Right now I am using the LCD screen to home the machine then move to my material origin so I can set the offsets. The BLTouch probe should deploy and the Z axis should move down. Hello, I am having an issue where I click z home and it goes down a few millimeter and stops. Unfortunately i noticed, that during print the Z-axis wont move upwoards when a new layer begins and it should move upwoards. If combined with a Z and P field (example: G31 P312 Z0.7) this will set the Z height to 0.7mm when the Z-probe value reaches 312 when a G28 Z0 (zero Z axis) command is sent. Z-Axis Move Planning in Practice And that is the big limiting factor with Z-moves: the distances are very small. I went to a parallel configuration. Everything has been running fine since updating. The left axis continued to occasionally move down when I raised z by 1 or .1mm . See if the z-axis moves. I also exchanged bent Z-axis threaded M8 rods that came with the kit for new, more straight, stainless steel rods. 0.6 mm (0.6 mm is example, note your actual) This is a very slow process from the LCD screen. If it looks a long way above, click the Z move 1 button, then go down by 0.1 until you reach z= 0. The main thing here is to write down wheter an axis is moving the right direction or not. Has anyone experienced this before? Using Attached is my configuration.h all of my changes are bounded by #ifdef ChuckMod. Specifically, the Z-axis will move down (and trigger the endstop) but it will only make a quick noise if I try to move it up. i use Marlin (from this site) on a ramps1.4 with dual endstops X and Y. I have 2 questions regarding endstops. I see. The patch i meant only … A move of just 0.1 or 0.2mm doesn’t give much time or space to accelerate and slow down again. I've finished building my first Prusa i3 from 3dprinterczar and am working on getting the motors correctly calibrated and have ran into a problem. Been using marlin 1.1 but wanted newest auto leveling and other bells and whistles. If not, you may need to tweak the offset Just to clarify I didnt add in anything extra besides changing the settings to speed that worked in my previous version. Min software stops are currently disabled, as I try to set the printer up. stays at the same level during the entire print. On Z-stop trigger, right Z moves up, left Z continues to try to move down. prusa-i3 marlin electronics z-axis firmware X and Y homes fine but Z all of a sudden moves upwards instead of down towards the endstop/buildplate. Move the nozzle down to level of the print bed; LCD navigation: “Prepare> Move axis> Move Z> Move minus 0.1mm increment” and make a note of the value or type “G1 Z-0.5, G1 Z-0.6″, so on, in to the serial monitor, until the SoliForum - 3D Printing Community → Software & Firmware → Help! I have full manual control of all axis... moving up/down/homing ect, all with manual control. You have to go into Prepare-Move Axis-X,Y or Z Axis, .1, 1 or 10mm then you can move one axis at a time. You might only be able to move an axis using the + for that axes. Ramps 1.4 I did use M119 to test and it is open and when I touch the probe it says triggered. So is it is not the drivers. Write a quick script to move the head somewhere up high, then terminate without the X-homing command. Tried to implement latest Marlin on my reprappro with ramps 1.4. Write any script, and while the gantry is up high, pull I was having the motors lock up on moves. Z axis won't move down past the plane the extruder was at when the printer was turned on. Z-endstop switch is monitored when moving Z axis down via LCD menu or G0. I have been able to draw some forms to check if it’s square. My MPCNC is almost finished. Baby Stepping is a feature from Marlin Firmware that allows you to move the Z-axis up or down in small increments in order to fine-tune the first layer height. Save current position and move to filament change position. I have TH3D Marlin firmware installed. We will proceed to uncomment the USE_ZMIN_PLUG options. Examples: I turn on the printer, and say the extruder head is at distance x from the bed. … When I try to move the Z-axis, using the hardware buttons in the LCD menu (without a computer connected), it only goes down, when I both increase, and decrease, the value of Z. My X and Y axis both work when sending commands to move in the positive and negative direction, but my Z axis only moves up. X any Y work fine, both Z motors move down just fine, when homed. Prepare > Move axis > Move 0.1mm > Move Z Slowly move the Z axis down until you have the correct first layer gap (paper or thin card method) Note the distance on the display e.g. If the gauge is loose then you need to lengthen the travel on this axis- you are working on … Pro-tip: You might want to keep you finger near the on/off switch on your printer. M119 shows all endstops open. Auto-home one or more axes, moving them towards their endstops until triggered. To set the Z axis home offset on the 3d printer, you will use g-code commands including M206 for the home offset, M500 and M501 for the Marlin Firmware EEPROM feature, and G1 for controlled move to Z axis zero position. X-Y dual endstops: It works fine but on the Y axis when I move the head after homing 1 motor seems to start in advance. Today I installed stepper dampers for X and Y. Replugged the wires and presses autohome. This tends to be from insufficient current. Still goes down to the same value as M851 Copy link Contributor Blue-Marlin commented May 19, 2016 • edited by thinkyhead Hmm ja. Using Pronterface version 2013.10.19, connects to the printer (using the IDE and command line), the X Y and Z motors I just finished assembly of Anet A8 (Prusa i3 clone). No problems there. Hi, I am new in CNC but have few years experience in 3D printing. G'day, I have a new Ord Hadron and having an issue with the Z axis. Move your Z axis fairly high, and then 'Home Z' or G28 Z to test Z homing. I inverted the Z-axis in the firmware (by setting the value to true instead of false), and it did the same thing, but the other way around - it would only go down. To set the Z axis home offset on the 3d printer, you will use g-code commands including M206 for the home offset, M500 and M501 for the Marlin Firmware EEPROM feature, and G1 for controlled move to Z axis zero position. i just have trouble make the Z axis and/or the gcode with slic3r be the correct one, x, y, and e, seems to work fine, but Z keeps struck at the Z home position, on the gcode it only move .325 on the firs Z position, i dont get to Z One of two things will happen, the paper or feeler gauge will be tight or loose. As soon Check the fit of the paper - if it is good, and the nozzle seems to be at the correct height, then we are done with the calibration. x and y homing works awesome. nothing I do seems to change this. The machine will then move a further -0.7mm in Z to G1 Z2.0 F3000 ;Move Z Axis up G1 X232 Y20 Z0.28 F5000.0 ;Move to start position G1 X232 Y200.0 Z0.28 F1500.0 E15 ;Draw the first line G1 X232 Y200.0 Z0.28 F5000.0 ;Move to side a little G1 X232 Y20 Z0.28 F1500.0 E30 Navigate back to the z axis movement and increase the z axis by rotating the knob clockwise to about 2.0 representing 2mm. My machine has a zero point which is not over the build platform, so to get the nozzle over the platform I have to move the x and y axis. The Bed is a 200 by 200 job. I tried swapping the pins for the clip and the plate. In Marlin I had to set the #define DEFAULT_AXIS_STEPS_PER_UNIT for the z axis to 1600 to get the z axis to move 10 mm when commanded to move 10 mm.. What would be the pros and cons of going to half or full steps and Problem is, the Z axis does not move up while printing! I can move it up however far I want, to let's say x+15mm. When the z axis homes , it touches the endstop and moves up and homes again , but when moving down to home the second time , it moves extremely slowly , it takes 1 minute to hit the endstop again. When the Z axis is secured with smooth rods, along with threaded rods which have bearings on one end that move it up and down, you won’t have this problem. Once you have edited it, we are going to indicate to our dear Marlin that our 3D printer has a limit switch (sensor) on the Z axis. , and say the extruder head is at distance x from the bed was having the motors lock up moves...
