Bittele has let us down again and in turn I feel like I have let you the customer down. The 200 drivers we received from Bittele were thoroughly tested and were found to be 1oz boards again. We waited a long time for them to rectify their first mistake and have the components moved from the old 1oz boards to new 2oz boards but again we received 1oz boards.

How we tested this:

• 1oz copper drivers can only provide about 2.5A or 4W of optical laser power and those are the exact values we found when testing these new drivers
• Next we took samples from 2oz copper boards, 1oz copper boards and the boards we just received under a magnifying tool and we found they match the copper from the 1oz copper. (Top – 1oz copper, middle – boards we received, bottom – 2oz copper)
• 

• Next we did a 4 point measurement test to get a more solid comparison with the 2oz copper boards, 1oz copper boards and the boards we just received. These measurements so the clear difference in a 2oz copper driver and the ones we just received.
• 

• Our last test was to guarantee the issues we saw came from the copper and not any components, so we took a 2oz pcb and we swapped all electronic components from the boards we received to the 2oz pcb and this driver worked perfectly. This showed us that the parts were fine and it is 100% a 1oz copper pcb

What are we doing about it?

As you know, we decided to order drivers from Makerfabs just in case anything like this happened. We did, they have shipped 200 drivers and they are currently going through customs clearance in a local sorting facility. We have provided POA this morning and have our invoices ready to be provided as soon as they are requested from us. The estimated delivery date in June 1st but DHL has a tendency to drag customs clearance, so I will be on the phone with them multiple times a day until we get it cleared.

We will go through the same testing process above to make sure they are true 2oz copper driver pcbs and we will ship as soon as they pass testing. Andy pointed out that as soon as those Bittele drivers failed their first test I should have taken a day to update you all, I will make it a point to delivery even the worse news in a more timely manner. We are in the same situation here as I am not happy until you have received your LaserBeam orders and I will not stop working until I get it done.

This update is for all LaserBeam customers that have not received their orders. 

Most of you probably know that we have been dealing with supply chain delays for the past 3 months and recently that delay came to an end. That is the good news, copper heatsinks and power supplies arrived and the laser diode assemblies have been assembled. 

The bad news is Bittele, our pcb manufacturer, manufactured our drivers on 1oz copper pcbs instead of our requested 2oz copper pcbs. This will cause a delay for LaserBeam orders shipping out. 

The details: 

• We cannot ship out drivers with 1oz pcbs, this will cause the voltage regulator and other key components to operate out of safe specifications
• Bittele and their team is committed to rectifying this mistake
• This will delay the driver shipment by 20-25 days which delays the LaserBeams shipping out

What we are doing about this:

• Bittele has been instructed to remake all pcbs with 2oz copper
• Bittele has been instructed to disassemble all components from the 1oz copper pcbs 
• Bittele has been instructed to reorder all generic capacitors and resistors that cannot be disassembled from the 1oz copper pcbs
• We will place a completely new order for 200 assembled drivers with PCBway in the hope that they can potentially manufacture and ship drivers before Bittele can.
• Both this new order and our delayed order will give us 6 months of driver stock so that we can avoid this type of delay from ever happening again. 

Like always, if you cannot wait for the new drivers to arrive for any reason. Please send in a ticket requesting a refund, we completely understand. Feel free to reorder when we begin shipping product. I appreciate the support of all customers.

Hello all Laser customers, Monday December 20th we began shipping our LaserBeam pre-orders out. I am working everyday to make sure we can get our first 300 pre-orders out the door before the end of the year.

I will be in the office next week, testing, packing and shipping LaserBeams.

I made the decision to begin shipping before our resource section was live because I did not want to delay shipping while I finished our resource section.

Each laser and laser driver is tested before shipping and I will have resources posted before Thursday end of day.

For now I will be providing the User/Safety Manual pdf with our tutorial video that was made for the Youtube Channel earlier this year for those who have received your Laser before Thursday.

I appreciate you all for sticking with this project and I’m still working hard until you all have Lasers and resources.

Cheers,
