Hi all. I'm in the process of building a HBC and I'm wondering where people mount their extruders. Has anyone noticed a difference in print quality based on where the extruder is mounted? Not only interested in HBC mounting but also where you guys mount it on your printer?by wes1007 - General
Use an Arduino a transistor and a relay. Smoke detector provides a signal to the Arduino which then triggers a transistor to turn a NC relay off. code it so that once the smoke detector is triggered you either press a button to reset or you just reset the arduino. Be careful with smoke detectors. There are 2 types (cant remember the types). One picks up smoke and the other picks up burning withby wes1007 - General
QuoteSodombar The tool is a kind of sensor. I use this function to drive the motor : // Takes a single step void takeSingleStep() { Z_STEP_WRITE(LOW); delayMicroseconds(stepPulseWidthInMicroSec); Z_STEP_WRITE(HIGH); delayMicroseconds(timeBetweenStepsInMicroSec); } In relation to the state of the sensor : // GO UP if (state1 < threshold && state2 >= threshold) {by wes1007 - Firmware - mainstream and related support
So how does this tool determine when it is on the surface? How does it drive the stepper motor? What is the tool?by wes1007 - Firmware - mainstream and related support
I dont see why you need to home it so often? after you have homed it once it should be fine. You can instruct the printer to go back to the same position it was homed to by giving it the command G0 Z0 What does M3 M5 M12 and M13 control?by wes1007 - Firmware - mainstream and related support

Hi Guys, So after having problems with my FETS on my RAMPS board I decided to build an external PCB with my new FETs on it. (2xIRFz44n for hotends and 2xIRLB8743 for heated-bed and possibly a heated chamber system) The problem I am having now is mapping the pins correctly. I have had a look in pins.h and changed the values I thought were correct but it hasn't made any difference. I have confirby wes1007 - Firmware - mainstream and related support
If you are electronically inclined you could grab some new FETS and wire one up to an aux port on the board. change the pins in firmware to tell it what to switch and then you'll have 2 individually controllable heated beds.by wes1007 - RAMPS Electronics
Quotegmh39 It's a 5A 250W psu. Apparently it doesn't want to turn on at all now.... I have a 12V 30A switching psu that wont turn on either even when plugged back into the printrbot.

So what your saying is after I upload the modified firmware I should do a M502 and then M500? Or is that only if i've done all the settings on the smart controller? I don't think i've seen "use standardconfig" and "store EEprom" Before on the controller :/ Ill have a look again when i'm in front of my printer.by wes1007 - Firmware - mainstream and related support
Was having a problem where my settings (acceleration , Max velocity etc) where different in firmware and on the LCD. I edited the original question by mistake instead of posting a reply. Heres what I found: You have to go into configurationstore.cpp and increment the version number: // IMPORTANT: Whenever there are changes made to the variables stored in EEPROM // in the functions below, alsby wes1007 - Firmware - mainstream and related support
Are you talking about that gap between the infill and the shell? Is this happening on different models or specifically this one?by wes1007 - Printing
Is no one interested in this concept? :/by wes1007 - Let's design something! (I've got an idea ...)
So I've been needing to print a new set of Z and X carriages for my P3steel (an I3 variant) and the current models out there just don't seem to be what I want. This has got me thinking we need a modular carriage system. Something where each component or at least ad-ons can be taken off or put on without replacing or reprinting the whole part. For example: you've just bought a new printer/ buiby wes1007 - Let's design something! (I've got an idea ...)
try a glass plate with ABS Juice.... A mixture of ABS pieces and Acetone. Been using it a lot and its been working fine.by wes1007 - General
2 perimeters if I remember correctly. I'm running ABS on my system and at 250. I have a 40mm fan running on the hotend. Even without retraction I'm getting same results just with lots more stringing. I'll try printing with more perimeters as a test and I'll make sure that its printing the interior ones first I'm using cura ATM because of the nice GUI but I am making the switch to slic3r soon aby wes1007 - Printing
Hi guys. Been Haviga few issues with regards to holes. Layers near a through hole seen to stick in a little more than over areas. I thought it may be a problem with filamment oozing since I didn't have retract set up at first. I have now set up a retract of 1mm and I no longer have any stringing yet the problem still exists. I'm on a p3steel with a Bowden setup and a wades extruder. Any helby wes1007 - Printing
Forgot about the dxf file. The measurement is 17mm for any one that is curious. I guess that is true about gravity keeping the z axis down. Will maybe make a redesign for the copper TR8*8 but I have thenby wes1007 - Prusa i3 and variants

So after being fustraded by this stupid heated bed problem i gave something else a try. After being told not to use D9 for the heated bed i looked into what other options i had. It was still D9, however not directly. I have set up a relay to run off of D9 Which is hooked up onto a separate rail on the psu. This seems to be working well so far. Did a test heat to 40 degrees and it overshot a littby wes1007 - General
QuoteAndrewBCN Quotecdru QuoteAndrewBCNThe heated bed from the D10 connector: DON'T!!! The large current traces and the 11A fuse on the RAMPS are only for the D8 connector.RAMPS 1.4 doesn't have different size traces for D8-D10.They're all the same. .... As far as I can see the islands (marked as dotted lines) for the 11A circuit path provide a lot more copper than the traces for the 5A circuitby wes1007 - General
Okay went and checked the wiki and you guys are right. D9 and 10 are max 5A combined. I for some reason thought it was higher than that. As a test I'll remove the get from D9. It'll also give me something to work off of until I can get spares. Maybe Fridayby wes1007 - General
I can't remember exactly but I'm sure on my board the traces went different sizes... I'll double check that. The heated bed only draws 6 amps. I'm sure the rise for D9 and 10 is bigger than that? All I'm wanting to test is that the heated bed alone on one of the channels works. I'm not going to print like that. Not in front of my board right now but when I am I'll have a look. I'll need to see iby wes1007 - General
I get that. The new PSU I used is a 450w proline PSU. They are pretty decent quality. However the fact that the heated bed runs fine when powered directly off a 12v line from the psu and not via the ramps board makes me believe that there's something wrong on my ramps board. I might try running the heated bed of d10 as a test. With nothing else rubningm if that's worjig I might take the MOSFEby wes1007 - General
I've tried 3 different ones. 2 were older one was brand new and more than capable of supplying enough juice. Bit I still experience this problemby wes1007 - General
QuoteAndrewBCN Check the resistance between the D8 terminals with the RAMPS disconnected from everything. If it's zero you have found your short circuit. Nope no short between terminals with everything unplugged and off.powered up is the same story. When powered up and a tempreture is set for D8 i get 12v on that line. If it was the mosfet surely id have problems regardless of having a load onby wes1007 - General
Did some experimenting today and it looks like its a problem with the ramps board. Heated bed measures a bit over 1 ohm, Its drawing a total of 6 amps and doesn't trigger the over current protection when plugged directly into the 12v line on the PC PSU however when its plugged into D8 on the RAMPS board the PSU goes into over current protection. If I unplug the heated bed and set a tempreture fby wes1007 - General
Quotedc42 Quotewes1007 Quotedc42 I am very happy with Chinese LED power supplies. Like ATX PSUs, they are short-circuit protected; but unlike ATX PSUs, the voltage is adjustable - which is handy if you have a heated bed that struggles to get hot enough for ABS printing - and they don't require minimum loads. The downsides are that they are probably not as reliable as top-brand ATX PSUs (OTOH youby wes1007 - General
