Ortur LM2 Drag Chain Modification

Simple video explaining how I added Drag Chain support to the X and Y Axis on an Ortur LM2 20W laser.

Fantastic Chris - I loosely followed your work and just completed this. Instead of making the brackets and mounts from aluminum, I modeled and printed my own to fit the machine. I used the same flat stock and angle that you showed here. If you're interested in the STLs I could post them.

Very nice, a good drag chain setup is a nice upgrade for these type of lasers. My drag chain setup is very similar- got L channel aluminum extrusions (same sort of aluminum angle that you used) attached to the frame/gantry to support any sagging in just the same way. I've got a Sculpfun S30 Pro with the 900x900mm expansion kit- it's a 10 watt so the huge area isn't too useful yet but I'll be upgrading to a 30 watt laser soon so it'll be much more practical. After I get my 30 watt I'm looking forward to my first CO2 laser. I've noticed more accuracy with the chain and can run at higher speeds- not by a lot but it's noticeable, I had wires rubbing on my enclosure and the air assist would flap around a lot at speed.

Well done!

Great tip about where to locate the connections Thank you

Good job well done 👍

I would like to just make a new wire harness are these 2.54mm JST-XH Connectors

[@cedwards874]

I'm not sure, which is why I left the original connectors and just added wire in the middle.

[@Steve-su9ny]

Hi, I'm doing this for a Neje Master 2s Max, could you tell me the type of wire you used to extend your cables? Also, great job. Very tidy and professional.

BONJOUR france . TRES BIEN VOTRE MODIFICATION. where did you find your big protective filter from the box and which goggles you used with your prescription glasses

[@cedwards874]

These are the goggles www.amazon.com/gp/product/B00U6UHRCI/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 On the filter, are you referring to the orange plexiglass or the fan on the rear

Nice Job! Where did you get your height adjustment attachment from?

[@cedwards874]

The part that mounts on the laser module came from someone on the Ortur facebook group. The one in the cabinet is a Lab Jack from Amazon.

[@FinsAndAllScuba]

Thank You!

Is that an openbuilds acro? Heavily modded if so

[@josvanhoof7616]

Wich color heatshrink solder connector did you use?

[@cedwards874]

I was able to us the smallest and the next size up.

[@josvanhoof7616]

Thanks very much.

I have the jtechphotonics sheet and using the included safety glasses in addition to the sheet and my eyes hurt. At this point I think these lasers have a dangerous amount of IR or UV light.

[@cedwards874]

I agree, I do seem to notice a bit of a headache when the laser is running. I also cover the Plexiglass with a large black lawn and leaf bag when the laser is running.

[@stevegraves3609]

The Ortur 20watt laser does not give off any UV or IR light . The lasers spectrum emits light at 440-450 nm. The intensity is the only real issue .

[@cedwards874]

@@stevegraves3609 We'll just have to agree to disagree on this. I'd rather have people err on the side of safety than lose their sight.

[@danharrier3618]

Chris, I also have the Ortur Laser and love it, but could you let me know what kind of wood you used for your plantation shutter louvres in your other video?

[@cedwards874]

@@danharrier3618 I used Basswood, not sure if it was Northern or Southern, I would guess Southern.

dimensions of you pieces please

[@adamoverton9428]

How much did you extend each wire?

[@cedwards874]

About 6" to 10" can't remember exactly. I staggered the connectors so they were not all bunched up in the same location.
