DRO Digital Readout

Welcome to first video of many to come. I’ve had several requests to make a video about the Digital Readout (DRO) that I have installed on my 30W Raycus Fiber Laser system. Here is a quick overview of what it is, how it works, and where you can obtain one is in the description below.

Update: The price on these has changed. Link below is for a 24” model. Shop this around.

Features:
* Aluminum rule can be cut to fit length and application
* Super Large easy to read display which can be set to Inch, Decimal, Fractional and Metric
* Magnetic Remote Display with 76” cord for easy installation and routing
* Use vertical or horizontal
* Measure range (travel) is 0-24” with an accuracy of .002” per 6”.
* Reading Rated at .001”/0.01mm/12th/Inch

At the time of this video, the unit was retailing (for the 24” model) roughly $60.00

Thanks for sharing your secrets, experiences and making these videos. Planning on getting my hands on a JPT 30w sometime in the future and there really isn't enough of these sorts of videos around. Keep it up!

Thanks for the video! I've already purchased a DRO, but was having trouble figuring out the best way to mount it. I never considered leaving the top floating, which was where I was running into my issue. Motivated me to get that sucker on the machine today!

I’m late to the party on this video, but thank you. For some reason I could not wrap my head around how I would mount this on the laser. Thank you for a nice visual and informative explanation.

My boss sent me home with his new 50w fiber. He bought this with it. No idea what it did lol. We only engrave 3 parts really at 3 different heights. I just found the cleanest burn for all heights and wrote it down and adjust. I might set this up though cuz he said in my free time I can use it for whatever all be doing alot different heights. Thanks.

Dave, a great video from one veteran to another I wish you the best on your channel! I got DRO two days ago and it should be mounted here soon. I love your work. It's not biz for me just a hobby after 37 yrs of service I have to do something. DOL!!

Thanks for the idea of the DRO. mine came yesterday. I got the absolute version, which retains origin, which I set at the focal height of my 175 x 175 lens. I generated an excel spreadsheet that I put in material thickness of what I am marking, and it adds that to the zero(where I set origin) and that is where you adjust your height to. I also made a setting for my 70 x 70 lens. which the focal point for that is 165.25 mm lower, so it subtracts that distance from the origin and adds material thickness.

This is amazing! Thanks for this video. Of course the price now is $147 but still well worth it in my opinion.

I put one on mine several months ago and I love it. I used the same model. I liked it so much I went back and bought one of their calipers too. It's probably nicer than the DRO. Btw, the extra USB port is for their bluetooth module so you can download measurements to your phone or computer. I bought that too but so far haven't found a use for it at all.

Great video. I may go back and release the top mount on mine and see if it moves more freely. It's good now but every once in a while the readout seems a little unreliable. I am curious if it is binding up a little. We shall see.

I love mine I am glad I found you and suggest this makes life simpler

Great video! My laser is on order and will hopefully arrive soon. This will be one of the first mods that I do. I noticed that the link goes to a dro with 6 inches of travel. Is that enough? For some reason yours seems longer in the video but it might just be hard to tell scale in the video.

First of all thanx for sharing your knowledge, tips & tricks. Not many out there who do... I wanted to ask, I have a 30w Raycus as well, how do you know the zero of your lens is 100? My machine wears a 175x175

[prontoimages]

Great video Dave, UK 🇬🇧 Veteran here. Keep up the good work. Question though, if yuh know that head zero is don’t you just then zero the DRO to zero/datum at that height?

[rok]

From my 2+ years of experience with iGaging DROs, they are not very repeatable. If you move it up & down a few times then move back to zero, they can be off by 0.05 mm or more.
This may not matter in your application, but just be aware these instruments cannot be completely trusted .

There is a useful “relative distance “ feature on DRO that allows you to measure distance from a point at which you switched from absolute to relative coordinates. This helps in avoiding silly mistakes when you want to move from current point by specific distance but added or substrates the numbers incorrectly
:-)

[RichLeeFL]

What scan head do you have on that laser? It looks different than the standard Sino-Galvo head.

[Johngtaxi]

Ok. Silly question. But with the lens not all the way down to the table, Wouldn’t it be 100mm plus the distance between table and lens?

[scottishie]

So do the numbers change as you move your scan head up or down

[bugness]

No, you'd zero your DRO at 100... Also, you could have moved the pointer on the built in scale to read accurately... there's screw holes for that.
