Re: SmartCore Dual HotEnd - 10 years ago
Parts are printed and i make mistake with dimension. Redraw and now print the second piece again. At the end the distance between the (center) of the nozzle willl be 41,8 mm ... More news to comeby Zlob - Smart_Rap

SmartCore Dual HotEnd - 10 years ago
Hi all, i'm printing the new dual hotnd support. I've draw in a very easy way. At the end if all works i will put file onto thingiverse. Just to know anyone else tryed this ? (I use e3d v5 hotend)by Zlob - Smart_Rap

Autolevel issue - 10 years ago
HI all. A friend of mine built a smartcore exactly like mine. The only difference is the sensor: mine is a 4mm sensor his is a 8mm sensor. I'm using the firmware from smartfriendz github repo, latest version for mk8. I've try to do the same step i do to setup the autolevel: - g28 to zero axis - some G0 Z-0.1 -> -1.2 to put the noozle at a paper sheet distance - put the value (-1.2) to marlin sby Zlob - Smart_Rap
Re: SmartRap ignores Z offset stored in EEPROM - 10 years ago
So wich is the correct sequence to setup a SmartCore ? I use this one: g28 to zero the axis; send some g0 z-0.1 thru 0.5 to find the nozzle offset (paper sheet method) store the value (eg. 0.3) into config.h file at these lines: 446 #define X_PROBE_OFFSET_FROM_EXTRUDER 40 <- distance beween nozzle and sensor center (approx) for X 447 #define Y_PROBE_OFFSET_FROM_EXTRUDER 0 <- distance beweeby Zlob - Smart_Rap
Re: Induction Z axis probe/z_min_endstop in Repetier Firmware 
- 10 years ago
Sorry i'm not using Repetier. It's a test i will do but can't tell you when... BTW, have you read this: ? Forgot to mention the config.h that rcjoseb wrote into another thread, for my smartcore. The config is supposed to work with rcjoseb machine and IS repetier firmware. Just save ot to a config.h file, than upload to repetier firmware config site and go on. Hope it helpby Zlob - Smart_Rap
Re: Another newbie's Smarcore build - 10 years ago
Hi, I use a cheap "aliexpress" e3d clone too. Look like u are using a too low PLA temp. I usually use 200° or 205° without heated bed, and 195° with heated bed. Also, check that the temp. sensor is in good contect with metal. If not use alu foil (cooking one!) to made good contact. Hope it help.by Zlob - Smart_Rap
Re: Induction Z axis probe/z_min_endstop in Repetier Firmware - 10 years ago
I got same problem too. I forgot to think that printer use "ABSOLUTE POSITION". So, if u want to raise eg 0,5 mm up u must give the "G0 Z-0.5" command and NOT "G0 Z-0." command five time. Remeber to do this too: #define min_software_endstops true // If true, axis won't move to coordinates less than HOME_POS. Hope help.by Zlob - Smart_Rap
Re: Another Smart Rap Core build - 10 years ago
And at the end, the printer works. I had some issue with ZSensor but i can arrange it. Some picture: First attempt Ham as ckeychain Some guitar peg for my son: The printer work. Now i want to add a hotbed AND a fan, but the sensor i have is 12 mm and the fan i found re for 18 ... Still wait if someone can reduce the hole.

Re: freno motore asse z - 10 years ago
In Marlin, config.adv: #define DEFAULT_STEPPER_DEACTIVE_TIME 3600 -> in secondi, in questo caso un'ora. In questo modo aumenti il timeout ma NON risolvi il problema a fine stampa e/o mancanza di elettricita'.

Quotec11610o QuoteZlob ... Ho provato in tutte le maniere ma non c'e'verso di fare muovere l'asse Z oltre il finecorsa... non puoi abbassarlo un po' il finecorsa? voler andare oltre quando sei appoggiato non credo sia molto saggio. No, il "finecorsa" e' un sensore di prossimita' e mi serve per attivare l'autolivellamento. Il problema e' bisogna conoscere la distanza fra il nozzle e il sensore.by Zlob - Elettronica e meccanica

Re: auto livellamento asse Z - 10 years ago
Salve a tutti. Sto cercando di tarare la mia smartrpcore ma non c'e' verso. Mi spiego: seguendo le varie guide, devo stabilire la distanza fra sensore e ugello. Una volta effettuato il comando G28 (zero assi x,y e z) dovrei eseguire una serie di comandi G0 Z0,1 per stabilire la distanza fra nozzle e sensore (piano?).

Hi all. After lot of test, with lot maerials i really need help with Z axis. Today i reprint the z axis, and use the V 1.2 . Still having some trouble: as i use 10 mm rod the sledge touch a little backward. But the worst thing is which kind of plate i must use.

Re: Pulegge 40denti si svitano - 10 years ago
QuoteManuHC Zlob consigli quindi di mantenere la puleggia stampata invece che acquistarla in metallo? Grazie intanto del link Io proverei con una stampata con magari 2 o 3 fissaggi.

Re: Pulegge 40denti si svitano - 10 years ago
Li trovi un generatore di pulegge anche a 3 fermi a 120°. Per avere il profilo GT2 alla voce profile, metti 12 (se vuoi altri profili, butta un occhio al sorgente.) Con gli altri parametri ti scegli tutto il resto (altezza, idler, fermo, n. di denti etc.) Salutiby Zlob - Elettronica e meccanica

Re: problem with induction sensor - 10 years ago
Check the connection between Sensor and Signal on ramps. If you have a multimeter check Volt between sensor signal out and ground in both state (light of & light on) to see if something change. If not, the sensor is out OR the resistor OR the 7805 are out.by Zlob - Smart_Rap
Re: Another Smart Rap Core build - 10 years ago
Quotemandrav I mean, once you *manually* level your bed once, there is really no reason for it to become non-level. Why have an auto-leveling process which tries to correct your non-level bed when you could just level it once and be done with it? Also, with auto-leveling enabled, your Z motor(s) will be constantly working throughout the print adding even more variables to the final print qualityby Zlob - Smart_Rap
Re: Another Smart Rap Core build - 10 years ago
Another silly question: the proxy sensor must be lower than hotend or upper ? In both case any suggestion about how mm ? Any suggestion on how instruct the firmware to use autolevel bed ? Thanks !by Zlob - Smart_Rap
Re: Another Smart Rap Core build - 10 years ago
Quotesmartfriendzthat's strange with the build volume ? Normally, if you enter 250x250x250 in the print size, you will go for 315 mm X rod size, for example and that should give you around 250mm printable on X ( with a 250 wide plate of course ). I will check again though.. Well, just re-generate with JSCAD, version "1.0.8 mar 2015" with these parameters: X,Y,Z = 250 wood thikness = 17 xrodby Zlob - Smart_Rap

Again, i have count the teeth and they are 20. Driver are 4988 for sure: i read (with a big lens !) the value directly from the chip.
