hello

i have lost my parameters of my cnc BIESSE rover 336.
It's a RT480 controller and this morning when i started my machine all the data were deleted.

my floppy backup doesn't work it write that the floopy is empty !

i need your help please if someone use this kind of machine.

i work alone in wood manufacturing and no cnc is a disaster...

thanks a lot and sorry for my french english

[battwell]

you will need to change the battery before backing up (inside conroller, bolted to side, looks like a bomb with curly wires. 5ah 4volt cyclon cell)

hello,

i tried to contact biesse fr but there are all in holiday ...


i wil try to change the batterie but i need to find a backuo of my data system and i dont know if biesse wil be able to do that and how much does it cost.

tks

[battwell]

did you only take one backup of data?
are there any disks inside cabinet door flap?
biesse uk are very good as long as your spending money
however, if you have lost your tooling data etc this has to be all re entered by hand.
your about the 6th person this year to lose all data

[freezengate]

yes i just made only one copy of floppy backup. and the disk seems to be empty...

i will look inside the controller like you said.

i wil try to contact biesse uk because in france they are always in holiday...

i just hope that biesse have a copy of my all data machine, nevermind if i have to re entered by hand.

best regards

[battwell]

you may, hopefully , be lucky after changing battery that the disk may read correctly. control doesnt seem to like doing anything when battery is flat!
(im converting a 335 here due to naff control after a flat battery with no disks available)

when you get it going again.
make backups as follows.
make sure floppy is fresh formatted in control at 1440kb
make backup. ensure at end before removing you dont have any op code showing on screen. (denotes a non copy fault)

you need to make backups of programs (c)
fixed cycles and data (D)
all data (C)

keep these in a plastic bag inside control box
make these every month religiously!

its too expensive to have a biesse tech for a day to do a re install (and it usually drags out longer)

[freezengate]

i will try today to look after the battery.

i still havn't news about biesse fr...

its sure that if i success to repair the cnc, i will make backup correctly and like you say every month.

for the moment i m stopped.

best regards

[battwell]

any luck?

[freezengate]

no reply from biesse france...

Hi
i post here to explain how difficult it is to resolve from data lost.

Finaly a tehcnicien from biesse come to see the cnc.

biesse doesn't have a copy for my machine but standard data from all Rover 336.

so we started by refill all data to the cnc it inclued :

data machine
plc
cycles fixes (G1, G2...).
language


After first restart we saw that :

speed avance parameter of axis were not correct.
origines machines and butees too.
Tools changers freez the cnc

a couple of hours after the cn was able to work but not like before...


Now i have 2 pb that i did'nt resolved :

The cnc make a big "kick" ("accoue" en francais) in each point of move.
i mean that in each deplacement to a specfific point like X200 Y200 Z20 the cnc go and stop to it with a big kick. and if you have 8000 lignes de code i let you imagine the consequences.

Second point a pb occure during the drilling when i do 2,5D. there is a lot of deplacement with a precision of 0,1mm and at one moment the cnc freez.
error S3027 (machine was not able to send command to controller. Certainly due to too much point.
So i need to drill at 5% and for the simplest things i have to wait 30min....


so if someone knows these pb and could help me it would be great.

thanks a lot

[battwell]

the axis acceleration is too high!
maximum it should be set to is 2000 for x and y
1000 for z axis

set under axis data.
you will find everything runs much smoother if you half those amounts.
keep x and y acceleration the same! or diagonal lines wont be spot on.

also set max axis speed to 40m/min for x and y
max z 10m/min

that should sort out your troubles

[battwell]

when you have done that set your homing origin using a drill not a router
test drill at x50 y50 and measure. adjust homing until spot on (drills are at a fixed position on the head)

then try a test cut with router at say x100 y50 to x200 y50 to align router in y axis
then do the same sort of thing for x axis


this way you can re align everthing properly

[freezengate]

yes batt you are right.

i have set my origin with a drill and its ok now.

i put the speed very slow like 2M/min, the acceleration ratio very slow too. but the pb is always present, the cn give kick.

i put G47 code to disable the precision positioning and the pb is reduced but still here.

I don't know why this happen ? maybe i have to modify other data machine.

the cnc freez when i make 2,5D and i don't know what to do. when the cnc freez my piece of wood is not usable because the head make a little movement on x and y and drill away the target.

[battwell]

did you set both acceleration ratios in each axes data?
i think there are 2.
have you checked encoder count setting is correct? should be 500 count encoders? maybe 2000.
is it 481 control or 480? i can check settings in manual for you.
did biesse tech not know what to do?

[freezengate]

biesse doesn't know what to do know...

i have to check if i have both acceleration ratio, i don't know.
we have already change the value with the technicien because we have seen that : when the cn move 10mm in manual in réality the mouvement was 40mm.

but we don't know the exact value, we have made a lot of test and we found a value near the reality with a similare cnc rover (i don't remember the exact model i will ask the technicien).

i will tell you tomorow what value we put. my controller is a rt480.

what do you think about my freez pbn have youy ever seen this kind of pb ?

[battwell]

the encoder counts are quadrature . (seen 4 times )so your amount should be either 2000 or 500. check what is written in your control now and swap it.
)that is why your getting 40mm instead of 10mm
probably why everything is jumping as its trying to move 4 times faster!

[battwell]

also your steps per unit maybe incorrect if your not getting exact distances.
i presume you have 20mm travel ballscrew on y, rack/pinion on x and 5mm pitch screw on z axis?

i can send these values if you cant work out exact

[freezengate]

here are the data machine from my cnc and modified by the biesse technicien :

first number is X
second is Y

what do you think about this ?

[battwell]

i just went to workshop, got generator stareted and found my data as follows
you owe me a gallon of diesel!

first number is X
second is Y
third is z

if all else fails... my new controllers are almost ready for sale!
see this to see what it can do now!
