Dynapath Delta 20 Troubles
I've just acquired a Tree Journeyman 310 Mill with a Dyanapath Delta 20 Controller. When I start it up I get the usual E-Stop error which I can clear. That is followed by instructions to "Reference the axes." I have been using the following procedure without success.
1) "Mode"
2) "0" (for Jog)
3) "R" (for reference)
4) "Enter" (with or without this key, no action)
5) "Start"
I get no response following these steps, which I got from a previous post. The boards inside the controller show all of the proper settings. The power is good and correct. When I loosen the cables at the servos I get limited and eratic movement. The connections are all tight and clean.
Any ideas? I'm awaiting the factory's manual arrival in the mail, but I'm not pinning all my hopes on that.
Problems Solved: For what it's worth...
Well, I sent my whole Delta 20 controller for repair to Al Strelbicki at Parts & Smarts in WI. They diagnosed a faulty DC power supply as the culprit. They also reloaded the machine parameters, which had been corrupted. It was about $1100.00 plus shipping but I have a Tree Journeyman 310 that works like a charm now. I was impressed with the level of service and knowledge at Parts & Smarts. I highly recommend them if you can't fix it yourself.
A couple of notes might be worth sharing with other novices who stumble upon this post.
1) If your machine has a feed rate override knob, don't forget to turn it on. "Off" overrides the axes feeds entirely, defeating any intended movement. (How many hours did I spend pondering this predicament; I'd hate to say)
2) If you had your parameters reset, you will most likely want to "Intilize" the machine. You don't have to do this, but it saves a heck of a lot of time by not having to reset the controller every time you accidentally travel past the machine limits. The process is described in the Dynapath manual. I know; they are expensive ($210.00), but worth every dollar if you are serious about learning what this baby can do.
I'm still pretty new to this control, but I've picked up a lot already, and I have the manual! So, if you've got a problem feel free to drop a line and I'll give you my best unqualified advice, or share a few pages from the Dynapath manual with you. But don't ask me to post the whole book. Dynapath is still in business and guards their copyright jealously.
Re: Dynapath Delta 20 Troubles
Hello Redzilla,
When you recapped the supply, did you change all of the electrolytic caps or just the output side caps?
I ask because I only recapped the output side and am still getting ~ 300mv of ripple on the +-15 volts, but the 5 volt looks good with only 25 mv.
Thanks,
Bryan
