I will be back at work Sunday 21st October. I will see what I can find in our manuals. If there is nothing there I may be able to help but I'd need to know what you have already tried. I will also ask about DNC.

Hello Guys,
Back a month or so ago I upgraded a 700c from level 311 software to 600.
A fellow board member was kind enough to give me a programing manual, but it does not have any info on how to use the graphics.
Can you please help with graphics operation,would you be willing to copy or scan this section of your manual please?
Also is anyone using DNC to this control, if so what software are you using?
Please contact me to make arrangements sentnermts@netscape.com.
Thanks for your help.
Regards
DD

Hi Deckeldoctor
Maho 432 control is very old I did run DNC using Heidenhain Tnc data transfer software from Heidenhain and it run on Dos I dont know if you still can use it on today win sp or vista.
I have used serial interface from Cadds5, ages ago though & 2d downloads form EzCam (not DNC though). Maho 432 has 3 buffer zones in the memory for DNC trickle, one in use, one being filled ready to go, one being dumped. You can set the amount of memory reqd. doesnt need much. I never used the graphics. I would rather do it all offline on computer CAM software & verify somehow then send to machine memory or trickle feed for 3d stuff.
Hello Guys
Thank you for the replies, a fellow board member has copied the manual for the graphics help.
I have been able to send programs to and from the machine using rs232 no problems.
My customer is now using the machine to its full capability and is now generating long programs from the cad/cam system and I would like to get the Drip feeding to work.
Regards

The maho manual should tell you how to get drip feeding to work, a lot of button pressing sequence to go through on the Maho keyboard to prepare the mc b4 "go". It's ages since I had need to do it & would would have to dig up the procedure. If no one else helps or you get stuck I will try & find the method I used.
Hi I see that this is an old thread but I have just bougth a maho mh 500 c. with 432 controll on it. I belived that there was no dripfeed options on this controll. Is there different versions of the 432 controll?
what is the memroy of the 432 controll 256 kb ??
Best Regards Arild Brudeli
My Maho 700HS has Philips 432 has 256 kbytes of which 128 is able to be used & 128 there for editing while a program is still running the machine. There are different versions but I think they can all do the drip feed DNC. If you need any help please ask again & will look up all you need to know. Regards from VWS in Australia.
This is maybe a stupid question but is trickle feed and drip feed the same thing?
A belive that when doing drip feed. The cable have to be of the full handshake type. Its DB25 in the machine and I would like to use the DB9 com port from my computer. could anyone tell me if this is the correct cable? ( Se picture)
I can't find any parameters regarding dripfeed but my manuals is in german and I'm not so familiar with that language. Deckeldoctor did you get your machine up and running with drip feed?
Do anyone have a nice G code program to share. I use Edgecam and will build ut a postprosessor for my machine. And I need some example programs to know how to build up the code. would love a program with drilling and/or 3D milling
i do DMG service, so i kinda know a bit about them LOL. not all 432 controls, especially early ones did drip feed, but they could be upgraded with a newer CPU and software. (not cheap though). If your not sure if you can drip feed look for a softkey called BTR (means between the tapereader). if you have this softkey then it should work. The communications constants usually start somewhere above N700 in the constants display. Scroll up and read the discription for each constant. you will need to match them up to your computer for RS232 communication. BTW a simple 3 wire is all that's needed
I wil check in the parameters after BTW. I have not been able to start the machine jet. Because I have 3x230 V AC in my workshop and the machine is buildt for 3x 400V. Anyone know if it is possible to modify the maho mh 500 c to 3x230V?
I belive that this could be hard to do. So I migth buy a transformator.
witch period was the 432 produced? could I see the production year in the serialnumber of the machine maybe?
smoregrava:
Probably the cheapest method is to use 220-440 step-up transformer. Much cheaper than replacing servo drives which are most likely 440 volt. The earliest 432 control that I ever saw, was from the early 1980's. It was replaced in the early 1990's by the 532. There were several versions of the 432 during that production run. The 432-12 was the last, I believe. The 432-10 was the most common around here.
