Question: I'm currently building a workshop, and my intent is to put the unit in the workshop. If I put in the order next week, when do you estimate the unit will be delivered? If it arrives before the workshop is done (which i'm not opposed to) I will have to put the unit in the garage, and getting 220 to it will be interesting.
QuickAnswer: Once you have paid for the laser machine, it is your machine. If you need us to hold onto the machine for an extra week or so, that is not a problem. There is no extra charge to do this. I would rather the laser machine be installed where you want it to be (your workshop). We don't want the laser machine to be moved much at all. Just let me know when you plan on being finished with your workshop and I can try to schedule shipment around that time frame.

Question: What do you know about financing the laser costs? Would it be better for me to lease the laser machine? Do you do financing or leases? What companies will do the lease?
QuickAnswer: Leasing any equipment is a serious choice. Make sure you understand your lease options before you send any payments to any lease company. Paying cash is always the best option... Even a small bank loan is better than a lease contract ( my opinion )...Rabbit Laser USA does not do the lease. Lease companies are listed on our payment options page. . . . .

Question: I have a part of my laser machine that is broken. Do I need to buy it from a chinese factory, from USA representative, or my local hardware store?
QuickAnswer: Some parts of the laser would be very hard to find inside the USA. They could be purchased from a laser factory... If you speak Chinese then it is easier. Many factory reps speak english until you have a problem. Some factory reps suddenly forget how to speak english or blame problems on the language barrier.

Rabbit Laser USA is a reseller representative and we can sell you most any part you would need for the Chinese style laser machines. Some general hardware (nuts and screws) are metric and can be purchased from a good hardware store.

Many parts of the Chinese laser machines can be purchased from, Lowes hardware store, Ace Hardware,, or ...

Question: Why do I need to replace my mirrors?
QuickAnswer: Mirrors start to fail and reflect less laser light due to: Oxidation from humidity, Scratches from improper cleaning procedures, fumes/dust burned into the lens during normal usage.

Question: My laser does not produce light.. My Laser does not "fire". What is wrong? How do I fix the laser to make it fire?
QuickAnswer: See if you forgot something normal. Is the chiller on? Is the main door closed? Is the Laser enable button engaged? Is the chiller alarming? Is the water clogged? Is the laser power setting high enough (laser power/corner power)? Is the mirror alignment right? Is the focal lens dirty or blocked?

Question: Our 1290 rabbit laser is doing something unexpected starting locations and I don't know how to fix it. I think one of the students messed with the config file, but don't know where to look. I have tried shutting down and rebooting the computer and laser cutter but that won't correct the problem. The problem is no matter what we import or draw a project inside in the LaserCut 5.3, it want's to start it in the upper right corner of the laser cutter. We can have it positioned anywhere on the table and calculate the tool path, but as soon as we tell it to start/cut it will go to what I call the machine's home/datum position in the extreme upper left corner and begin there. How do I fix?
QuickAnswer: This sounds like a parameter setting of "Logic Origin". You need to cancel the logic origin. This is done inside the operator pad.

Question: What is the min / max values I can put in for speed, power, and corner power in cut mode?
QuickAnswer: Speed - Min should be above 0, Max should be below 1400 Power - Min should be above 0, Max is below 100 Corner power - Min should be above 0, Max is below 100

Question: What does corner power mean?
QuickAnswer: “power value” that is used on corners and angles.

Question: What is the min / max values I can put in for frequency. In Hz?
QuickAnswer: The "frequency" applies to RF laser modules. We find that 99 percent of Chinese laser systems use glass CO2 source. This feature does not apply to glass CO2 power supplies.

Question: What unit is the overlap value? mm?
QuickAnswer: Distance to over-cut a closed polygon at the start/end points.

Question: What is the min / max values I can put in for speed, power and scan gap in engraving. I noticed that 325 and 625 went the same as 150000 for speed.
QuickAnswer: Min speed for engraving should be 101. A lower engraving speed might be used on odd versions of the LaserCut 5.3 software. Actual speed depends on accel / decal rates with your engrave size.

Question: Engraving seems quit functioning cleanly in small areas. I'm writing 24pt test and the Tops of my T's and P's are large and clear but the vertical parts are not clear and sometimes not even there.
QuickAnswer: You are engraving too fast for the charge/discharge ability of the glass CO2 laser.

Question: We are moving into a building that isn't hooked up with a high voltage line. What are my options for 120V single phase @ 80W? Do I read correctly that you can supply me with the xformer "TX-110-220-2"?
QuickAnswer: We can provide a transformer that converts 120 to 240VAC(single phase). This transformer is quite heavy and will cost a significant amount to ship.

Question: I'm still unsure on how to level my laser tray holder (the metal black box and rails that the honeycomb sits inside).
QuickAnswer: Adjust the jack screws at each corner. Shim the non-level portions of the honeycomb

Question: Since we've decided to abandon our auto-focus, I'd like to set up a manual focus gauge. I think I remember you saying that it was 35mm from the bottom of the knurled part of the lens holder to the optimal work surface. Can you verify this for me? Or correct me?
QuickAnswer: The expected distance from surface to the knurled chamfer is 39mm. It is best to find the optimum focal point and then measure from the surface to an edge or feature that is easy to measure.

Question: I'm upgrading the ventilation system. Do you have a CFM of draw that you recommend?
QuickAnswer: Go as high CFM as you can afford and put up with the noise.

Question: On these new mirrors what side do you use? Gold tinted or the side that looks like a regular silver mirror.
QuickAnswer: The laser needs to reflect off the gold side.

Question: I try to start my LaserCut software and get an error that says "Plug in softdog and restart the software". The software doesn't start. What is wrong?
QuickAnswer: Make sure the USB Dongle is plugged in and the device drivers are loaded into the Windows Device Manager.

Question: I want to export DXF files from Corel or Adobe Illustrator. What settings do I need to export?
QuickAnswer: AutoCAD 2000, 16 colors, JPEG, *Preserve Appearance, *Outline Text
