Nice job! I'm still drip feeding the old delta 20 on mine, I've been thinking about retrofitting my J325 but I'm curious to see how much more advanced the retrofit options will improve over the next 5 years or atleast until the ole delta 20 craps out for good
I've had a few people ask about the wiring diagrams for this retrofit. I spent a good week studying the original machine schematics and redrawing them into a much simpler form. The originals were hard to follow. I have created .pdf files from the schematics below. I did have to create a few boards myself to translate some signals and voltages. I didn't draw the entire schematic for these. drive.google.com/open?id=0B4rFEnBUk1tGSzdCSXMwclNzcm8 drive.google.com/open?id=0B4rFEnBUk1tGenk1NXpDX1V2cTA
Hello Rick, I now have a Tree325 in the garage ready for this retrofit. Is it a possible you can do a video of the inside cabinets with some insight into the beginning steps on this retrofit? Thanks,
NIIIIICE!!! Did you document your process? Is it on the interwebz? I have a lagun 4824 with a dynapath delta 50 that died and I have a kflop and kanalog in another machine that ***isn't working!*** I'm in a limited funds and two dead mills shituation and I think i can make it function with what I have in the shop. Just trying to gather info to make a decision. Thank you for giving me hope with this vid!! I know this is like 5 years ago so its a poke in the dark.
Here are the schematics: www.dynomotion.com/wiki/index.php?action=ajax&title=-&rs=SecureFileStore::getFile&f=/2/28/Kanalog_to_Tree_Journeyman_325_by_Rick_B.pdf
Did you use the original servos and servo drives/amps? I have a tree journeyman 325 with delta 20 control and a journeyman 350 with a delta 50 control they both work but the delta 20 starves for code when engraving complex things I'm looking for an affordable way to upgrade it
Rick, I am about to purchase this machine as attempt the retro fit with Dynomotion. Are you open to share some information / answers to some of my question along the journey? I am a bit electronically challenged. You also mention below you created a few boards. Would you be willing to make a couple more of these boards for purchase? Thanks, PeteW.
Sure, I'll tell you what I can. If you have the same exact machine, you should be able to use my schematics and save yourself a bunch of work. I used the Kflop and Kanalog boards only. The encoders on my machine were single-ended and the Kanalog board requires differential encoder outputs. These inputs also have some fairly low input impedance, so they require a fair amount of drive current. I built a board using 6 RS485 drivers. These take the single ended signal and create a differential signal at the output. This is also how RS485 works, so it's pretty easy. The other boards I made were to convert higher voltage signals to 3.3v signals for input directly to Kflop on the headers. These inputs were for the front panel switches and MPG switches. These boards used opto-isolators for this purpose. None of it is really difficult. No, I have too many other pending projects to make more boards, but I'll tell you how to do it. Alternatively, you could use the Dynomotion Kconnect board.
Rick, I am going to look at the machine today and get pictures of it. I am still looking into how I am going to get this 4600 lb. machine moved form the where it is at into my garage.
Well that's a job unto itself. If you don't have a forklift handy, you can use a long pry bar to move the bottom up a little at a time and shim it with wood blocks. Do each corner in turn until you have it high enough for a pallet jack or machine dollies to get under it. Then it's the same process to put it down again. You will want to level the table up once you have it in place.
Thanks once again for you reply. I am hoping to pick it up next weekend. If I have questions regarding the retro fit process with the Dynomotion boards in the weeks ahead, and you have time to answer them, is this best place to correspond with you?
Hi Rick, will the Dynomotion Kflop and Kanalog boards work with a 4th axis added on to it? I also have the same Tree Journeyman 325 machine but it has a delta 30 control. Looking into retrofitting the control with keeping all the original servos and motors. I am trying to figure out what i can save and use and what i need to buy. Does using the Dynomotion boards limit you to one software or could you use Mach3 or 4?
Its added here:www.dynomotion.com/wiki/index.php?title=Main_Page#Wiring_Diagrams Thanks again! A post on the forum would be great also. Someone was asking on cnczone.
I've got the same model of mill at work, and we'll probably need to retrofit it. How hard was the Dynomotion equipment to install, and what original parts carried over?
It took me a couple of months to do the whole thing. The dynomotion boards work great, but you have to work out your wiring. What inputs and outputs will connect to the dynomotion board. Also, you will need to write some code in C, to make the whole thing work. It's really not difficult though. I was going to do another video detailing more about the retrofit. I'll try and get that done.
Hello Rick, This is exactly what I want to do to the Tree 325. Can I get copy of the schematics from you. I was hoping to use the existing servers and power supply. Thanks, PeteW.
Schematics are here: www.dynomotion.com/wiki/index.php?action=ajax&title=-&rs=SecureFileStore::getFile&f=/2/28/Kanalog_to_Tree_Journeyman_325_by_Rick_B.pdf Do you mean servos? Yes, I used the original servos and servo drives. The power supply is built into the drive. Mine is servo dynamics. The drives require a -10-10 volt analog input for servo speed and direction control. Kanalog generates that for you. The same is true with the spindle drive. I still have the yakasawa spindle drive and spindle motor. I did have to tap some connections off of the spindle drive to feed back encoder signals from the spindle to Kanalog. That yakasawa has some hard to find connectors on it for this purpose. I had to buy a bunch of them. If you need one for this, I can send you one.
I plan to do another video when the shop isn't 120 degrees. I'll show and explain all of the things I built and modified during the retrofit.

Thanks,
Will do that soon
Great ... looking forward to it.
Did you use the existing Tree325 Power Supply or did you retrofit for single phase?
Thanks,
Still running 3 phase 240 power.

Hi
Impressive upgrade. Can you share with us how you wire the ATC to Kanalog / Kflop ?
Here are the schematics:

Rick B thanks for your kindness and sharing your expertise with us.

Rick, how is your CNC setup working after 2 years?

Wow Great job on the schematics. Is it ok if we add them to the example Wiring Diagrams in our wiki?
sure, I was going to post something on the forum for other people.

Rick B that would be great. Thanks. I have an email in to Dynomotion, and we'll see what happens.
