What's a good PCB assembly service?

I'm looking for a board house that has decent pricing on runs from 10 to 100 assembled PCBs. I used Seeed's PCBA service to produce one prototype already. Their pricing is pretty good. However, their parts catalog is limited. If it's necessary to use something they don't have, they charge a LOT extr...

Re: Why you should NEVER use SketchUp, which is a steaming pile of crap.

Late update: In September of 2016, I bought a laptop with a 17" display, and installed Autodesk Fusion 360. I had thought to import all my SketchUp stuff into it, and go from there, as there is an importer. However, what gets imported is meshes, not F360's abstract breps. If you create a cube i...

Re: I cannot figure out PETG . . . please help

With PETG, the Z height setting is critical. PLA and ABS will forgive you for your Z being a little off, but PETG will just slowly accumulate until it becomes a problem. My advice is to use the smallest Z height you can, while still getting adequate 1st layer adhesion. 255 is a decent temp for PETG....

Re: I cannot figure out PETG . . . please help

Make sure you are not over-extruding. Do a filament calibration, like in the first steps of my Delta dimensional accuracy calibration (see sig). Make sure your Z height is set as close to perfect as possible. Over-extruding, or having the Z height too tall, will guarantee that PETG builds up and eve...

Flaky thermistor (or connection) for sure, probably a shaky PID tune as well. Easiest thing to try: replace your thermistor. Second easiest thing to try: replace the wires and all connectors between the thermistor and your controller. You can lash some two-conductor wire to your existing cable harne...

Re: e3d v6 problems

Unless you changed your firmware at the same time, I don't know why it would do that unless it was getting a bad sensor reading and halting on that account. Does anything show up in the console when you connect over serial? Shut off the printer and unplug the hot end heater and thermistor connectors...

I know about the Replicape. They would've had access to a bigger pool of developers if they had used the Pi. I think they used the BBB because of its coprocessors, which they call PRUs, but that was never necessary. The Pi has a DMA controller, and can send waveforms to stepper drivers many times fa...

Re: Impressions: Duet vs. Smoothie

I'll continue to use Smoothieboards because I wrote the heuristic calibration system for them, and it works better for me than Duet's firmware. It gives you a full depth map after the calibration, as well as after setting up Z-only correction (if you want to), so you know what you're really getting....

Re: How-to: Dimensional Accuracy Calibration for Delta Printers

I get what your saying, but understand that my glass isn't what I would call flat and seems to warp pretty good at a few spots. I don't think glass can be warped unless it was handled very roughly during production, jostled badly before it was done cooling. During production, it's in a molten state...

Re: How-to: Dimensional Accuracy Calibration for Delta Printers

GeckoTek won't be flatter than glass. There are tiny undulations on the surface. I got sick of how easily the plates get scratched and have taken to clamping the glass disc to the GeckoTek aluminum base, as it works very well as a heat spreader.

Re: How-to: Dimensional Accuracy Calibration for Delta Printers

If you're using a 0.5mm SeeMe nozzle, I recommend setting extrusion width to 0.55. You may measure that it's less than that, but that could be due to contraction from cooling. It's usually not a good idea to use any value even slightly less than the nozzle diameter. If you do, you may see weird arti...

nope. still waiting, looks like they are making a lot of compromises, so we'll see.

Re: How-to: Dimensional Accuracy Calibration for Delta Printers

Consider that a 50x50mm solid box has 122 times more XY area than one side of a single-walled 50x50mm box. I would expect to see more positional errors pile up given the increase in area. In Delta printers, there is generally more positional error between two points the further they are from each ot...

Well, this is a significant find. I always thought Moire patterns were a necessary artifact of using Delta printers, and you could only eliminate them with some crazy high-res steppers. You've really got something here.

Re: Effects of microstepping and segmentation on print qualty

Setting the layer height to a multiple of the golden ratio (once you figure out how much distance a full step takes) spreads the peaks out enough that they stop being visible. Based on Bruce's last few prints, it looks like the Golden Ratio idea works pretty well. I see only straight lines, with li...
