Almost exactly a year ago, June, 2009, I bought and installed a Mitutoyo 2 Axis KA kit with two magnetic AT715 Scales. The unit is on my 15" X 50" Webb 4 VH Mill. It was purchased on eBay.
The X-axis measures 36" with 41+" total length and the Y-axis measures 16" and is 21+" long.
Just yesterday, I was using the mill with the DRO on and in moving the Y-axis, the DRO showed an error code 40. That means trouble with the scale. The error code only comes up on one portion of travel for about 2" on the outer portion of travel when the table is moved outwards. The rest of the scale reads normally and teh X-axis is still working fine.
I looked in my original paperwork and Mitutoyo says to send and any failed units back to the dealer. The dealer's invoice says to send any failed units to Mitutoyo. In other words, I'm on my own.
The Mitutoyo documents state that the units (KA DRO and two AT715 scales) have a 2 year warranty. They say to send the warranty information to them if something fails.
For the record, the units were very carefully installed and have had covers on them to keep out chips and oil. The are very clean and have worked perfectly up to yesterday.
I was wondering if anyone has experience with Mitutoyo on warranty service. I'm in California and there is a factory warranty station in Carson CA (Southern California). I will be contacting them on Tuesday after the Fourth of July. I was just wondering is anyone has been down this road before?
By the way, I think that Murphy's Law should have another line item added. Say, "If a thing can fail, it will fail at the least opportune time, usually on a long Holiday weekend so that you are most highly inconvenienced. If you are a hobby machinist, that will force you actually to converse with your wife on trivial matters and if you are professional machine shop owner, that will force the shutdown of the entire shop until the offending part is repaired or replaced."
Have you noticed how these things always break on long holidays?
Please place any thoughts on Mitutoyo warranty matters along with sincere expressions of sympathy, derisive comments and scorn below. Thanks in advance.
EDIT: Durn. I mean t to say DRO Problem......must be a bd keyboard.
