Hi Again! Don't know how it happened but my tablet now works! I finally got some free time and decided to take the requested pix. Not wanting to give up I decided to reload/rerun the Waxbee.jar/File/New from template - Firmware/Program Device - Press button on Teensy - Unplug/Replug USB. Mind you I've done this many times before but all of a sudden there I am moving the pen across the board and the mouse/cursor is moving! Now, as time allows I'll be testing it in a couple of programs.

Since I took the time to take the pix I might as well upload them.

This is great! Can't wait to start experimenting with it!

I'm having a problem with tablet pen detection. The tablet won't detect the pen when LCD is on top of it. My LCD is Dell 1503fp, the original build.

The LCD is just too thick. The pen's range dies at about 2/3 of the LCD's thickness.

I tried tweaking the potentiometers on the pen but there's not much improvement except the pen is acting worse without LCD. (Random clicks)

There are 3 screws of potentiometers. Do you know which one does what?

The only thing I know about playing with the pots is that you should carefully remember their initial position  (taking a picture might help) and play with one at a time.   I do not know which is which (all pens are more or less different).

@boomanvibe:

Ratio: You have to pick the right template:  a UD-1212-R is better "emulated" to a XD-1212-U ! (not a XD-1218-U).

Eraser not working:  That's a regression in WaxBee 0.11.  Update to WaxBee 0.11a.

Try using my Jitter Monitor to get a sense of small changes in jitter as you adjust pots.

Hi,

I joined the forum to get information - Me and a mate have 5 Wacom A3 talets between us. I have a UD-1218 and a Quantel Henry version I pulled out of a skip in London's Wardour St. 13 years ago and oddly, my mate help start the company that was throwing them out - though we never met until recently.

Okay, so the question; I have the tablet (9 pin D connector) to power supply (Cat5 connector) cable. Can someone supply us with a pinout from the Cat5 to the PC's serial connector so we can test these tablets.

If you are in London maybe we could meet up?

Thanks

Welcome! I am in Canada.  

This pinout is available in this forum. There are diagrams et al.  The first one to post this info was Tanassi.  Here's one link I found:  http://forum.bongofish.co.uk/index.php?topic=1427.msg9104#msg9104

Another success story: I successfully retrofitted an old UD-1212-R with a Teensy 2.0. I haven't spent much time actually using it yet, but the current Wacom software recognizes the tablet correctly. I'm running Windows 7 x64.

After some thought about mounting the Teensy, I ended up removing the power switch and using a strip of that double-sided foam mounting tape to stick the Teensy to the Wacom PCB, with the USB connector pointing outwards. This isn't the most rugged solution, obviously, and I can't push the button on the Teensy easily, but it will do for now.

Thanks a bunch to all of the folks who have contributed to this project. I'm pleased as punch to have my Wacom working again.

yay! Happy that it works for you. Cool  ...oh and Welcome!   Good idea for mounting the teensy.  This board is so small there are no holes for screws, so making it sturdy to allow a mini usb connection is a bit annoying. And the problem of the button is another thing.  Can you take a photo of the result?

Thanks for the welcome. Here are a couple of photos:

* board view.jpg (329.39 KB. 1600x1047 - viewed 561 times.)


* port view.jpg (136.71 KB. 1600x594 - viewed 538 times.)

I'm glad that you asked for them. When I looked into the case before taking the photo, I noticed that I hadn't seated the main PCB correctly over one of the pegs on the case, and the PCB was slightly bent! Not good in the long run. So, since I had to open the case back up anyway, I took a photo of the modified board.

Probably the easiest way to deal with the button is to drill a hole in the bottom of the case.

Nice job!  I like where you got your main ground from.   

Drilling a whole for the button is actually a good idea -- It can be small and you could press it using a non-metalic stick or large enough to fit the finger tip.

Can I also use one of these two ATMEGA32U4 boards?
http://www.ebay.com/itm/Leonardo-Nano-Pro-Mini-ATmega32U4-Support-Arduino-IDE-1-0-1-Bootloader-Ready-/360492013744?pt=Vintage_Electronics_R2&hash=item53eeff98b0

These are cheaper for me (shipping is 10 dollar for the Teensy). Or are there even cheaper models I can use?
I guess only the ATMEGA32U4 chip is supported by Waxbee? Or also some other chips?

Only works with the same chip. Just a detail with the non Teensy ones: the bootloader is different so you will need to flash the .hex file as a separate step using whatever tool that can do it in for this board. In theory it should work but I never tried myself. There is a very good chance it works actually.

Hi there this in my first post,

i have an UD-1218-R (working). it has a serial port so it does not run with win7 x64. i have checked the tutorial titles but there is not a title says "converting UD-1218-R from serial to USB" so my question is should i follow UD-1212-R tutorial (which feels like the right one) or GD-1218-R?

thank you.

Rasim.

Follow UD-1212-R -- the control board, I believe, is the same (just the content of the EEPROM is different -- the 'removable' chip with a white sticker on it -- we do not care about that one). 

GD-1218-R is a completely different beast.

To be sure, compare the pictures of the boards to see if it matches. If it does, tell us and we can update the information in the relevant threads.  Luckily for you, I've added support for UD-1218-R in the latest WaxBee. (waxbee 0.12a)
