We put in several man hours on each Bodor machine before we are comfortable enough to send them out to our customers. Again, this does not mean the machine is no good or not worth the time, it just needs the attention of a trained technician or a very tech-savvy individual to get her tuned up properly.
Here is a short list of hurdles you will need to overcome before the machine functions the way it was intended to:
1) Rail Alignment - If the gantry rails do not share the same angle down to a fraction of a degree, then you will we certainly lose power at the back/right corner of your table as the laser head will either dip or climb due to the variance. I can't stress this enough with the 150W beam, you need to be hitting dead center on all mirrors and on your way into the laser head at all areas of the table. If you're off by even 1mm in either direction, you will experience a loss in power, melted O rings and eventually a cracked lens.
2) Bed Leveling - this is the first step in making sure that the laser beam remains in focus throughout the entire span of your 900 x 1300 work area. Without it, you will lose focus anywhere there is a deviation of roughly 1 mm. This requires that you crawl into the bottom of the machine, loosen tensioners and being to individually turn ball screws until each corner of the bed is equidistant to the nozzle on the laser head.
3) Laser Head Squareness - It is not uncommon for the laser head to sit at a slight angle in either direction. Especially with the 150W beam being as broad as it is, you need to ensure that the laser head is perfectly square to your gantry and table in order to prevent a loss in beam transmission as the beam makes its way to the focal lens. It's not uncommon for people to call and tell us their laser head is getting very hot or that the O ring around the focal lens has melted and through repeated use, caused the lens to crack.
4) Mirror Placement - The location of mirror 1 and mirror 2 are never in the right place. With 150W beams, you need all the real-estate you can get in order to ensure the complete beam is making it to the focal lens. This is a very tedious process and involves many many burn tests to ensure each mirror is catching the beam dead center. Mirror 2 requires a spacer to bring it away from the gantry some so that the beam enters the laser head dead center. Unfortunately, the Mirror 2 bracket on the Bodor does not have the proper adjustment to bring it closer or further away from the gantry. Therefore, you will never get full beam transmission which will result in early entry to the laser head and a tremendous loss in power.
5) Gantry Squareness - Once everything is perfect and I mean absolutely perfect, then we can run some cut tests to make sue the gantry is perfectly perpendicular to your rails. It usually isn't, but every now and then a machine will surprise me and will come from the factory within acceptable tolerances. Otherwise, you can instruct the machine to cut a square, but you will get a rhombus instead. We shoot for .5mm or less of tolerance from one side of the machine to the other. Getting this just right requires unbolting the coupler that marries both left and right rails to the Y motor and making adjustments to an individual side. Sometimes, the belt tension comes into play as even just a few turns of the tensioning bracket will pull one side of the gantry in either direction.
6) Red Pointer Alignment - Once it is all said and done, you can finally adjust the red pointer so that the cross hairs are shooting dead center to your laser beam when it's in focus. This anyone can do, but if you've never done it before, count on your patience to be tested.
7) Training and Maintenance - Lastly, once the machine is in proper working order, we will training you on everything from operating the machine to proper maintenance. This is a nice added bonus we include since the tech is already there in your presence.
I don't mean to discourage you. On the contrary, I don't think there is a soul on this planet that has invested as much time as I have into making the Bodor machine perfect. The very first machine we got from Bodor years ago had all of these issues. We ended up flying Russ Sadler in from England to help us sort through all of these issues. There was a point in the process where we were about ready to give up on Bodor all together, but after many long night of tinkering and learning what needs to be done, we realized the machine was not at fault and that the factory does a great job of giving you a machine that is 90% of the way there. The last 10% takes so much time to get right, it would never be feasible for them to incorporate it into their QC procedure.
Since then, we have developed an extensive quality control procedure of our own that involves all of these corrections. If you were to order a Bodor laser from our company, it would take us 2-3 working days before we can sign off on all of these things and deliver a 100% perfectly functioning machine. For anyone else considering a Bodor purchase or any laser purchase from China, expect that you will have to put in the same amount of work. We have tried many brands and they all require that a trained technician lay hands on them before they are fit to ship. Any dealer that is turning around a product without putting it through this arduous inspection, does not have your best interest at heart and is more focused on just making a quick buck.
Let me know if you would like to work on getting someone out there.
