the concluding part of the problem. I changed the Y axis motor wires with the X axis motor wires and the Y axis motor response remained the...

Hello Everybody,

Today i once again tried to find the Y axis fault in my machine. i have decided to replace all the diodes of my machine.
The most important thing that i observed today...

Matt every time there is a new transistor. but only one out of the four is yet not changed.

kewl_cat i have checked all the diodes and they are responding well on the multimeter.
The voltages...

Thanks kewl_cat for your such an experienced advice, but the problem in my case is that the transistor blow as soon as i replace the fuse for y axis. It do not give me any time to play with it for...

Thanks Matt and Dark for advice i reduced the current to 7.2Amps this time and then tried to move the y axis motor but still the same scene happened and one transistor different from the previous one...

Hi HillBilly

I have checked according to your recommendation when the Y SMD board is at its place the current flowing through it is exactly 8.2 Amps and when the SMD board is removed there is no...

Hello,

I finally got x and z axis working fine after transistor replacement :) , but the Y axis after working fine for a few minutes blow a transistor again.
I want to ask you people...

Dear All,
I have found one Y axis transistor with broken insulation sheet from the edge. I hope that it will be the only reason for such a high flow of current. But let me buy and replace a...

George,
I have rotated the P2 potentiometer for Y axis on ACC board to both extremes i.e clockwise and counter clockwise, but the current do not change. I have double checked every transistor...

Thanks timprebleco for such a detailed reply i have followed your instructions and found one transistor blown for all axis. I replaced those transistors and my X and Z axis are now working fine. Y...

Hello everyone,
I powered ON my series 1 today after more than 2 years and found that neither the Z axis nor the Yaxis is working fine, these motors are producing Hummmms and the shafts are...

Hello timprebleco,
Hope you will be fine. Timprebleco, i am facing exactly the same problem as yours. I powered ON my series 1 after more than 2 years and found that neither the Z...

Hello Everyone,

I have a more interesting "GROSS POSITIONING ERROR A" Problem. I switched ON my machine after more than one year of use .When i was referencing the machine axis it...
