Hi, folks,

Many know that these boards were shipping with missing IC's, mine was too- here are the pictures - what I would want to
know is that if I add on teh IC's would the U and Z axis be enabled, I have already designed my machine to work with
these axis and was somehow not contemplating not having them on the control board, since I purchase stuff ans stack till
I have enough funds to proceed - I took the long time back bought controller board and wanted to get it on the machine
when I have noticed these issues, hope I can get em solved with the help from Tim or macro or anyone else.

I need help on the following
1. I see HCPL 2630 optoisolator, I am guessing that needs to be added to U26 and U25
2. I am guessing U33 is 26LS31 in SMD form as used for X and Y
3. U28 shows some absurd marking as L247 which is not an IC name - kindly confirm what U29 should be??? this is to enable
Z axis limits
4. I will not be adding U31, U32 or VR1 or VR2 as I am not using 2 laser tubes (is that what it would have been used for)

But for all this to be fullfilled I would want to know if the firmware on the V1.6 board would actually support it - its
a bit void to see that after acarrying out all the changes and still the board does not work.
Hope you folks can help!

Regards
Irfan

Marco, request you to find out and reply.

Marco, please reply to the first post. are you again out in China and not able to access the forum?

You bet, I was in China. This time, it's not interenet issue but a more serious issue. I got beat up by a Western guy who was very mean to a waitor. I got knocked out and sent to hospital. 3 days later (now) I was able to use computer to check email and forum. This is crazy, not even a talk and the guy turn and hit me. If I wasn't food poision a day ago, it won't be that bad I guess.

I'll get more information and will post it here once I have enough info.

Just added TLP281-4 to the empty slot of U29 will enable Z limit. Just confirmed with the tech

Now all the new cardas are built-in with the option after my complains. They assume not too many people use that option and trying to save cost.

I'll be 'Home' on 29th

Marco what about my first 2 questions - If my Z axis dont work with out U26 and U25 what is use of adding Z limit ic???

"1. I see HCPL 2630 optoisolator, I am guessing that needs to be added to U26 and U25
2. I am guessing U33 is 26LS31 in SMD form as used for X and Y"

Hi Marco - hope you have reached home safe -

kindly get answers for the above two points -

btw does the firmware of the Version 1.6 board support z and U axis?
