Hi Justintime, Actually the Z-Probe becomes your Z-Endstop... you can have both as well (Z-Probe and Z-Endstop)... in case of servo failure, the Z-Endstop will avoid a bed collision. You just need to wire them in series (if using Normally Closed contacts). I don't have the Z-Endstop... About the servo mounting on X-Carriage, check the mount I made: You can make a similar for your printer.. Beby AlexBorro - General Mendel Topics
@James, I have updated the Marlin official version with a fix for this issue in Bed Auto Leveling. Please download the latest version and look at configuration.h BAL section. Alexby AlexBorro - General Mendel Topics
@James, you should set the following line to false: #define min_software_endstops false @Skew, your Z axis get reversed ONLY after performing G29?? Have you tried moving the Z axis after a G28 ?? It doesnt make sense since G29 don't affect anything related to axis movements.. It is a bug, I have just realized.. I will try to fix it asap. Alex.by AlexBorro - General Mendel Topics
Yes, I got it.. If you have programming skills, you can modify the EEPROM data structure and add the planning information there.. Besides that, I will try to implement such feature in near future... Best Regards. Alex.by AlexBorro - General Mendel Topics
Yes, it will work, but you need to run it always before a printing, because leveling data are not stored.. and are erased after a G28 command (homing).. And be sure to keep the sensor always in the same position, specially Z-Offset (vertical distance of probe and nozzle). Best Regards. Alex.by AlexBorro - General Mendel Topics
I don't know what printer you have neither your bed material, but once you have an adjusted printer, you don't need to re-level the bed unless you change something.. The question is: it's really boring leveling the bed, specially if you have a 4-screws one... With auto leveling, the system do the dirty job for you... and the Z-high as well... It took me about 30 minutes to mount the servo+endsby AlexBorro - General Mendel Topics
The RAMPS 1.4 has 4 output for RC servos.. Please check at If you don't find, I can provide some pictures. Alex.by AlexBorro - General Mendel Topics
All the code and the instructions are available on github, check it out. About the servo.. humm.. We are about to test a IR sensor, but it is not an easy task... so far the only way I see is using a servo motor to lower and raise a mechanical probe.. But it is quite cheap.. you can get a regular servo for about $10... Best Regards. Alex.by AlexBorro - General Mendel Topics
Hi Guys, I have upmerged the larsbrubaker Bed Auto Leveling code to the latest Marlin version... It makes the printer setup and operation way easier!! check these videos: System demonstration: (English subtitles available) Printing in a really uneven bed: Do you want this amazing feature?? Best regards. Alex.by AlexBorro - General Mendel Topics
It is normal to run a little hot.. mine use to be at 80ºC~85ºC while printing.by AlexBorro - General Mendel Topics
My MakerFarm Prusa i3 8" printing: I've updated my printer with latest Marlin firmware and did some updates. Attached is the source code. 1) X axis direction corrected: Now the 0 position starts on left as usual. 2) PID enabled for Bed and Magma 0.4. During all the print, the extruder temp has a max deviation of 0.2ºC (for 230ºC, it keep in range of 229.8º and 230.2ºC). 3) The Extruder coolby AlexBorro - General Mendel Topics
I'm having a hard time printing ABS with this Magma End. Its cooler blows too much air enough to cools the print and bed, then warpings show up. To be honest, I have ordered a new hotend, I'm just waiting it knock my door so I can put this magma aside. Best Regards. Alex.by AlexBorro - General Mendel Topics
1) The RAMPS 1.4 has 2 power inputs: One for the heated bed (fused at 11A) and other one for the remaining electronics (fused at 5A). So you need to supply BOTH inputs... you can use 2 pairs of yellow-black wires or jump one input to the other. If you are gonna use a ATX PS, go for 2 pairs of supply... 2) Actually is not the RAMPS, but the arduino board underneath it... RAMPS send the input powby AlexBorro - General Mendel Topics
@drej, so far so good, but I have no experience at all with 3D printing, but I guess the 2 hollow calibration cubes I printed was pretty fine.. the first one warped a little bit and the second one, printed on kapton, has almost no warping (actually the cube corners warped 0.2mm only).. Since this is my first printer, I could say the assemble is pretty straight forward... Bear in mind the PDF insby AlexBorro - General Mendel Topics
I have just put together my MakerFarm Prusa I3 8" and it was almost straight forward. I liked the kit quality, I had just one problem with a piece not well cut but I could manage to fix it in minutes.. Colin offered to send me new pieces my I'm in Brazil so it is not worth.. The only flaw I see is the instruction could be better.. I prefer following written instruction than videos.. but.. that'by AlexBorro - General Mendel Topics
Hi Guys, I have just put together a MakerFarm Prusa I3 with Magma Hotend (made by TrinityLabs, I suppose). But I'm facing an issue.. This hotend is supposed to be mounted with a fan cooling the cold-end of the Magma.. and this same fan is cooling my bed and my print as well... Is there any way to run this Magma Hotend without fan and no clogging at all?? Someone had this issue and came up wiby AlexBorro - General Mendel Topics
Hi drej, I made my mind on the Prusa I3 based on reports found on the web. Let's point them: - Beautiful: Among RepReps, it is one of the most beautiful printers. - Easy to assemble: For a beginner, it is important. - Good print envelope (200mm x 200mm x 200mm) - Improved design over the well known and worthy Prusa Mendel V2 (as know as I2 as well). - I have found a great kit for a good price,by AlexBorro - General Mendel Topics
Thanks thejollygrimreaper for your comments! Actually, after a little more research, I have pulled the trigger on a Prusa I3 ;-) Let's see how it performs!! Alex.by AlexBorro - General Mendel Topics

Hi Chris, I took a look at the Prusa i3 model sold on RepRap Universe but I didn't like it that much. It is not complete... And I could not find for that Prusa i3 as detailed build information as I found for RepRapPro Mendel (http://reprappro.com/documentation/RepRapPro_Tricolour) About the nuts coming loose, thanks for the advice, I will drop threadlock in them.

Hi Guys, I'm looking for a 3D Printer to enter in this amazing world. I have made my mind for a RepRapPro Mono Mendel. It has a good build instruction and look like good quality product. Is there any concern about it I should know before pull the trigger?? I mean, project issues, high service rate, etc. Best Regards. Alex.by AlexBorro - Reprappers
Hi Bob, I appreciate your help. I noted Mendel can print bigger objects. It is 210x190x140 and UP3D is 140x140x135 (mm) About enclosed volume, the Mendel didn't have as well. Check picture attached. I was told the UP3D has a great print software with good features like auto build supports. Will I have same features with Mendel Software??

Hi Guys, I'm new in this 3D printer wonderful world and, as usual, trying to pick a model to play with. My question is should I get a pre-built one or build one. My main concern is printer and printing quality and durability. As electrical engineer, I have enough skills to build my one. I was wondering if a selfbuilt RepRapPro Mendel Mono (http://reprappro.com/products/mono-mendel/) would perby AlexBorro - General Mendel Topics
