CNC files

Hi folks This site is dedicated to the machine Maho MH500 C with the controller Maho/Phillips 432

Sorry folks my spelling is terrible but I hope you understand some of the things here

To get the moust out of this CNC mill you need to connect to a computer. Then you need a Serie RS232 cable

DNC from Computer to 432 controll

Here is the instruction on how you transfere programs beteen computer and the 432 Controll
I made my Maho 432 to talked to my computer(DNC). I have made a DB9 to DB25 full handshake cable (Like in the picture above). 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= 2400 Input Baudrate and
Nr 117 =2400 output baudrate. In my case baudrate is set to 2400, but I found in some papers that they had used 4800 before on my machine so I migth try this.

Then I opened Hyperterminal (Is in windows under programs/accessories/comunication)

I used this parameters
connect to Com1
Baudrate= 2400
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 its works :-)

Remember to press "file" and "save as" and save the hyperterminal settings on you desktop.

Here is a little logo milled in my machine. The pocket was done with program 9003 (example under) an the G code was downloaded to the machine with Hypertermial

I have done some programs examples here and written a litle note. These program can very easily be modified and then used again and again.

I have collected some documents that can be usefull when you work with a maho 432 controll

I have made a post processor for Edgecam. The post is buildt up the way so it exchanges the Z and Y axis and invert X axis. This means that when you se the modell in edgecam in top wiev you will see the part the same way as you stand and look down on your part. So when you are in edgecam everything acts normal. And the simulation will do the same as the machine.

The post might have errors and I have only done some testing on this. You use this post at your own risk. If you find errors please sendme a mail.Have done some bug fix and the new version 18 is way better.
