VERY large bed laser

Post by Charles Jones »

I just finished moving my new flatbed laser down to the shop. It's a GWEIKE LC1530D model. 1.5 x 3.0 meter cut area. It has a RECI W6 tube. Haven't turned it on yet, but excited to fire it up and start cutting some plywood!

Do you have fire yet Charles? I am interested in how it works for you. The exhaust must be from under the bed, is the bed blades or a honeycomb material. Thanks Gene

I have been on the VERY slow road to getting this machine set up. Anyway, I have finally set everything up and cut some plywood. It works fairly well and is quite accurate. The exhaust is from under the bed and the machine was equipped with a blade type bed with a removeable honeycomb bed installed above. Knowing what I know now, I would rather not have paid for the honeycomb. There isn't enough clearance between the blades and the gantry to actually hold the honeycomb and a piece of stock. Live and learn. HOWEVER, I am getting the same result as a honeycomb table by stretching 1/4" steel hardware cloth over the blades. The blades are easy to level/flatten and the hardware cloth provides the extra support to keep small parts from falling through. Why not allow small parts to fall through? because of the aforementioned exhaust. I am using the exhaust fans to provide a small amount of suction from below. Its enough to flatten large sheets of 1/4" plywood, although not enough to flatten 1/2" sheets. If I allowed small parts to fall through, I would quickly loose suction.

In other news, the machine was originally specified as having 1500 x 3000 mm capacity. However, I was able to plus that up to a full 5' x 10' (1525 x 3050mm) This gave me a little bit more wiggle room to load oversized pieces of plywood or the 10' planks I cut that justified this machine in the first place.

Overall I am very pleased with the GWeike build quality. It is the second machine I have purchased from them (The first being an LC1390N.) Both machines required a lot of TLC and setup, but have been solid performers. Are they comparable to a Trotec or Kern system? Not in terms of out of the box handling, but when I consider the relative bargain price for these machines, the extra work I put in is well worth it.

Is your blade bed parallel with the gantry over the whole bed? I ended up making a lockout for one side so that I can level it left to right [on a cabinet model] as well as manually front to back. It actually works well. Also I have a lot of problems with aligning the #2 mirror in all four quadrants- still have not solved that completely. The larger the bed, the larger the problems I have found. Gene
