Maho (Phillips432) graphics help please?

[smoregrava]

The alarm means you have not started the hydraulics. If you read this thread I had some problems with the start up sequense. I had to change two wires of my 3 phase intake. And then the hydraulic stayed on

Star up sequense:
" Hydraulic Button" ,"Hydraulic button" ,"AND "Clear button" and "Hold" the "clear button and hydraulics " until the machine starts all within 5-10 seconds or it will not start.

I never turn on this machine. Are you saying that i must press the button next to emergency button twice and then clear button and then clear button and start button at same time?
I see that this machine it's very complicated to turn on .
I will tried to do this.
Thanks to all.
Regards

Yes the button next to the emergency is the Hyrdaulic button. Yes the startup is quite uniqe. But when you fist have done it its no problem. My manual state something that the machine checks the emergency system so the machine always has to be started up twice.

The time between first and second activation of the Hydralic button should not be more than 5- 10 seconds.

Yesterday my Maho 432 to talked to my computer(DNC)for the first time. I have made a DB9 to DB25 full handshake cable (Like in the picture). And i used Hypertermial to transfere the programs. easy and seems to work nice

Here is how I did it if anyone wants to know:

First I checked Machine constants
Nr 115 =1 means 2 as stop bit (=0 means 1 is stop bit)
Nr 116 Input Baudrate and
Nr 117 output baudrate. In my case baudrate was set to 300, but I found in some papers that they had used 4800 before on my machine so I will change this as soon as possible.

Then I opened Hyperterminal (Is in windows under comunication)

I used this parameters
connect to Com1
Baudrate= 300
Data bits= 7
Parity= Equal
stop bits= 2
Flow controll Hardware

Send CR at line end
Local ecco

Then I go to the controll and press
"MANUAL"
"PART PROG"
I selected ALL MEMORY
press "MEM LOCK"
"DATA INPUT"

Then I used a simple program as a test

% PM
N9008
N1 G1 X20 F500
N2 G1 Y20
N3 M30


I marked the text/program above and rigth click in Hyper terminal window and choose "Paste to Host"

When all lines was sent I have to press
"CTRL+D" on the computer. Then the program is in the controll.
I Actually don't anderstand why I have to press ctrl+D. But is works

I also loaded programs and tool table out of the machine to the computer.

Hi,

Remember, when you are starting machine,if you see sth in front of coordinates, press the Hydraulic bottom until the writtings are cleared then simultaneously push hold bottom.

Can you run the machine whit drip feed?

[smoregrava]

No I have not been able to drip feed. It seems my controller is to old. My mahcine parameters only goes up to 214. I have done some testing and my controll can take something like 2400 lines. I have tested some 3D milling at it works But programs easely get bigger than 2400 lines.

A nice thing is at its possible to load a new program while another program is running.

I have done some testing will try to post some pictures of som engraving I have done. And I made some really simple but usefull programs as standard progams that lies on my computer and just download when needed. like pockets. drilling circular pattern and so on.

[smoregrava]

Some small tests. Here is two examples of some tests I did. The maho cycles picture is just testing some of the internal cycles in the 432 controll. The other is a small engraving done from a DXF in Edgecam with my home made postprocessor.
The material is EBABLOCK a very nice material to machine.

Unfortunally I have been strugeling with my machine (Mh 500C 432) tonigth. When I transfere programs the last 5 lines of the program is not transfered and the controll do not respond. Have to type inn the last lines. Very strange. I have been trying some different Machine constants so I will try to change everything back. But It would be very usefull if anyone had a full description of the Constants. I have a german version but many constants has no names or notes.

I had this problem ages ago and am trying to remember how to fix problem. I think you need to have a Control-D sent at the ned of your program. You can type it in yourself at the sending PC or have your post processor add it onto the end.
Originally I used to simply add a whole heap of carriage return key strokes (end of line arrows) more in number than the max number of lines you are losing say about 10 extra lines with noting in them... this was until I found Control-D did the trick.

Norway is a long way from Australia ! we are all upside down here but Maho still work OK if you bolt it to the floor tightly it will not drop off the globe!

[smoregrava]

Thanks VWSatOz

I filled in some empty lines at the end. And then I could edit in the M30 at the end. But it's very strange it did not do this before. seems like when the controll discover the M30 it just stops reciving so it does not recive the control +D eigther when I type it in. and this have worked nice before. So the only way I figured out to make the controller respond is to press auto. Then the control come out of the Data in mode. But if I try to send a new program it won't recive anything. So I have to restart the machine to make it recive anything??

I still belive it could be something with my constants. I know I have tried som different values on the C114 But I'm not shure what it is.

I checked my constant list. and many of my constants has a (*) after (see picture). What does this mean? constants 112,113,114,115,116,117,153,154,158,159,163,164,168,169,195,196 is marked this way.

Anyone know how to send all the constants out. I manage to send all programs,macros and tool offset list but don't know how to send the constants

Here we do not need to bolt the maho to the floor. But the fingers can be really cold :-)
