1st off you never stated what control , you simply said a 1996 vf2. second the control depending on how the drivers are powered may have zero to do with the voltage I asked you to check. why don't...

agreed loose thrust bearings will do that. also check your 12vdc logic voltage to the drivers. 12+ should be 12.25vdc or it can cause an axis to have harmonics while feeding.

I totally agree !! doosan has been in several times. I have asked the owner if he would like me to take a peek at it . but he is dead set that Doosan has to fix it.

I'm not familiar with the msc control. but had a odd similar situation with a yasnac control. ended up there was still some data that was corrupting the memory. they had me do a complete wipe of...

why would you be replacing the linear ways ? in all my years in have only seen a few sets wear out do to lack of oil or grease.

I have a customer with a Doosan lathe that has a 2 to 3 year old machine. they have had issues from the beginning holding +/- .001 on it. they have to run a 3 hr warm up program in a temperature...

go to your diagnostics page. page down to see your DC bus voltage. should be around 340 -350 ish. also check it while the spindle is ramping up.

I'd feel confident if I knew what voltages you had. I'd check them at the power distribution board ( the board that the brakers are on) and yes on the connectors. you can see they are the largest 2...

lol that's the message screen. you can write anything you want on that screen and it remembers it. when it's that way have you tried the jog mode or mdi or any other 1? ok if indeed the power supply...

ok does the machine have probing?

looks like the A axis has a dummy load board on it. does the board have any wires going anywhere else ? not counting the black ,yellow and white going into it .

do believe you could still go back to the atx unit. but I need to see a better picture of all your drivers to see if the +12 and -12 are still being used. or if ur drivers were upgraded to the newer...

u still need to check the voltage when it isn't booting up to make sure a stack board isn't going bad and that's indeed the power supply to be sure. also if you do verify it is the power supply. it...

the 1 on the bottom that isn't being used anymore , was used for the drivers. it isn't a factory power supply. the power supply that's up top is a multi power supply. it creates a +12, -12, +5 vdc...

ok this picture answers everything lol. on the same plate as the probe power supply, is the other power supply. its 1 of the upgraded units. those came out around 2009 ish ?? follow the wires from...

your power supply should be just to the left of the probe power supply. not sure what the hell the 1 in the bottom of the cabinet is. but it isnt factory. my guess is its someone's home made deal...

should be top center and either painted gray or a silver color. its cables go to both the power distribution board, and to the stack on the left. the power distribution board on the right and a tad...

if it were me I'd do the multi screw . in my opinion they do work better than the single 1s.

I know people see a ball bar test is the be all do all test. but I have seen them not tell the whole story. I recently was involved in a fadal that was adjusted , and calibrated by a ball bar. after...

check your voltage from the low voltage power supply. +5 vdc, +12 vdc, -12vdc. it's ATX computer power supply. if you replace it with a computer power supply. it needs to be at least 250 + watt ....

cut a 2 inch round boss and measure across the X axis , and directly in the Y axis. and report back. could be backlash. or you could have bad thrust bearing.

as far as hrs that's about 2 years of 1 shift usage. I have run and serviced all of their models that vintage. only thing I'd check for is squareness of the machine. that will show you if it were...

yes they are not your over the shell vdf. but a custom unit haas developed that they make in house. it's a much higher in both torque and frequency than what is a standard spindle driver. at 1 point...

Haas has a torque chart to prove it. with pulsed DC a 10 hp can produce 2 to 3 times the HP. verses straight AC . it works the same way with the pulse tig welders of today. I have a Miller dynasty...

do you have air going to the A axis brake solenoid? and is the solenoid applying air to the table to release the brake ? sounds like either the table isn't getting the air to release the brake. or...
