To be pedantic, power supplies dont 'push' current, they provide it. Its not a constant like voltage. What mods did you make to your Solidoodle - because as delivered the power supply is more than capable of the required current. There was a batch of badly manufactured ones that have too much tension on the leads to the PCB which tend to fail due to stress, but its a fairly simple fix and not related to the load being placed on the PSU beyond load == thermal stress..
And your 30 amp will still be overkill even if you max out all the possible mods you can do: 15amps for a Silicone Bed, 2.5 amps for the Extruder Heater, 4amps *peak* on the Steppers, 1 amp peak for all the fans and LEDs and 300ma for the ATMega - so 23 Amp if everything was turned on at 100% and busy at 100% (which it isn't often, since the Bed and Extruder are in PID cycles probably 80% of the time... steppers shutdown after 30 secs of inactivity) - but it never hurts to have more current than you need. The bigger issue then is the traces on the PCB for the Power MOSFETs
True in this case voltage is constant and current is the variable in respect to time. I believe I have one of the newer power supplies and it has issues. Yes, 30 amps is overkill but I got a good deal on the power supply. Anyways, I plan on tricking out the power supply using a pic. For me it is all about doing a projects to keep up on my skills.

... And the source code and schematics would be posted to what URL now - as per the required licencing of the Printrboard and Marlin Firmware.. its been several weeks now since your 'announcement' of using Open Source Hardware....

Solidoodle 2/3
The latest firmware works both with Solidoodle 2 and Solidoodle 3. By default, it will be compiled for SD2. If you have a SD3, open the Configuration.h tab and change the line
How do. I get to where they are talking about? Do I need another piece of software?
And what size screws will fit in those holes in the frame for hinges? Its like 2.87mm
Just to be clear, all SD3s go out with the appropriate set of SD3 specific firmware.
]]>all I want to do is be able to calibrate my extrusion stepper. do I need the arduino IDE ?
No, thats just an EEPROM firmware setting. Config->Firmware Config Setting ...
]]>why isn't solidoodle releasing information on their hardware? I get that its new, but we by nature are a group of tinkerers...
]]>Not only do they have a different print volume but all the little details will be incorrect:
- Thermistor selection
- Steps per mm for all sxis
- min and max temps
- PID values
- etc
firmware uploads are still possible, with a few process tweaks
Solidoodle team could simply tell us how to solve this issue...

I want to know, please, help me!!!
