So just because other boards don't include a 24v PSU does not mean that you won't need one, and you need to account for that when comparing prices.Ĭohesion3D's LaserBoard and Mini Gerbil use 32-bit CPUs (STM32).Īctually the LaserBoard uses a different LPC1769 chipset running a custom variation of Smoothie firmware we call Cluster. Even people that run the stock M2 board acknowledge that the stock LPSU is underpowered for 24v. The C3D LaserBoard is 4 axis with the high quality stepper drivers for higher power and Z Table + Rotary direct support as discussed above, has multiple laser control mechanisms to cover almost every option I have seen out there, air assist control that is already configured in the firmware, is highly isolated and protected against the harsh environments inside lasers, can run the LCD screen for untethered operation, and has the high quality power supply included. It only supports 2 axes, but that's usually good enough. The $89 price point of the Mini Gerbil is a lot more reasonable. You can jog the machine using menus on the C3D LCD. The panel/LCD adds another $40 and it doesn't even have jog buttons. How much that value is worth is different for every person.
In order to use a Ruida with a K40 you would have to add a 24v PSU, external stepper drivers, and then wire all that up, so factor the total cost, time spent, and skill required over a "drop in" solution like the Cohesion3D. It's not 2/3 as good as a Ruida controller. So this is actually a better value than our previous board. The power supply is included in the $200 price. There are 4 drivers built in which means that it can drive a Z Table and a Rotary directly from the board. The LaserBoard has built in Trinamic stepper drivers which are very quiet, result in smoother motion, and can drive more current than step-sticks. The total cost of this from us was over $200.Īlmost a year ago we released the new LaserBoard, which is the current product offering. The Mini came as a 2 axis board, meaning that in order to drive a Z table and/ or Rotary you would have to get additional drivers and hook them up to the Mini. The power brick we provide is actually a high quality 24V4A unit. We started recommending a separate power supply, then started offering one, and finally included it with all the boards. During its lifespan we learned that the K40 Laser Power Supply could not provide enough current to power it and that this was causing lots of dropouts and job interruptions. Originally there was the Cohesion3D Mini board.
Then they bundled some no name PSU and increased the price by $50. I'd like to provide some clarification on the points that /u/inu-no-policemen commented:Ĭohesion3D's controller used to cost $150.
