I think Heidenhain have stopped allowing free downloads, looks like they've become the same as those Jap bathplugs, FANUC

This is the best vid ive seen

E

grat vid, do you have a samlle code program so i can test my tnc 151 thanks

Nice video thanks! Greets from the Netherlands

Just bought an old Storebro cnc Combimill with a TNC-155 controller. After being used to Mach3 on my other machine, this is a bit of a learning curve.

Lovin’ the build broski, keep it up 💪

Good stuff

👀

That front end 😍

Gross positioning error a

Sounds nuts

Cool Video!

I work on a 40 year old TNC 155 (literaly one month older than I am) since like 4 years now, and it realy tickles my hobby-C-programmer brain in all the right ways. Return-stack of LBL0, Value of QXX, IF QXX EQ VAL GOTO LBL... all the good/bad things of assembler roled up in a "no security required" enviroment... a living fosile from a more simple, more civilized programming time without IoT... Solving problems in code. I love it :3

it was cleary expland thanks a lot but i still strugle with it :(

How did you fashion the enclosure?

Life saver! Thanks George

I need your help, on my tnc-155 machine, it can hold a maximum of 1000 blocks per program but I wanted to add more, is it possible? I have 3000 thousand blocks of space but it doesn't all fit in the same

On the tnc-155b/q wich one is the serial port? X26? Nothing in the manual about it or i can’t find it

great vid , i was trying to drip feed my tnc 151 46,000 lines via tnc server the other day it froze at 16,000 , have you ever had this issue ?

Very informative video, might just save my machine with that. But your link in the description does not seem to work. Can you check it please? Thank you!

Link in description appears to be dead

First HUGE detail, it’s not just a db25 connector it’s a usb to rs232, to db25. There are just plain usb to db25 cords out there and THEY WILL NOT WORK!!! Been chasing my tail over this for about a week now, with an rs232, now I actually have a serial port that tncserver recognizes. Well thanks so much, I’m a manual guy, but we have this old twin to your machine, well the getting it to work with fusion seems pretty easy, now to commit the ultimate sin and do this yucky cnc thing. Seriously thank you for putting out this vid, it made one easier step to actually making this old thing work, and push me into cnc beyond my 3d printer lol.

Hi George, Great video! Very informative. Do you know if the same process will work for TNC2500? Cheers

Hi George do you know if that pin layout will work for the TNC 145?

Poderia me enviar o plc obrigado

Great - I have to do this at my Hermle with the TNC155

Hi George, very nice. I have a Mikron WF21D with TNC355. And serial communication is really complicated with normal state of the art computers. Currently, I still have problems with the cable connection and am not able to communicate with the Heidenhain. Let's see what works here. In the end I will probably take the soldering iron in my hand again... Best, Stephan

thanks for you instruction, i'm struggling with my own "cnc adventure" to get the fusion program feed into a Heidenhain TNC410..

Thank you for your instructions. I followed your way for tnc370 and the MPs were sent to Machine. At the end , i clicked END button then I faced the "Processor check error b" error on the screen. May you help me with this error i faced. Thx

In Fusion there would be a PP especially for tnc 155 did you tried that out?

Dou you have the plc program for me?

This was a really helpful video. Thanks very much.

Hi George, Thanks for the video and especially the machine parameter file. Saved endless messing about trying to figure out the fine details of bringing my TNC155B back from "Oh no! The machine parameters. They're gone." I have a Maho MHC 700C which I left in storage for a few years without 3 phase power. So I expected to lose them. A big crane job got it into my shed and powered up, and I had to break it down into smaller pieces to do so. A lot of work just there. So it came up in German as expected. I hadn’t thought of the USB to RS232 cable until I saw yours. Bought exactly that one. Nice that it puts out 9V. A lot of them seem to just use the 5V USB which seems a bit low. The cable meant I could by a relatively new second hand laptop with Windows 10, rather than an old one with a DB9 com port. You go a bit fast at the end there, but I managed to get it by running the video at 25% speed. As well you can single frame in UA-cam by pausing and then pressing either the full stop or comma key for forward and back. It would be nice if you added a bit at the end that showed exactly how to use TNCserver (I started with TNCremo before I realised that was wrong) and then showed how to set all the tabs there correctly. My machine will only connect with ME mode with lost parameters. Maybe it has a slightly different Eprom revision. I spent a few hours messing about with that and with various handshakes and got it a half way through the file where is “stopped”. Then I realised that the fault was in the syntax of parameters 94 to 110. I’m lucky I have a punch tape of the final commissioning in 1990, which has to have correct syntax, plus a slightly different one from 2007 where someone went through and put all those parameters in the installation manual, which I used, but they got the number syntax a bit wrong (real numbers instead of integers). Your parameter file saved me days of entering as there are so many CR, LF, and space non printable characters typos are inevitable. I put it in Word and turned on the punctuation to see them all. I also used it to help the decode the entire punch tape. There are a vast number of repeat sequences so I made a template by just stencilling through the punch holes onto a piece of paper then just slid the tape along to pick up each repeat. So I only had to go through and edit the actual settings for my machine. TNCserver finds the correct COM: number and lets you set the baud rate, but it shows the rest ghosted (in some cases). If you go to Windows device manager you can set things in the serial port driver, but it doesn’t seem to reflect back to TNCserver. Some other sites show the setting as being 2 stop bits. That works on my machine, in device manager, when parameters are lost. My punch tape has even parity. That works too. I doesn’t seem to be sensitive to the handshaking at 2400 baud. Maybe it can empty the buffers fast enough. A bit on your cable. It’s definitely been tampered with. Actually, the wires look a bit big to fit the pins on the DB25. The “Mounting Instructions and Interface Circuit control - Machine” manual shows it in Figure 5.3 a). It should be what they call “null modem”, which is an old term for not crossed over. So it should go should go RTS to RTS etc. It’s the left cable in the diagram and is meant to go from the Amphenol connector on the TNC to the wall of the cabinet on your mill. Then the cross over you do is on the cable that goes to the FE 401 or ME101 etc. But it makes much more sense to do what you have done as we already have the Dtech cable. Note there is a stupidity in their cable diagram. It has 2 loop back wires from pin 6 to pin 8 on the DB25, RS232 connectors, but there is no connection to it on the cabinet connector. I think it’s there so you could swap that cable end to end, but they put different gender DB25’s on each end so you can’t anyway. It doesn’t seem to matter if they are there. Note it is missing on the 5.5 b) diagram below it because there is no active pin for it on the Amphenol connector. I swapped my cabinet DB25 for a DB9 as my Dtech cable doesn’t have the DB25 to DB9 adaptor with it.

Thanks so much for this video! I might buy a Fehlmann Picomax 100 with TNC150 in the next weeks so this video came in really handy.

Nice and informative video! I just started my retirement from machining job, 44 years whole and 29 years CNC. I worked first with Heidenhain TNC155B (MAHO 500W) and later also TNC530i (DUGARD EAGLE). 155 is an amazing control, with its parametric programming you can mill even complex mathematical curves and full 3D. Mastercam Mill 3 helped from -94 on, but still I kept programming with Q-parameters when I made my own canned cycles (threads, various L-shapes, squares, ellipses etc.) for later use. Those were interesting an very creative years.

George I need help for my Hidenhain tnc 124, my panel is not working , there is an error on top of the screen, Relay ext. Dc voltage missing

Thank you for your clear explanation! Now it Dripfeeden works for me (Fusion 360 + TNC 155P + Mikron WF21C). But then in the Heidenhain dialogue language. Everything seems to work, but at the beginning of the program execution when I call a tool I get the error message that there is no tool defined. That had been done a few lines before, but so it seems the TNC doesn't remember this ... Does anyone have an idea what might be causing this? When I transfer the program to the TNC it will work as usual.

Do you have a complete parameter list of the interact tnc155 can you sent me that?

Hi I have one of this machine but the parameters are deleted how can I get the parameters?

at work we have 4 cnc machines with heidenhain on all. the oldest has a tnc155 controller. I also run Fusion 360 with Generic milling post for Heidenhain TNC 155. cam.autodesk.com/hsmposts?_ga=2.156875579.1271040680.1607583034-815659367.1499820299 I need to think more about What strategies I run on the older machines idea that they can not run any strategies as machine can not so well keep up with reading heavy codes other than that it runs very well. I also use TNC 640, TNC 426 and TNC 415. I have been working with heidenheim for almost 25 years and it is the most reliable control I have experienced They have their faults like all possible other controls but I have not had any problems I have never had where the heidenheim controller does anything strange in the programs. I use drip feeding over Serial WiFi Adapter - RS232/485/422 Moxa brand from CIMCO DNC-Max Server

thank so much for sharing this! I´m considering buying a maho mh 700w with heidenhain tnc 425 and currentyl trying to evaluate if drip feeding is a viable workflow. so far I have not heard the best opinions about drip feeding in general (mostly concerning fanuc controlls I guess) but quite positive thoughts about it from the guy I´d buy it from. he has not used it a bunch though. so my general question knowing its a different controller and so on: do you trust drip-feeding to your machine? did you ever have hickups like the feed stopping and the machine doing something really stupid and dangerous?

How much would you charge for a project like this but with motor mount in the front?

Nice machine! I hat the same machine Nice machine voor machining smal parts. Now i have a micron 21 c whit heidenhain 155 i hope i can also conect it whit the laptop en do CAD cam . Thanks for the video

wow, where is your shop?

I have two of them , finally going to work on them next month. can't wait to see what you do to it. I'm in Ontario california don't know if you are to far from here just in case you need parts Gorge

It's really coming along! Great work!

Best of Luck George !!!

very interesting George ! thank you for all the work you did in describing this ! Joe
