Maho mh800w retrofit

Hi
Im new to linux cnc and linux in general. coding and programming is not my strengths so im looking for some help with my retrofit.
I have a maho mh800w which has a philips 523 controller. This has died multiple times and i have been lucky enough to repair it until now as the cpu board or graphics board has gone.
Time for a retrofit as im sick of drip feeding programs.
RotarySMP has been kind enough to forward on all his information which has been great to cross reference philips 432/532 wiring diagrams.

Hardware so far
hp elitedesk 800 g2
Elo touch screen
Heidenhain te425b panel
3 heidenhain 602d's
Mesa 7i97t, 7i84, 7i73, ordered 7i74+7i73

Warning i will probably be asking simple questions but i dont know what i dont know.

1st problem
I cant get a basic configuration to open. this is a basic config that tommy light shared in some thread.
Ive tried 10.10.10.10 and 192.168.1.121 with 7i97t and im lost.


ive done the mesa ethernet card manual as ive an intel Ethernet chip.
 This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).#

#source /etc/network/interfaces.d/*
auto lo
iface lo inet loopback

auto eno1
iface eno1 inet static
address 192.168.1.121
netmask 255.255.255.0

Please help. Paul


 

You have set the host PC's IP address to the Mesa cards address.
This will not work, all IP addresses on a network must be different.

I would suggest setting the host IP address to 10.10.10.100
(and the 7I97 to 10.10.10.10)

Hi PCW 
Thanks for such a speedy reply

(manual extract HARDWARE CONFIGURATION IP ADDRESS SELECTION The 7I97T has four options for selecting its IP address. These options are selected by Jumpers W11 and W12.
W11 W12 IP ADDRESS
DOWN DOWN FIXED 192.168.1.121(DEFAULT)
DOWN UP FIXED FROM EEPROM 
Note: The as shipped default EEPROM IP address is 10.10.10.10. This can be changed via the mesaflash utility)

I have tried multiply attempts using the following jumper pin locations
Down UP =  Computer ip 10.10.10.1 -7i97t unchanged at 10.10.10.10
Down UP =  Computer ip 10.10.10.11 -7i97t unchanged at 10.10.10.10 
Down UP =  Computer ip 10.10.10.10 -7i97t unchanged at 10.10.10.10 

also tried 
down down= computer at 192.168.1.1  & 7i97t at 192.168.1.121
down down= computer at 192.168.1.0  & 7i97t at 192.168.1.121
down down= computer at 192.168.1.121  & 7i97t at 192.168.1.121

same results

Ive spent the last 2 days at this and im lost. 

I cannot get mesaflash to find the board name or anything.
I cannot get mesaflash to update either. my installed version is something like 3.4.8 or something like that and ive read i need 3.5.something for 7i97t. Im at home now. cant remember exactly. anyway ran all the bash command listed on github for mesaflash update and it says im uptodate with 3.4.8 which i dont think is correct. 

Is there a way to verify correct connection between the computer and the mesa board without using Mesaflash or ping as the bash command?ping has returned ''working fine'' on many of the attempts above but still unable to launch this basic config without errors? what leds should be lit with a correct connection.

What ip address should be in the Hal file? the boards or the computers?
Thanks Paul.

Hello Paul,

Also have a MH600W, although mine is a bit older with the 432/10.

Did you try manually updating your version of mesaflash by downloading and compiling directly from the github repository? Instructions are directly in the readme.MD

github.com/LinuxCNC/mesaflash

Finally got the connection going. For newbie’s to Linuxcnc the leds on the 7i97t Ethernet port should be flickering while you’re pinging the ip address from the computer’s terminal. 
such a simple piece of information. 
I managed to figure out with my wifi connection ON, the Ethernet connection is dropped so simply disconnecting the WiFi connection allowed the connection with the mesa board.

Thanks vrnf 
I’ll have a look at updating mesaflash tomorrow.

Have you retrofitted your mh600w? Or still running the 432?
